Introduction: Taking Control of Your Testing Schedule

Organising audiometric testing can feel overwhelming if you’ve never coordinated it before. You’re juggling worker availability, operational continuity, provider scheduling, and compliance requirements. This guide walks WHS managers through each step of the process, from initial planning to post-testing follow-up.

By following this structured approach, you’ll eliminate guesswork and ensure a smooth testing day that maximises worker participation and produces valid, compliant results.

Step 1: Planning Timeline – When to Book

Small Groups (Under 50 Workers): 2-4 Weeks Lead Time

If your testing cohort is small, book your provider 2-4 weeks in advance. This allows time for provider confirmation, worker notification, and basic scheduling coordination without overwhelming your planning timeline.

Medium Groups (50-150 Workers): 4-6 Weeks Lead Time

Medium-sized programs benefit from 4-6 weeks of advance planning. This window allows for multi-day scheduling coordination, alternative arrangements for absent workers, and ensures worker notification reaches all staff with adequate planning time.

Large Groups (150+ Workers): 8-12 Weeks Lead Time

Major programs involving hundreds of workers require 8-12 weeks. This extended timeline allows for multi-site coordination, shift scheduling across extended periods, FIFO workforce rotation accommodation, and contingency planning.

Seasonal or Rotating Workforces: Staggered Annual Schedule

For agriculture, construction, or other seasonal sectors, plan your annual testing schedule 12 weeks in advance, mapping testing windows to workforce availability across the year. This prevents last-minute scrambles and ensures testing occurs when workers are available.

Step 2: Identify Noise-Exposed Workers

Before booking, determine which workers require audiometric testing. Under AS/NZS 1269, testing is required for workers exposed to noise at or above 85 dB(A) LEQ for an 8-hour period (or equivalent daily noise exposure).

Who Typically Requires Testing?

• Manufacturing line operators, machinists
• Construction site workers (operators, riggers, labourers)
• Mining personnel (underground and surface)
• Warehouse and logistics personnel (loading/unloading, machinery operation)
• Hospitality and entertainment venue staff (exposed to sustained music noise)
• Agricultural workers (tractor operators, chainsaws, grain handling)
• Utilities and infrastructure workers (power stations, water treatment, telecommunications)

How to Compile Your List

1. Review your noise risk assessment (required under WHS legislation)
2. Identify job roles classified as 85 dB(A)+ exposure
3. Count current workers in those roles
4. Add workers who were in those roles in the past year (they may require 2-year follow-up testing)
5. Record names, employee IDs, current roles, and testing history
6. Flag any workers with existing hearing loss or previous significant threshold shift

Provide this list to your testing provider to confirm the testing scope and help them prepare appropriately.

Step 3: Worker Notification and Communication

First Communication: Announcement (4-6 Weeks Before Testing)

Send an initial message to all noise-exposed workers explaining that audiometric testing is scheduled. Include:

• Purpose: “This hearing test is part of our commitment to protecting your health and complying with workplace safety law.”
• Scope: “All workers in noise-exposed roles are required to participate.”
• Timing: “Testing is scheduled for [dates]. Your specific testing time will be confirmed closer to the date.”
• Duration: “Your test takes approximately 15 minutes.”
• Confidentiality: “Your results are private and protected by health privacy law.”

Second Communication: Specific Appointment Details (2 Weeks Before)

Issue individual appointment notifications or shift-based testing schedules. Include:

• Worker’s name and employee ID
• Date and time of their test
• Location (quiet room or mobile van location)
• Pre-test instructions (see section below)
• Contact person if they need to reschedule
• What to bring (minimal — usually just ID, but clarify for your site)

Communication Template

Subject: Your Audiometric Testing Appointment – [Date]

Dear [Worker Name],
Your hearing test is scheduled for [Date] at [Time] at [Location].
This test takes about 15 minutes. Please avoid loud noise (including music, power tools, or machinery) for 14 hours before your test. Your results will be confidential and used only to protect your hearing health at work.
If you can’t make this appointment, contact [Name] immediately on [Phone] to reschedule.
Questions? Ask [Contact] on the day.
Thank you for your participation in our hearing safety program.

Step 4: Scheduling and Logistics

Shift-Based Scheduling

Coordinate testing times around your shift patterns:

• Day shift: Test after shift completion (late afternoon) or during a designated break period
• Afternoon shift: Test before shift start or during handover time
• Night shift: Test after shift end (early morning) or on their next rostered day off
• Mixed shifts: Offer testing at the end of each shift to accommodate all workers without disrupting production

Production Considerations

Consult with operational managers about the least disruptive testing windows:

• Avoid high-demand production periods
• Test during planned maintenance shutdowns if available
• Stagger testing across multiple days rather than testing all workers on a single day if operations can’t sustain the loss of 5-10 workers for 2-3 hours
• For FIFO or remote rotations, test during rotation changeover when workers are already on-site or between shifts

Quiet Room or Testing Van Preparation

If using an on-site quiet room: Ensure the room meets AS/NZS 1269.4 acoustic standards, with ambient noise limits of no more than: 39.5 dB at 250 Hz, 39.5 dB at 500 Hz, 39.5 dB at 1000 Hz, 43 dB at 2000 Hz, 47 dB at 3000 Hz, 47 dB at 4000 Hz, 51 dB at 6000 Hz, and 51.5 dB at 8000 Hz. Clear the room of unnecessary equipment and ensure comfortable seating outside.

If using a mobile testing van: Confirm parking location with clear access, adequate space around the van, power supply access if required, and weather protection for workers waiting to be tested.

Step 5: Pre-Test Instructions for Workers

The 14-Hour Quiet Period

The most critical pre-test requirement is avoiding loud noise for 14 hours before testing. Explain to workers that this prevents temporary threshold shift (TTS) — a temporary elevation in hearing thresholds caused by recent noise exposure — from masking their true baseline hearing status.

What “No Loud Noise” Means

• Avoid: Personal audio devices at high volume, concerts or live music venues, power tools, machinery, high-speed vehicles
• Minimise: Vehicle noise during commute (don’t blast the radio), ambient workplace noise if testing is after a shift
• Use protection: If loud noise is unavoidable, use appropriate hearing protection and minimise exposure duration
• Ideal scenario: Test during a quiet period (e.g., morning before shift start, or morning after a night shift)

Other Pre-Test Considerations

• Workers should be well-rested (avoid testing immediately after exhausting 12-hour shifts)
• Avoid excessive caffeine immediately before testing (can cause temporary hearing threshold elevation)
• Ensure earwax isn’t blocking the ear canal (impacted earwax can affect results; workers can clean ears beforehand but shouldn’t use cotton buds or probes)
• Allow workers to use the bathroom before testing (a full bladder can cause subtle hearing threshold elevation)

Communication of Pre-Test Instructions

Include pre-test instructions in appointment notifications and reinforce them verbally or in written briefings. Consider creating a simple one-page handout: “5 Ways to Prepare for Your Hearing Test.”

Step 6: Day-of Coordination Checklist

48 Hours Before Testing

• Confirm provider arrival time, parking location, and contact person
• Verify quiet room is clean, clear, and meets acoustic requirements (if applicable)
• Test any on-site audio equipment or mobile van parking access
• Prepare worker list in agreed format for the audiometrist
• Arrange signage directing workers to testing location
• Notify site management that testing is commencing

Morning of Testing

• Arrive early to greet provider and confirm setup logistics
• Ensure quiet room/van area is kept quiet (no loud conversations, announcements, or machinery noise nearby)
• Prepare seating for workers awaiting testing
• Brief workers on arrival order and location
• Confirm at least one WHS representative will be on-site for the full testing duration

During Testing

• Manage worker flow — direct workers to the testing area on schedule
• Keep the area quiet and calm
• Respond to worker questions (direct technical questions to the audiometrist)
• Maintain a sign-in sheet to track who has been tested
• Note any workers who didn’t arrive or failed to complete the test

Step 7: Managing Incomplete Results

Workers Who Don’t Attend

Track absences and contact workers within 48 hours to reschedule. Provide 2-3 alternative appointment times within the next 2-4 weeks. For workers who repeatedly miss appointments, investigate barriers (shift changes, communication issues, anxiety) and work with them to find a solution.

Failed Tests

A small percentage of tests may be “failed” if the worker cannot comply with testing instructions (excessive background noise, difficulty understanding instructions, or medical conditions affecting hearing temporarily). The audiometrist will advise. Reschedule failed tests for another day with fresh conditions.

Referrals for Audiological Follow-Up

If testing reveals significant hearing loss or a significant threshold shift (10+ dB change at 2, 3, or 4 kHz compared to baseline), the worker will be referred for follow-up assessment by an audiologist. Communicate referral recommendations to the worker and provide details of recommended audiologists or clinic services.

Tracking Incomplete Testing

Maintain a spreadsheet with: worker name, testing date assigned, attended (yes/no), result (pass/refer/failed), and rescheduled date if applicable. Complete all testing within 8 weeks of the initial testing window to maintain data currency.

Step 8: Post-Testing Steps

Receiving and Reviewing the Testing Report

Within 48 hours of the testing session, your testing provider will issue a summary report including:

• List of all workers tested, with pass/refer categorisation
• Identification of workers with threshold shifts or significant hearing loss
• Recommended follow-up actions
• Individual audiogram reports for each worker (either printed or digital)

Review the summary report with your health and safety representative and occupational health advisor to understand the implications for your workforce.

Distributing Individual Worker Results

Provide each worker with their individual audiogram report in a confidential setting. Offer to explain their result using plain language: What the test measures, how their current result compares to their baseline, what the categories mean (normal hearing, refer for audiological assessment, etc.), and any recommended actions (e.g., improved hearing protection, audiological assessment).

Filing Records

Establish a secure filing system for audiometric records:

• Confidentiality: Records contain health information and must be kept confidential. Store in a locked cabinet or secure digital system with access restricted to WHS and HR staff.
• Retention: Keep records for at least 5 years per AS/NZS 1269.4. Consider longer retention for liability protection.
• Digital vs paper: Increasingly, providers issue digital reports. Ensure secure backup and don’t store on shared drives without appropriate access controls.
• Worker access: Workers should have access to their own results upon request.

Reviewing Control Measures

Use testing results to inform your review of hearing loss prevention controls. If testing reveals:

• High baseline hearing loss prevalence: Review engineering controls (noise reduction, isolation, enclosure) and ensure hearing protection is being used correctly
• Significant threshold shifts: Investigate the cause, review work practices, and consider whether controls are being followed
• Referrals for audiological assessment: Ensure workers access follow-up care and consider whether additional control measures are needed for the affected worker

Communicating Results to Workers

WHS legislation requires that workers are informed of testing results that indicate hearing loss or a significant threshold shift. Ensure this communication is timely (within 2-4 weeks of testing) and clear. Offer opportunity for questions and discussion. Provide referral information if audiological follow-up is recommended.

Annual Review and Trend Monitoring

If workers required 2-year follow-up testing (i.e., they had a significant threshold shift), schedule that testing within the 2-year window. Use sequential test results to identify trends in individual hearing loss and adjust control measures accordingly.

Frequently Asked Questions

How far in advance should I book audiometric testing?

For small groups (under 50 workers), book 2-4 weeks in advance. For medium groups (50-150 workers), book 4-6 weeks in advance. For large programs (150+ workers), book 8-12 weeks in advance to secure provider availability and coordinate multi-site logistics.

What information do I need to provide to the audiometric testing provider?

You’ll need to provide: a list of workers requiring testing (name, employee ID, role, noise exposure classification), site location and access details, preferred testing dates and shift times, existing baseline audiogram dates (if applicable), and confirmation of your quiet room specifications or mobile van access.

How long does each worker’s testing take?

Each worker typically requires 12-15 minutes total: 2 minutes for registration, 5 minutes for the mandatory quiet period, 5-8 minutes for pure-tone testing, and 2-3 minutes for result discussion. Plan for 15-20 minutes per worker accounting for transitions.

What pre-test instructions should workers receive?

Workers should be instructed to avoid loud noise for 14 hours before testing. This includes not wearing personal audio devices, avoiding concerts or loud entertainment, minimising vehicle noise exposure during commute, and using appropriate hearing protection if unavoidable noise occurs.

What should I do if a worker doesn’t show up for their test?

Reschedule absent workers as soon as possible, ideally within 2-4 weeks. Maintain a tracking log to ensure no worker is missed. Workers have a WHS obligation to participate, but coordination is essential. For chronic non-compliance, consult your occupational health provider about alternative testing arrangements.

Can I test workers across multiple days or shifts?

Yes, multi-day testing programs are common. You can schedule testing across consecutive days, different shifts (morning, afternoon, night), or separate sessions for different work areas or teams. This approach reduces disruption to operations while ensuring complete testing coverage.

How should I communicate test results to workers?

Provide individual audiogram reports to each worker, ideally in a private setting. Explain their results in plain language, what the test measures, how their current result compares to their baseline, and what any recommendations mean. Offer opportunity for workers to ask questions about their hearing health.

How long should I keep audiometric testing records?

Maintain audiometric testing records for at least 5 years as required by AS/NZS 1269.4 and WHS legislation. Consider keeping records for the full duration of employment plus 5 years for liability protection, particularly for workers with significant hearing loss.

Conclusion: From Planning to Compliance

Organising a successful audiometric testing program requires attention to detail at each stage — from initial planning through to post-testing record management. By following this step-by-step approach, you’ll ensure high worker participation, valid testing data, and clear documentation of your compliance efforts.

The key to success is early planning, clear communication with workers, operational coordination with your management team, and systematic follow-up of results. When you make testing convenient and well-organized, worker attendance improves dramatically, and your hearing conservation program becomes genuinely effective.
