Model for Estimating Noise-Induced Hearing Loss Associated With Occupational Noise Exposure in a Specified US Navy Population

Abstract

This report details the initial steps in the development of a method for modeling the noise-induced hearing loss accrued by a population of Sailors exposed to high-level steady-state occupational noise. The model is based on the predictive algorithm described in ANSI S3.44-1996. "Determination of Occupational Noise Exposure and Estimation of Noise-Induced Hearing Impairment." For the purpose of developing the model. a specific population of Sailors is described which meets many of the criteria for the application of the S3.44 algorithm. Next, the predicted distributions of hearing threshold levels associated with age and noise for this population are calculated using the S3.44 algorithm, and these predicted distributions are compared with the distributions of actual hearing threshold levels of the group. Connections to the input values of the S3.44 algorithm are proposed based on a maximum likelihood curve-fitting procedure. Finally. recommendations are provided for the purposes of refining the model and improving its generalizability to other noise-exposed populations.
