Definition and legal context
In New York, traumatic hearing loss is defined as a sudden, measurable decline in hearing ability caused by a workplace incident, such as an explosion, gunshot, or high‑decibel impact. The Workers' Compensation Law treats it as a compensable injury when the loss is documented and linked to employment, triggering medical evaluation, benefit eligibility, and potential permanent disability awards.

Standard audiometric tests
The primary tool for quantifying loss is pure‑tone audiometry. An audiologist measures air‑ and bone‑conduction thresholds at frequencies from 250 Hz to 8 kHz for each ear. The results are plotted on an audiogram, which serves as the legal record of the injury. Baseline tests—usually performed at hire or within 30 days of a reported incident—provide the pre‑injury reference point required for comparison.
Calculating the degree of loss
New York follows the American Medical Association's (AMA) Guidelines for Occupational Hearing Loss. The calculation uses the average threshold shift at 500, 1000, 2000, and 3000 Hz (the "speech frequencies"). The formula is:
Degree of loss = (Post‑injury average – Pre‑injury average) × 2
Multiplying by two accounts for the bilateral nature of most workplace noise exposures. If the result exceeds a 10‑dB loss, the injury is considered compensable.
Documentation requirements
To support a claim, the following documents must be submitted:
- Baseline audiogram (if available)
- Post‑injury audiogram performed within 30 days of the incident
- Medical report linking the acoustic trauma to the work event
- Employer's incident report and any safety investigation findings
Missing any of these items can delay or jeopardize claim approval.
Permanent disability rating
If the hearing loss is deemed permanent, the NY Workers' Compensation Board assigns a disability rating based on the calculated loss. The rating ranges from 0 % to 100 % and determines the lump‑sum compensation for permanent total disability (PTD) or partial disability (PPD). The rating table is:
| Loss (dB) | Disability % | Compensation |
|---|---|---|
| 10‑19 | 10‑20 | Partial |
| 20‑29 | 21‑30 | Partial |
| 30‑39 | 31‑40 | Partial |
| 40‑49 | 41‑50 | Partial |
| 50+ | 51‑100 | Partial or PTD |
Ratings above 50 % may qualify for permanent total disability benefits, which include ongoing wage replacement and medical coverage.
Appeals and disputes
If an employer or insurer disputes the loss calculation, the claimant can request a hearing before the Workers' Compensation Board. An independent audiologist may be appointed to re‑evaluate the audiograms. The board's decision is final unless appealed to the Appellate Division.
Practical tips for claimants
• Schedule the post‑injury audiogram as soon as possible—delays can be interpreted as non‑compliance.• Keep copies of all incident reports, safety logs, and medical records.• Seek a qualified audiologist familiar with NY workers' compensation standards.• Consult a workers' compensation attorney early to ensure proper filing and representation.
