Vers un complément à l'audiométrie tonale pour le suivi auditif du militaire

Abstract : The auditory surveillance of military personnel exposed to noise is based on threshold tonal audiometry. Animal studies have shown that noise exposure that causes temporary threshold shifts may lead to synaptopathy between the inner hair cells and the auditory nerve. Extrapolation to humans suggests that noise exposure can lead to auditory lesions undiagnosed by threshold tonal audiometry (so called “hidden hearing loss”). However, recent studies disagree about the presence of cochlear synaptopathy in normal hearing humans. The French armed forces biomedical research institute is currently conducting studies in order to clarify this issue which could lead to a better understanding of the consequences of noise exposure and hence, update the noise exposure and protection standards. The present study was conducted among 35 normal-hearing listeners. The results show that listeners exposed for the longest time have poorer scores in consonant recognition in noise and in frequency modulation detection. Those results are consistent with noise induced cochlear synaptopathies. Nevertheless, additional data from similar ongoing studies is needed to confirm our main finding.
