Abstract

Auditory capacities are a given. This situation calls for efforts to adapt the work environment to the prevailing residual capacities of workers with a hearing impairment. Noise reduction is of course the first step required in order to improve signal-to-noise ratios. However, in many cases, these steps will not be sufficient to prevent performance impairment among workers with a hearing loss. Specific procedures for job accommodation are warrented. With respect to auditory warning signal detection, given a certain ambiant noise, one needs to predict the signal level at a given frequency that will meet the individual's detection capacity. Previous work has been done to adapt a laboratory procedure for measuring frequency selectivity to the constraint of a clinical test, and also to adapt Detectsound to individual rather than statistical predictions of masked thresholds. The present investigation aimed at validating such predictions among people with various degrees and configurations of sensorineural hearing loss
