A method for allocation of hearing handicap
1Department of Otolaryngology-Head and Neck Surgery, University of Washington, Seattle 98195.
Summary
A new three-stage method accurately allocates hearing handicap. This approach calculates hearing loss per ear based on injury or noise exposure, ensuring fair compensation for hearing impairment.
Area of Science:
- Audiology
- Occupational Health
- Forensic Medicine
Background:
- Establishing fair compensation for hearing handicap requires accurate methods.
- Existing methods may not adequately account for age-related hearing changes or bilateral hearing loss.
Observation:
- Hearing loss allocation is complex, involving injury/noise exposure, age correction, and bilateral distribution.
- The 1979 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) and American Medical Association (AMA) standard provides a basis for handicap division.
Findings:
- A three-stage method is proposed for hearing handicap allocation.
- Stage 1 calculates ear-specific hearing loss percentage using hearing change (post-age correction) relative to final hearing level.
- Stage 2 divides the final hearing handicap between ears using an established formula; Stage 3 multiplies the scores from Stages 1 and 2 for period-specific, ear-allocable hearing handicap.
Implications:
- This method offers a standardized, objective approach to calculating hearing handicap for compensation or legal purposes.
- Accurate allocation can improve fairness in disability claims related to noise-induced hearing loss.
- The method provides a clear framework for audiologists and legal professionals assessing hearing impairment.
