How this affects your claim in practice
In a tinnitus claim, the diagnosis is only the starting point. The records should connect contemporaneous GP, audiology or ENT records documenting onset, laterality, persistence and associated hearing symptoms and audiograms and ear examination to identify any accompanying hearing loss or another condition with the worker's practical limits, including concentration, sleep-related fatigue, communication and tolerance of quiet or noisy settings and whether symptoms affect reliable safety-critical attention, supported by contemporaneous records. If the insurer disputes whether tinnitus began with the work exposure or another cause, the response should address that reason directly.
Assessment source
- NSW Guidelines for the Evaluation of Permanent Impairment, paras 1.8-1.12: NSW Guidelines control the assessment method and AMA5 is used only where adopted and not modified.
- NSW Guidelines para 1.12: AMA5 Chapter 18 pain is excluded; chronic pain is assessed through the underlying diagnosed condition, while CRPS is assessed under the relevant NSW method.
- NSW Guidelines para 1.15: assessment should usually wait until maximum medical improvement, meaning the condition is stable and unlikely to change substantially in the next year.
- NSW Guidelines Chapter 9, paras 9.1-9.16 and Table 9.1: a medical specialist assesses stable hearing loss using the National Acoustic Laboratories Report No. 118 method, then converts adjusted binaural hearing impairment (BHI) to WPI.
- NSW Guidelines para 9.11: a medical specialist may add up to 5% BHI for severe work-related tinnitus after any presbyacusis correction and before conversion through Table 9.1. Tinnitus is not a separate automatic WPI value.
Occupational conditions and exposure patterns
Tinnitus is a perceived ringing, buzzing, humming or other sound without a corresponding external source. It may be unilateral, bilateral, intermittent or persistent.
- It may follow sudden acoustic trauma, cumulative noise exposure, head or ear injury, medication or another ear condition.
- Tinnitus can coexist with hearing loss, but one does not prove the other and they should not be double-counted.
Symptoms and findings that matter
There is no direct objective test that measures the reported sound. The clinician records onset, laterality, persistence, associated hearing findings and whether the history remains consistent over time.
Audiometry and ear examination help identify accompanying hearing loss or another condition rather than assigning a value from symptom severity alone.
Sleep, concentration and communication effects may explain practical impact, but they do not themselves select a WPI row.
What investigations are usually relevant
Investigations for tinnitus may include contemporaneous GP, audiology and ENT records documenting onset and course and audiograms and relevant ear examination findings. Each result should answer a defined clinical question and be read with the examination, diagnosis and history.
- A dated occupational noise or acoustic-incident history.
- Medication and other medical history where competing causes are relevant.
How WPI is assessed for this body part
Tinnitus is not converted into a stand-alone WPI percentage from a symptom score or narrative description.
Under NSW paragraph 9.11, a medical specialist may add up to 5% BHI where severe tinnitus results from a work-related injury. The addition is made after any presbyacusis correction and before adjusted BHI is converted to WPI through Table 9.1.
Mild tinnitus does not produce the addition. The medical report should explain severity, persistence, work relationship and accompanying audiometric findings rather than assume the maximum allowance.

Worked assessment illustrations
These examples paraphrase the assessment reasoning in the source material. They explain method only and are not predicted outcomes.
Illustration 1
Tinnitus is considered before the BHI-to-WPI conversion
Assumed facts: Assume valid audiometry produces 20.1% BHI after the applicable deduction and a medical specialist supports a 4% BHI allowance for severe work-related tinnitus.
Method: The adjusted figure is 24.1% BHI. NSW Table 9.1 then converts 24.1% BHI to 12% WPI; the 4% tinnitus allowance is not described as 4% WPI.
Illustrative outcome: The allowance can be lower or absent depending on the medical evidence. This paraphrased illustration is not an estimate for the reader.

What usually does not increase WPI
Ringing after a noisy shift does not by itself establish permanent impairment.
Sleep or concentration difficulty is not an automatic hearing WPI addition.
A normal or near-normal audiogram does not prove or disprove tinnitus, but it does prevent the page from treating tinnitus as measured hearing loss.
Evidence checklist
The records for tinnitus should include records close to onset describing the tinnitus and exposure or incident and current audiology and ENT material, including associated hearing findings. They are most useful when the diagnosis, examination and practical restrictions are consistent.
- Noise-exposure chronology and relevant hearing-protection records.
- The current NSW rule relied on for any proposed numerical assessment.
How this injury commonly happens at work
Work-related tinnitus can arise through a sudden acoustic event followed by ringing, buzzing or another perceived sound and gradual occupational noise exposure where tinnitus arises with or without measured hearing loss. The chronology should identify the actual task or event and when symptoms or function changed.
Work-related tinnitus can arise through an accepted head, ear or medication-related event requiring medical differentiation. The chronology should record the actual task or event and the point at which symptoms or function changed.
Common insurer disputes
For tinnitus, an insurer may dispute whether tinnitus began with the work exposure or another cause and whether the report is persistent and clinically credible despite having no direct objective measurement. The written decision should be answered with evidence directed to those reasons.
Further disputes about tinnitus may concern whether tinnitus is being confused with or double-counted as hearing loss and whether a claimed percentage has been quoted without the controlling NSW criteria. The decision notice should identify which issue is relied on and the evidence said to support it.
Treatment and surgery issues
Depending on the diagnosis and treating opinion, management of tinnitus may involve audiology or ENT review, hearing or sound-management strategies and sleep support where clinically appropriate and review of workplace noise exposure and hearing protection. The request should explain the expected functional benefit and its connection to the accepted injury.
Weekly payments and work capacity
Capacity evidence for tinnitus should address concentration, sleep-related fatigue, communication and tolerance of quiet or noisy settings and whether symptoms affect reliable safety-critical attention, supported by contemporaneous records. Proposed duties must be sustainable for the proposed hours, not merely possible once.
For tinnitus, capacity evidence should address practical controls that may assist without assuming permanent incapacity. The question is whether those activities can be performed safely, reliably and for the proposed hours—not whether a task can be attempted once.
How NSW Work Injury Claim can help
For tinnitus, a claim review can help to document the onset and course of tinnitus with the exposure history and obtain the appropriate audiology or ENT assessment. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
For tinnitus, a claim review can help to prevent tinnitus, hearing loss and work-capacity effects from being conflated. The purpose is to identify the precise decision and the evidence needed for the next available step, not to promise an outcome.
Common questions about tinnitus claims
How can work cause or aggravate tinnitus?
For tinnitus, the relevant work history may include a sudden acoustic event followed by ringing, buzzing or another perceived sound, gradual occupational noise exposure where tinnitus arises with or without measured hearing loss, and an accepted head, ear or medication-related event requiring medical differentiation. A claim still depends on the actual chronology and medical evidence. The records should identify what changed, when symptoms began or worsened, and how the diagnosed condition affects the worker's duties.
How is WPI assessed for tinnitus?
For tinnitus, tinnitus is not converted into a stand-alone WPI percentage from a symptom score or narrative description. There is no direct objective test that measures the reported sound. The clinician records onset, laterality, persistence, associated hearing findings and whether the history remains consistent over time. The assessor must apply the NSW Guidelines to the accepted, stable condition; the diagnosis or an operation does not by itself determine a percentage.
Which records are most useful for a tinnitus assessment?
A tinnitus assessment commonly needs records close to onset describing the tinnitus and exposure or incident, current audiology and ENT material, including associated hearing findings, noise-exposure chronology and relevant hearing-protection records, and the current NSW rule relied on for any proposed numerical assessment. Those records are most useful when they describe the same diagnosis, examination findings, treatment history and practical work restrictions.
What does an insurer commonly dispute about tinnitus?
For tinnitus, common issues include whether tinnitus began with the work exposure or another cause, whether the report is persistent and clinically credible despite having no direct objective measurement, and whether tinnitus is being confused with or double-counted as hearing loss. The response should address the insurer's stated reason with the relevant chronology, clinical findings, investigations and duties evidence rather than relying on the diagnosis alone.
How can tinnitus affect weekly payments and suitable duties?
Capacity evidence for tinnitus may need to address concentration, sleep-related fatigue, communication and tolerance of quiet or noisy settings, whether symptoms affect reliable safety-critical attention, supported by contemporaneous records, and practical controls that may assist without assuming permanent incapacity. A certificate should describe what the worker can do safely and sustainably. Proposed duties should then be checked against those restrictions and the real demands of the job.
Does tinnitus automatically receive a fixed WPI percentage?
No. For tinnitus, one verified example is severe work-related tinnitus: Up to 5% BHI, under NSW Guidelines para 9.11. That value applies only when its stated criteria are met. Ringing after a noisy shift does not by itself establish permanent impairment.
