Abstract

Hearing loss has historically been mainly associated with elevated pure-tone thresholds. However, in recent years, there has been increased interest in addressing the hearing difficulties reported by individuals with normal hearing thresholds. In this study, we measured hearing thresholds, noise history, temporary threshold shift history, and hearing difficulty for a sample of 10,492 Service Members. Our data reveal that overall hearing difficulties increase systematically as a function of hearing threshold within the range that is conventionally considered to be ”normal” hearing. Noise exposure history is associated with increasing hearing difficulty at all thresholds, particularly individuals with a history of noticeable changes in their hearing after noise exposure. These results challenge some fundamental assumptions of current hearing conservation programs and suggest that variations in post-noise hearing symptoms may reflect differences in individual susceptibility to permanent damage from noise exposure.

期刊介绍： The aim of the journal is to provide a forum for papers concerned with basic peripheral and central auditory mechanisms. Emphasis is on experimental and clinical studies, but theoretical and methodological papers will also be considered. The journal publishes original research papers, review and mini- review articles, rapid communications, method/protocol and perspective articles. Papers submitted should deal with auditory anatomy, physiology, psychophysics, imaging, modeling and behavioural studies in animals and humans, as well as hearing aids and cochlear implants. Papers dealing with the vestibular system are also considered for publication. Papers on comparative aspects of hearing and on effects of drugs and environmental contaminants on hearing function will also be considered. Clinical papers will be accepted when they contribute to the understanding of normal and pathological hearing functions.
