Introduction: From Testing to Action

When your audiometric testing day concludes, the work isn’t finished — it’s actually just beginning. The real value of testing comes from understanding the results, taking appropriate actions, and maintaining comprehensive records for ongoing compliance.

This guide explains what to expect from audiometric testing reports, how to interpret them, and how to use them effectively in your hearing conservation program.

Types of Reports Provided

The Employer Group Summary Report

This is your primary WHS document. The summary report provides an overview of the entire testing cohort and identifies action items for management.

Individual Worker Audiogram Reports

Each tested worker receives an individual report showing their personal hearing results, comparison to baseline, and any recommendations.

Digital vs. Paper Formats

Modern testing providers issue reports in both digital (PDF, secure portal) and paper formats. Digital options offer easier distribution, searchability, and secure storage. Paper reports remain important for manual records systems.

Standard Turnaround Time: 48 Hours

Why 48 Hours?

After your testing session concludes, the audiometrist needs time to:

• Complete data entry and quality assurance checks on all results
• Generate audiograms for each worker
• Compare current results to baseline data (pulling from previous testing records)
• Identify threshold shifts and other clinically significant findings
• Generate the employer summary report and individual worker reports
• Quality review of all documentation

Receiving Your Reports

Within 48 hours of your final testing session, you’ll receive:

• Employer summary report (PDF or paper)
• Individual worker reports (PDF or paper)
• Data file or portal access (if using digital system)
• Any supplementary documentation (environmental noise reports, equipment calibration confirmation)

Expedited Reporting

If you have urgent compliance needs, discuss expedited reporting with your testing provider. Some providers offer same-day or next-day summary reports for additional cost.

The Employer Summary Report: What’s Included

Report Header and Context

The summary report begins with identifying information:

• Your organisation’s name and ABN/ACN
• Testing dates and location
• Audiometrist name and qualifications
• Reference to relevant standards (AS/NZS 1269.4)

Worker List with Pass/Refer Categorization

A complete list of all workers tested, showing:

• Name and employee ID
• Date of test
• Result category: “Pass” (normal hearing, no intervention required) or “Refer” (hearing loss or threshold shift identified, audiological assessment recommended)
• Any specific findings (e.g., “Significant threshold shift at 3 kHz” or “Moderate bilateral hearing loss”)

Threshold Shift Identification

The report highlights any workers with significant threshold shifts — typically defined as 10 dB or greater change at 2, 3, or 4 kHz compared to their baseline audiogram. These workers require:

• Immediate notification
• Referral for audiological assessment
• Review of workplace controls
• Potential 2-year follow-up monitoring

Recommended Follow-Up Actions

The report will identify specific recommendations:

• Audiological assessment: Workers with hearing loss or threshold shift should be referred to an audiologist for detailed assessment and potentially hearing aid fitting or counselling
• Control measure review: If multiple workers show hearing loss or threshold shift, this suggests controls may be inadequate; review engineering controls, hearing protection, and noise monitoring
• 2-year monitoring: Workers with threshold shift are typically placed on 2-year follow-up testing to track whether hearing loss is progressing
• Worker counselling: All workers with significant findings should receive counselling about protecting their remaining hearing

Summary Statistics

The report concludes with aggregate data:

• Total workers tested
• Number and percentage with normal hearing
• Number and percentage referred for assessment
• Number and percentage with threshold shift
• No-show or incomplete test rate

Individual Worker Reports: What They Show

The Audiogram Graph

Each worker’s report includes an audiogram — a graph showing their hearing thresholds at each test frequency (500 Hz through 8000 Hz) for each ear. The vertical axis shows hearing level in decibels (dB HL), with 0 dB HL representing “normal” hearing and increasing dB representing progressively poorer hearing.

Comparison to Baseline

If a baseline audiogram exists (from previous year testing), the individual report overlays the current test with the baseline for easy visual comparison. This allows the worker to see whether their hearing has changed, improved (rare), or remained stable.

Result Category Explanation

The report explains the result in plain language:

• “Normal hearing”: Your hearing is within normal limits for your age. No action required at this time.
• “Refer for audiological assessment”: Your test result suggests hearing loss. You should see an audiologist for more detailed assessment and advice on hearing protection or hearing aids.
• “Significant threshold shift detected”: Your hearing has changed compared to your previous test. This suggests your hearing loss may be progressing. You require follow-up assessment and should ensure hearing protection is being used correctly.

Recommended Follow-Up Actions

Specific recommendations for the individual worker, which might include:

• Audiological assessment within 4 weeks
• Review of hearing protection practices
• Follow-up testing in 2 years (for threshold shift)
• Workplace accommodation (if hearing loss is affecting job performance)

Worker Information and Education

Many individual reports include educational content explaining:

• What the test measures
• What normal hearing looks like on an audiogram
• How noise causes hearing loss
• How to protect hearing at work and home
• What hearing aids are available if needed

Understanding Referrals and Significant Threshold Shift

What Triggers a “Refer” Result?

A worker is referred for audiological assessment if:

• Hearing loss is detected: Thresholds are elevated compared to normal age-matched hearing levels
• Significant threshold shift is present: 10 dB or greater change at any of 2, 3, or 4 kHz compared to baseline
• Test quality is questionable: Inconsistent responses or unusual patterns requiring specialist assessment

The AS/NZS 1269 Definition of Significant Threshold Shift

Under AS/NZS 1269, significant threshold shift is defined as:

• 10 dB or greater change at 2, 3, or 4 kHz (compared to baseline), OR
• Average shift of 10 dB or greater across three frequencies (2, 3, and 4 kHz)

This conservative definition ensures that small fluctuations (which are normal) don’t trigger unnecessary intervention, but genuine deterioration is captured.

What Does Significant Threshold Shift Mean?

It suggests accelerated hearing loss — a rate of deterioration faster than would be expected from aging alone. This could indicate:

• Inadequate hearing protection use
• Exposure to noise levels higher than anticipated
• Individual susceptibility to noise-induced hearing loss

Required Response to Threshold Shift

WHS legislation requires that if monitoring reveals significant threshold shift, you must review control measures. Under WHS Regulation 38, if a health monitoring result shows deterioration, you must review the control measures to address the risk.

How to Use the Report for WHS Compliance

Review with Your WHS Team

On receiving the report, schedule a review meeting with your WHS committee, safety manager, and occupational health advisor. Discuss:

• Overall results: What percentage of your workforce showed hearing loss or threshold shift?
• Trends: Has the situation improved, worsened, or stayed the same compared to previous years?
• Specific findings: Are threshold shifts concentrated in certain work areas or roles?
• Control measures: Do results suggest your engineering controls or hearing protection are inadequate?

Individual Worker Communication

Provide each worker with their individual report in a confidential setting. Explain the results in plain language and offer opportunity for questions. If audiological assessment is recommended, provide a referral to an audiologist and (if possible) employer support for accessing the assessment.

Referral Follow-Up

Workers referred for audiological assessment should complete this assessment within 4-6 weeks. Follow up with workers to ensure they’ve attended and received recommendations. If hearing aids are recommended and the worker accepts them, ensure comfortable fit and instruction on use.

Document the Control Review

If testing reveals hearing loss or threshold shift, document your review of control measures in your WHS records. This documentation should include:

• Review date and personnel involved
• Summary of testing results that prompted the review
• Assessment of current control measures (engineering, administrative, PPE)
• Any changes made or planned to controls
• Timeline for implementation

Update Your Risk Assessment

Use testing results to inform updates to your noise risk assessment. If testing shows:

• High prevalence of hearing loss: Re-evaluate noise levels in work areas; consider whether engineering controls need enhancement
• Pattern of threshold shifts in specific work areas: Investigate whether those areas have higher-than-expected noise levels or whether workers in those areas aren’t using hearing protection correctly
• Improving hearing health results year-on-year: Document these successes; they justify continued investment in hearing conservation

Record Management: Storage, Retention, and Access

Retention Period

AS/NZS 1269.4 requires that audiometric records be retained for at least 5 years. However, best practice is to retain records for the full duration of employment plus 5 years, particularly for workers with significant hearing loss. These records may be important for workers’ compensation claims or future liability disputes.

Secure Storage

Audiometric records contain health information and must be stored securely:

• Paper records: Locked cabinet accessible only to WHS and occupational health staff
• Digital records: Secure server with password protection and limited user access
• No shared drives: Avoid storing on general company shared drives; health data requires restricted access
• Backup: Maintain secure backups to prevent loss

Worker Access Rights

Workers have the legal right to access their own health records, including audiometric results. Establish a process for workers to request their results (confidentially, in writing) and provide them within reasonable timeframes.

Privacy Compliance

Audiometric data is personal health information and is subject to privacy legislation (Privacy Act 1988). Ensure that:

• You have clear privacy policies about how hearing data is collected, stored, and used
• Workers consent to their data being used for hearing conservation program purposes
• Data isn’t shared with third parties without worker consent
• Records are protected against unauthorized access

Frequently Asked Questions

How quickly will I receive audiometric testing reports?

The employer summary report is typically issued within 48 hours of testing completion. Individual worker reports are issued simultaneously. This allows for rapid review and follow-up action.

What information is included in the employer summary report?

The employer summary report includes: complete worker list with pass/refer categorization, identification of workers with threshold shifts or significant hearing loss, recommended follow-up actions (additional testing, audiological assessment, control measure review), and summary statistics.

What will individual worker reports show?

Individual worker reports include: the worker’s audiogram (graphical representation of hearing thresholds), comparison to baseline audiogram if applicable, result category (normal hearing or refer for assessment), recommendations for follow-up, and explanation of what the results mean.

How do I interpret a significant threshold shift?

A significant threshold shift is defined as 10 dB or greater change at 2, 3, or 4 kHz compared to baseline. This indicates potentially accelerated hearing loss and requires follow-up audiological assessment and review of workplace controls.

What action should I take if testing shows a threshold shift?

Notify the affected worker, refer them for audiological assessment, review control measures in their work area (engineering controls, hearing protection, noise levels), and update your risk assessment. Document the control review in your WHS records.

How long must I keep audiometric testing records?

Maintain audiometric testing records for at least 5 years per AS/NZS 1269.4. Consider longer retention (full employment duration plus 5 years) for workers with significant hearing loss due to potential future liability claims.

How should I store confidential hearing health records?

Audiometric records contain sensitive health information. Store in a locked cabinet or secure digital system with restricted access (WHS and occupational health personnel only). Ensure compliance with privacy legislation and health information management standards.

Can workers access their own hearing test results?

Yes, workers have the right to access their own audiometric test results. Provide individual reports in a private setting with opportunity for discussion and questions about what the results mean.

Conclusion: From Data to Action

Audiometric testing reports are far more than compliance documents — they’re actionable intelligence for protecting your workforce’s hearing health. The 48-hour turnaround allows rapid identification of workers requiring intervention and informs control measure reviews that can prevent further hearing loss.

Use your testing reports strategically: review results with your WHS team, communicate transparently with workers, follow up on referrals, and document control measure reviews. This systematic approach transforms testing from a compliance checkbox into a genuine hearing conservation program.

When you receive your reports, you have the information you need. Now ensure you take the actions those results recommend.
