Mobile Audiometric Testing: On-Site Workplace Hearing Tests for Australian Employers

By Isaac Patturajan, MAIOH

Hearing damage from workplace noise exposure is one of the most common occupational health hazards in Australia. Yet many employers struggle to deliver audiometric testing to their workforce without disrupting operations, losing productivity, or requiring workers to take time away from site.

Mobile audiometric testing solves this problem. By bringing certified testing services directly to your workplace—whether that’s a mining site in Western Australia, a construction site in inner-city Melbourne, or an agricultural facility in regional Queensland—mobile testing removes the barriers to hearing health compliance and worker protection.

This comprehensive guide explains what mobile audiometric testing is, why it’s superior to clinic-based alternatives, how it works in practice, and how to book a service that meets Australian WHS regulations and industry standards.

What Is Mobile Audiometric Testing?

Mobile audiometric testing is a workplace hearing assessment service delivered on-site at your employer’s premises using a specially equipped mobile testing unit (typically a van or portable booth setup). A qualified audiometrist or occupational health professional conducts standardised hearing tests in a sound-attenuating booth that meets strict Australian and New Zealand standards.

Unlike clinic-based testing, mobile audiometric testing brings the equipment, expertise, and compliance framework to you. Workers don’t need to travel to an external clinic, take time away from work, or navigate unfamiliar healthcare settings. The testing happens on your site, during your scheduled working hours or at a time that suits your operations.

The result is a comprehensive hearing assessment that:

  • Measures hearing sensitivity across multiple frequencies (typically 500Hz to 8000Hz)
  • Compares results against Australian audiometric testing standards
  • Identifies workers at risk of noise-induced hearing loss (NIHL)
  • Creates a baseline for future monitoring and trend analysis
  • Generates compliant reports for your WHS records and regulatory obligations

Mobile audiometric testing is designed specifically for employers with 50+ workers (though services can be tailored for smaller teams). It’s the practical solution for industries where workers are geographically dispersed, based remotely, or unable to leave their worksite without significant operational disruption.

Why On-Site Testing Beats Clinic-Based Audiometric Assessment

Clinic-based audiometric testing has significant limitations for employers managing hearing health across dispersed or large workforces. Mobile audiometric testing directly addresses every one of these challenges.

1. Eliminates Worker Downtime and Lost Productivity

When workers travel to an external clinic for testing, you lose productivity time on two fronts: the travel itself plus the appointment duration. A worker might spend 1–2 hours away from site for a 20-minute test. Multiply this by 100 workers and you’ve lost 100–200 hours of operational capacity.

Mobile testing eliminates this friction. Workers complete their test on-site during scheduled breaks or allocated time blocks, then return immediately to their tasks. The testing happens around your operations, not the other way around.

2. Delivers Higher Attendance and Compliance Rates

External clinics create friction that suppresses participation. Workers forget appointments, struggle with logistics, or deprioritise the test because it requires extra effort. Typical clinic-based programs see 60–75% attendance rates.

On-site testing dramatically improves compliance because:

  • No travel barrier—workers can test during their normal shift
  • Peer participation—workers see colleagues getting tested, normalizing the process
  • Employer coordination—you can schedule testing directly into work plans
  • Familiar environment—workers feel more comfortable on their own site

Mobile testing programs consistently achieve 85–95% attendance rates, ensuring your hearing health program reaches the workers who need it most.

3. Provides More Accurate Baseline Results

The journey to a clinic exposes workers to ambient noise exposure before their test. A tradesperson traveling through city traffic, a mining worker who must commute across the site, or a construction worker on public transport—all arrive with elevated noise exposure that hasn’t had time to resolve.

AS/NZS 1269.4:2014 specifies a 14-hour noise-free period before testing to ensure accurate baseline results. When testing happens on-site, workers are already in a noise-controlled environment and can easily meet this quiet period requirement.

The result: more reliable audiometric data that accurately reflects each worker’s baseline hearing threshold, enabling better trend monitoring and earlier identification of hearing loss.

4. Removes Transport and Logistics Barriers

For regional, remote, and rural employers—mines, farms, agricultural facilities, isolated manufacturing plants—sending workers to a city clinic is operationally impractical. Travel time might be 3–4 hours each way. Coordinating transport for large groups becomes logistically nightmarish.

Mobile testing services specifically address this gap. We travel to your location, meaning regional and remote employers finally have practical access to compliant hearing health programs.

5. Enables Faster Turnaround from Test to Report

Mobile testing typically delivers employer reports within 24–48 hours of testing, compared to 5–10 days for clinic-based programs. This faster turnaround means you can identify workers requiring referral or follow-up faster, and action any hearing health interventions more quickly.

How Mobile Audiometric Testing Works: Step-by-Step Process

Understanding the mobile testing process helps you prepare your workplace and set realistic expectations for your workers. Here’s what happens from booking through to results delivery.

Step 1: Booking and Scheduling

The process begins with a conversation about your requirements. You’ll typically provide:

  • Number of workers requiring testing
  • Workplace location(s)
  • Preferred testing dates and times
  • Any workers with known hearing issues or language barriers requiring additional support
  • Site accessibility and parking information for the mobile unit

Most providers require 2–4 weeks’ notice to schedule a mobile testing session, though some can accommodate urgent requests. Lead time depends on your location (metro areas have faster turnaround than remote sites) and the provider’s schedule.

Step 2: Pre-Test Communication to Workers

Your employer prepares workers with clear information about:

  • What the test involves and why it matters for their health
  • Test duration (typically 15–20 minutes per worker)
  • When and where they’ll be tested
  • The 14-hour quiet period requirement—critical for accuracy (explained in detail below)
  • Any items to bring or information to provide

This communication is essential. Workers who understand the test purpose and requirements engage better and maintain the noise-quiet period, resulting in higher-quality data.

Step 3: Mobile Testing Unit Arrives On-Site

The mobile testing van or portable booth unit arrives at your workplace at the scheduled time. The testing provider sets up the soundproof booth, calibrates equipment, and confirms safe and accessible testing procedures with your site safety team.

Setup typically takes 30–60 minutes depending on the complexity of your site and the number of booths being deployed (large testing days might use 2–3 booths running in parallel to maximise throughput).

Step 4: Worker Registration and Pre-Test Questionnaire

As each worker arrives for their test, they complete a brief pre-test questionnaire covering:

  • Demographic information (age, years in role, tenure at workplace)
  • Noise exposure history (previous roles, recreational noise exposure)
  • Hearing health history (previous tests, hearing loss, tinnitus, ear infections)
  • Current symptoms (any discomfort, recent loud noise exposure)
  • Medications affecting hearing

This context helps the audiometrist interpret test results correctly and identify workers at particular risk.

Step 5: The 14-Hour Quiet Period Requirement (AS/NZS 1269.4)

Before entering the sound-attenuating booth, the audiometrist confirms that each worker has maintained a 14-hour noise-free period since their last significant noise exposure.

This requirement exists because continuous noise exposure temporarily shifts your hearing threshold (a condition called temporary threshold shift, or TTS). Testing immediately after noise exposure would create a false baseline that doesn’t represent your true hearing sensitivity.

Practically, this means:

  • If your workplace operates during the day, workers ideally complete their 14-hour quiet period overnight (leaving site at 5 PM, testing the next morning)
  • If testing happens after a night shift, the 14-hour period runs through the following day
  • For optimal results, testing typically occurs at the start of the working week or after a rest day

If a worker cannot meet the 14-hour quiet period (for example, they’ve just come from a noisy task), the audiometrist documents this and flags the result for interpretation with caution or requests re-testing once the quiet period is observed.

Step 6: Pure Tone Audiometry in the Sound-Attenuating Booth

The actual hearing test takes 15–20 minutes per worker. The process:

Booth Entry: The worker enters the sound-insulated booth wearing calibrated headphones. The booth is designed to meet AS/NZS 1269.4 ambient noise limits, meaning external noise doesn’t interfere with the test signal.

Test Signal Presentation: The audiometrist presents pure tone signals at different frequencies (typically 500Hz, 1000Hz, 2000Hz, 3000Hz, 4000Hz, 6000Hz, and 8000Hz) and varying sound levels. Testing usually covers both ears.

Worker Response: The worker raises their hand or presses a button whenever they hear a tone, indicating the quietest sound they can detect at each frequency (their threshold).

Data Recording: Results are recorded on an audiogram—a graph showing hearing sensitivity across frequencies. Normal hearing is typically between -10 and 20 dB HL (hearing level). Values above 20 dB HL indicate hearing loss at that frequency.

Test Duration and Throughput: A single test takes 15–20 minutes. With one sound-attenuating booth, a mobile testing day can typically accommodate 20–30 workers. With two booths running simultaneously, capacity increases to 40–60+ workers depending on break schedules and changeover time.

Step 7: Immediate Result Review with the Tester

Upon completing the test, the qualified audiometrist reviews the results with the worker privately, explaining:

  • Their hearing threshold at each frequency tested
  • Whether results are normal or indicate hearing loss
  • How their results compare to their age and occupational context
  • Any recommendations for hearing protection or follow-up

This discussion is reassuring for workers and ensures they understand their baseline before leaving the booth.

Step 8: Same-Day or 48-Hour Report Delivery

The testing provider compiles comprehensive employer reports within 24–48 hours, containing:

  • Summary statistics for your entire cohort tested
  • Breakdown of normal vs. abnormal results
  • Trend analysis if comparing against previous testing
  • Individual worker results (typically confidential to the employer, with individual workers receiving their own results privately)
  • Recommendations for workers requiring follow-up or referral to an audiologist
  • Compliance documentation confirming AS/NZS 1269.4 adherence

Equipment Used in Mobile Audiometric Testing

The quality of mobile audiometric testing depends critically on the equipment used. Here’s what professional mobile testing services deploy.

Calibrated Audiometers

The core piece of equipment is a clinical-grade audiometer—a device that generates pure tone signals at precise frequencies and sound levels. Professional mobile services use audiometers that are:

  • Calibrated to ISO 8253-1 standards—ensuring test signals are accurate and traceable to international standards
  • Recalibrated every 12 months (at minimum) by accredited calibration laboratories
  • Equipped with data logging software that automatically records test parameters, worker responses, and environmental conditions
  • Digital and cloud-enabled, allowing real-time data transfer to secure servers and faster report generation

The audiometer’s accuracy is critical. A miscalibrated device could either miss genuine hearing loss or incorrectly flag workers with normal hearing.

Sound-Attenuating Booths

Testing must occur in an environment where the ambient noise level doesn’t interfere with the test signals. AS/NZS 1269.4:2014 specifies exact ambient noise limits for audiometric testing:

Frequency (Hz) Maximum Ambient Noise Level (dB)
125 45
250 40
500 35
1000 30
2000 30
4000 30
8000 35

Professional mobile testing booths achieve these limits through:

  • Multi-layer acoustic insulation in walls and ceiling
  • Vibration-damping floors that isolate the booth from external vibration (important on construction sites or near heavy machinery)
  • Acoustic sealing around doors and cable penetrations
  • Internal acoustic foam treatment that reduces internal reverberation

Portable booths typically achieve 30–40 dB attenuation (meaning noise is reduced by 30–40 dB compared to outside). Mobile vans, by virtue of their larger mass and professional construction, often achieve 40–50 dB attenuation.

Before testing begins, the testing provider uses a sound level meter (calibrated to IEC 61672 standards) to verify that the booth meets ambient noise limits at all frequencies.

Calibrated Headphones (Audiometric Earphones)

The headphones delivering the test signal must also be calibrated to ISO standards. Professional audiometric earphones are:

  • Frequency-response-certified across the testing range (typically 125Hz–8000Hz)
  • Calibrated for SPL (sound pressure level) accuracy within ±3 dB across the range
  • Individual pair-calibrated (not generic across all headphone pairs)
  • Regularly checked for physical damage, frequency response drift, or pad degradation

Professional services maintain backup headphone pairs to ensure testing can continue if a pair needs replacement or recalibration.

Testing Software and Data Management

Modern mobile testing services use cloud-based or networked software systems that:

  • Record test parameters automatically—frequency, level, response time, number of presentations
  • Generate audiograms in real-time
  • Flag abnormal results for audiometrist review
  • Manage worker data securely with encryption and access controls
  • Enable trend analysis comparing results year-over-year
  • Generate compliance reports automatically formatted for WHS documentation

Who Conducts Mobile Audiometric Testing—Qualification Requirements

The qualifications of the person conducting your test directly affect the validity and reliability of your hearing health program. Australian regulations and professional standards specify who can legally conduct workplace audiometric testing.

Audiometrists

Accredited Audiometrists are the gold standard for mobile audiometric testing. They must hold:

  • A degree in audiology (bachelor’s level minimum)
  • AHPRA (Australian Health Practitioner Regulation Agency) registration as an audiologist or hearing aid dispenser
  • Specific training in occupational audiometry and workplace hearing assessment
  • BOHC (Board of Hearing Care Australia) accreditation for occupational audiometric testing (an additional certification beyond basic audiologist training)
  • Continuing professional development (CPD) hours to maintain their accreditation

Audiometrists understand normal and abnormal hearing patterns, can identify conditions like conductive hearing loss or sudden sensorineural loss, and can recognise test results that may be artefactual or require follow-up investigation.

Occupational Health Nurses

Registered Occupational Health Nurses (with specific audiometric training) can also conduct mobile audiometric testing in Australia. They must hold:

  • Registration as a Registered Nurse (RN) with AHPRA
  • Post-graduate or specialist training in occupational health nursing
  • Specific training and competency assessment in audiometric testing procedures
  • Ongoing training in hearing health and noise-induced hearing loss

Many occupational health nurses are embedded in large employers’ health teams and conduct baseline testing, then refer abnormal results to audiologists for more detailed assessment.

Audiometric Technicians (Limited Scope)

Some testing services employ audiometric technicians under the supervision of an audiometrist or occupational health nurse. Technicians conduct the actual test administration but must have training in:

  • Proper headphone placement and worker positioning
  • Test signal presentation
  • Quality assurance procedures
  • Data recording and safety protocols

However, result interpretation, identification of abnormal results, and clinical decision-making must remain with a qualified audiometrist or occupational health nurse.

What to Verify When Booking

When you book a mobile testing service, always confirm:

  • The qualifications of the person who will conduct testing at your site
  • Their professional registration with AHPRA or relevant regulatory body
  • BOHC accreditation (if they’re an audiometrist)
  • Current CPD/continuing education status
  • Experience in workplace or occupational audiometric testing
  • Backup arrangements if your assigned tester becomes unavailable

Typical Throughput: How Many Workers Per Day?

The number of workers you can test in a single mobile testing day depends on several factors:

Single-Booth Setup: 20–30 Workers Per Day

With one sound-attenuating booth:

  • Test duration per worker: 15–20 minutes
  • Turnaround/changeover time: 3–5 minutes
  • Total per-worker cycle: 18–25 minutes
  • Testing hours available: typically 6–7 hours (accounting for setup, lunch, and teardown)
  • Realistic daily capacity: 20–30 workers

Dual-Booth Setup: 40–60+ Workers Per Day

With two simultaneous booths:

  • Each booth operates independently with staggered worker flow
  • Combined capacity approximately doubles to 40–60 workers
  • Optimal for larger employers or multi-site testing days
  • Requires adequate space on your site for two booths

Factors Affecting Daily Throughput

Site Layout and Access: If workers are spread across a large site (e.g., a mining operation or agricultural facility), time spent commuting workers to/from the testing area reduces effective testing time.

Worker Availability: If testing must work around production schedules, shift patterns, or maintenance windows, this constrains testing hours.

Pre-Test Communication Effectiveness: If workers don’t know their testing time or are unprepared, no-shows and delays reduce throughput.

Noise-Exposure Patterns: If workers are regularly exposed to high noise levels, scheduling testing when the 14-hour quiet period is feasible constrains options.

Most providers will discuss your site’s specific constraints during booking and adjust scheduling to maximise throughput while maintaining test quality.

What Happens With Testing Results

Understanding how results are used and distributed is critical for worker confidence and legal compliance.

Individual Worker Results

Each worker receives their own audiometric results, typically within 24–48 hours of testing. These results include:

  • Their personal audiogram (graph of hearing thresholds)
  • Comparison to normal hearing ranges for their age
  • Explanation of what the results mean in plain language
  • Any recommendations for follow-up (e.g., “hearing protection strategies” or “consider follow-up with an audiologist”)

Results are typically confidential to the individual worker and your employer—not shared with colleagues.

Employer Summary Report

Your employer receives a comprehensive report summarising:

  • Cohort statistics: Total workers tested, percentage with normal hearing, percentage with hearing loss
  • Hearing loss breakdown: Number of workers showing mild, moderate, or significant hearing loss
  • Frequency-specific data: Which frequencies are most affected (important for understanding whether loss is noise-induced or age-related)
  • Trend analysis: If comparing to previous year’s testing, showing which workers’ hearing has declined and at what rate
  • Referral recommendations: Specific workers who should be referred to an audiologist for diagnostic assessment
  • Compliance documentation: Confirmation that testing was conducted to AS/NZS 1269.4 standards

Referral Pathways for Abnormal Results

Workers with abnormal audiometric results should be managed through a clear pathway:

  • Notification: The worker is informed of their result and the need for follow-up
  • Audiologist referral: The worker is referred to an audiologist for diagnostic assessment (audiometry in a clinic setting is more detailed than occupational screening)
  • Hearing aid assessment: If hearing loss is confirmed, the worker may be assessed for hearing aid fitting
  • Workplace accommodation: Depending on the degree and type of hearing loss, workplace modifications may be needed (e.g., visual alarms, better communication systems)
  • Compensation eligibility: In some cases, workers with occupational hearing loss may be eligible for workers’ compensation claims

Your mobile testing provider should have referral pathways established to local audiologists and occupational health specialists, making this follow-up process seamless.

Mobile Audiometric Testing for Remote and Regional Sites

One of mobile testing’s greatest advantages is its accessibility to regional, remote, and rural employers who previously had no practical way to deliver hearing health screening.

How We Service Remote Sites

Mining Operations: Whether your mine is in the Pilbara, the Darling Downs, or Tasmania, mobile testing providers can schedule multi-day testing events at your site. Large mining employers often arrange annual testing for hundreds of workers across multiple days.

Agricultural and Farming Operations: Family farms and large agricultural enterprises can now conduct hearing health screening on-site without workers traveling to regional towns or cities.

Construction Sites: Large construction projects can bring testing directly to the site, testing workers in real-time as they rotate through roles and exposure levels.

Regional Manufacturing and Processing Plants: Food processing facilities, textiles, engineering shops, and other regional manufacturers benefit from on-site testing that minimises disruption to production schedules.

Multi-Site Scheduling

For employers with multiple sites across a region or state, mobile testing providers can arrange sequential site visits, testing 20–30 workers per day across multiple locations. This is far more efficient than asking workers to travel to a central location.

Travel Allowances and Lead Times

For truly remote sites (>3 hours’ drive from major centres), you can expect:

  • Extended lead times (4–8 weeks) to schedule testing during provider routes
  • Travel surcharges to cover provider travel costs
  • Flexibility in scheduling (testing may be grouped with other regional clients to minimise travel)

Despite these factors, remote site testing remains far more practical than requiring workers to travel to distant clinics.

Industries We Serve

Mobile audiometric testing is particularly valuable across these high-noise industries:

Mining and Quarrying

Mining operations expose workers to sustained high noise from heavy machinery, blasting, and drilling. AS/NZS 1269.4 requires baseline audiometric testing for all workers exposed to noise above 80 dB(A) and regular monitoring throughout employment. Mobile testing directly addresses this requirement.

Construction

Construction sites involve multiple noise sources (power tools, machinery, demolition). Large construction contractors use mobile testing to conduct baseline testing for new workers and annual monitoring to track hearing health trends.

Manufacturing

Industrial manufacturing, metalworking, automotive production, and textile mills all expose workers to sustained noise. Mobile testing brings compliance testing to factory floors without disrupting production.

Agriculture and Horticulture

Farm machinery, grain handling equipment, and irrigation systems generate high noise levels. Mobile testing makes hearing health monitoring practical for dispersed agricultural workforces.

Transport and Logistics

Truck drivers, train operators, bus drivers, and warehouse workers experience prolonged noise exposure. Mobile testing can visit depots and logistics hubs to screen large numbers of transport workers efficiently.

Food Processing and Beverage Production

Food processing plants, bottling facilities, and beverage production lines involve continuous noise from machinery and equipment. Mobile testing delivers rapid compliance screening for large processing workforces.

Defence and Military

Defence facilities, naval bases, and military training grounds involve extremely high noise exposure (weapons firing, machinery, aircraft). Mobile testing provides rapid screening for military and defence personnel.

Entertainment and Events

While less common, entertainment venues, concert halls, event management companies, and sound engineering firms may benefit from occupational hearing monitoring for staff regularly exposed to high sound levels.

Compliance Outcomes: Meeting Australian Standards and Regulations

Mobile audiometric testing is designed specifically to help employers meet their legal obligations under Australian workplace health and safety law.

AS/NZS 1269.4:2014 Compliance

Australian/New Zealand Standard 1269.4:2014 is the primary standard governing occupational audiometric testing. Compliance means:

  • Qualified personnel: Testing conducted by BOHC-accredited audiometrists or equivalent occupational health professionals
  • Calibrated equipment: Audiometers calibrated to ISO 8253-1, with annual recalibration
  • Sound-attenuating booths: Meeting ambient noise limits specified in the standard
  • 14-hour quiet period: Workers maintain noise-free period before testing
  • Documentation: Records of testing methodology, worker details, test parameters, and results
  • Confidentiality: Secure storage of sensitive health information

Professional mobile testing services design their entire operation to meet these requirements, so you can be confident your testing program is compliant.

WHS Regulation 58 Compliance

Model Work Health and Safety Regulations, Part 6 (Section 58) requires employers to ensure the health and safety of workers exposed to noise, including:

  • Identifying and assessing noise exposure levels
  • Implementing hearing protection strategies when exposure exceeds safe limits
  • Providing medical surveillance (which includes audiometric testing) for workers exposed to noise
  • Maintaining records of exposure and health outcomes

Mobile audiometric testing provides the medical surveillance component of this obligation. When combined with noise exposure monitoring and hearing protection programs, it demonstrates comprehensive compliance with Regulation 58.

State-Specific Compliance

Australia’s states and territories have their own specific WHS legislation (though all are based on the Model WHS Regulations). Mobile testing providers should be familiar with state-specific requirements:

  • New South Wales: WHS Act 2011 and Work Health and Safety Regulation 2011
  • Victoria: Occupational Health and Safety Act 2004 and OHS Regulations 2017
  • Queensland: Work Health and Safety Act 2011 and WHS Regulation 2011
  • South Australia: Return to Work Act 2014 and Occupational Health, Safety and Welfare Regulations 1995
  • Western Australia: Work Health and Safety Act 2020 and WHS Regulations 2022
  • Tasmania: Work Health and Safety Act 2012 and Work Health and Safety Regulations 2012
  • Australian Capital Territory: Work Health and Safety Act 2011 and WHS Regulation 2011

A professional mobile testing provider will confirm compliance with your state’s specific requirements when you book.

Audiometric Data Retention and Privacy

Audiometric results are sensitive health information and must be handled securely. Compliance requires:

  • Secure storage: Encrypted digital storage or secure physical files
  • Access controls: Only authorised personnel (typically occupational health staff, WHS managers) can access worker results
  • Privacy compliance: Adherence to Privacy Act 1988 (Cth) and state-specific privacy legislation
  • Retention periods: Generally retained for the duration of employment plus a minimum period (often 5–7 years) to allow trend analysis and historical comparison
  • Destruction protocols: Secure deletion or destruction when retention period expires

When you book a mobile testing service, ask about their data security and privacy practices to ensure your workers’ health information is protected.

Pricing Overview

Mobile audiometric testing costs vary based on several factors:

Per-Person Pricing

Most providers charge per worker tested, typically in the range of:

  • Metro/urban areas: $65–$90 per worker (larger groups may qualify for discounts)
  • Regional areas: $80–$110 per worker (reflecting additional travel time)
  • Remote/isolated sites: $100–$150+ per worker (for sites requiring extended travel)

Factors Affecting Price

Group Size: Larger testing cohorts (100+ workers) usually qualify for per-person discounts due to improved efficiency.

Location: Sites within major metropolitan areas typically cost less than regional or remote locations due to reduced travel time.

Site Accessibility: Difficult-to-access locations (tight parking, restricted hours, unusual site layout) may incur surcharges.

Special Requirements: Language support, additional reporting, trend analysis, or follow-up audiologist referrals may attract additional costs.

Timing: Urgent scheduling (less than 2 weeks notice) may incur rush fees.

Frequently Asked Questions About Mobile Audiometric Testing

1. Do you come to regional and remote areas?

Yes. Mobile testing services specifically exist to serve regional, remote, and rural employers. We provide services across NSW, VIC, QLD, SA, WA, TAS, and ACT. For truly remote sites, you can expect longer lead times (4–8 weeks) to coordinate travel, and may qualify for travel cost allowances. However, on-site testing remains far more practical than asking workers to travel to distant clinics.

2. How long does each test take?

Each worker’s audiometric test takes approximately 15–20 minutes in the sound-attenuating booth. This includes the pure tone test itself plus time for the worker to settle and accustom to the booth environment. Pre-test questionnaires add another 5–10 minutes, so total time per worker is typically 20–30 minutes from arrival to departure.

3. What equipment do you use?

Professional mobile services use calibrated clinical-grade audiometers (calibrated to ISO 8253-1 and recalibrated annually), sound-attenuating booths meeting AS/NZS 1269.4 ambient noise limits, calibrated audiometric headphones, and digital data management software. All equipment is regularly tested and verified to ensure accuracy and compliance.

4. Do I need to prepare workers before testing?

Yes. Workers should be informed about the testing date, time, and location. Most importantly, they should understand the 14-hour quiet period requirement—they should avoid high noise exposure for 14 hours before their test to ensure accurate baseline results. This typically means testing workers at the start of the working week or after a rest day, after they’ve spent the previous 14 hours in a relatively quiet environment.

5. What if a worker can’t meet the 14-hour quiet period?

If a worker cannot maintain the 14-hour quiet period (for example, they’ve just come from a noisy task), the audiometrist will document this on their test record. Results are still valid but are interpreted with awareness that temporary threshold shift may be present. Where possible, testing can be rescheduled for a time when the quiet period is feasible, or the result can be noted as a baseline with re-testing recommended once the quiet period is observed.

6. Are the tests uncomfortable or painful?

No. Audiometric testing is completely non-invasive and painless. Workers sit in a quiet booth wearing headphones and press a button or raise their hand when they hear a sound. The loudest sounds presented are no louder than normal conversation and are significantly quieter than workplace noise exposure. Many workers find the test relaxing.

7. How quickly do we get results?

Individual workers typically receive their personal results within 24 hours of testing. Your employer summary report is usually provided within 24–48 hours, allowing you to identify workers requiring follow-up and action any necessary hearing health interventions quickly.

8. Are results confidential?

Yes. Individual worker test results are confidential health information. Workers receive their own results privately. Your employer receives a summary report showing group statistics and identifying specific workers who need follow-up, but not sharing individual results with other workers. All data is stored securely in compliance with Privacy Act 1988 (Cth) and state privacy legislation.

9. What if a worker’s test shows hearing loss?

If a worker’s test shows hearing loss compared to normal thresholds for their age, they’ll be informed and provided information about what this means. The provider will typically recommend follow-up with an audiologist for more detailed assessment. If the hearing loss appears to be occupational (noise-induced), the worker should be counselled on hearing protection strategies and may be eligible for occupational health follow-up or, in some cases, workers’ compensation assessment.

10. How is mobile testing different from testing at a clinic?

Mobile testing eliminates worker travel time and productivity loss, dramatically improves attendance rates (85–95% vs. 60–75% for clinic-based programs), ensures workers maintain the 14-hour quiet period more easily, and provides faster turnaround from testing to results. It’s specifically designed for employers with dispersed or large workforces and geographically remote operations.

11. Is mobile testing compliant with Australian standards?

Yes, when conducted by qualified providers, mobile testing is fully compliant with AS/NZS 1269.4:2014 and meets WHS Regulation 58 medical surveillance obligations. Professional providers design their equipment, procedures, and personnel to meet all applicable standards and regulations.

12. How often should we conduct audiometric testing?

This depends on your workers’ noise exposure levels and the regulatory requirements for your industry. AS/NZS 1269.4 recommends initial baseline testing for all workers exposed to noise above 80 dB(A), then regular monitoring (often annual) to track hearing health trends. Your mobile testing provider can advise on the appropriate frequency for your workplace and industry.
