Individual fit testing of hearing protection devices.
While hearing protection devices (HPD) have been the last and often only line of defense against noise-induced hearing loss in the workplace, their performance has been suspect. Laboratory evaluations have not proven to predict the actual performance of HPD in the field. Individual fit testing of HPD will allow the determination of HPD performance on individual workers, and this will improve th...
متن کاملCommunication in noise with acoustic and electronic hearing protection devices.
The purpose of the present study was to evaluate communication ability in noise at two signal presentation levels when using acoustic and electronic hearing protection devices (HPDs). Fourteen normal hearing subjects were fitted binaurally with custom acoustic HPDs (ER-15) and custom electronic HPDs (Starkey SA T9). Probe microphone measurements were obtained on 28 ears for three experimental c...
متن کاملHearing and Hearing Protection
We study the origin of the Noise-Induced Hearing Losses (NIHL) in relation to the morphology and the physiology of the ear. We describe the mechanical and metabolic effects of the noises on the inner ear and their consequences on hearing. We discuss the importance and the limitations of the protective mechanisms. Finally, we present new possibilities to protect the ear against noise and to trea...
متن کاملAn evaluation of comfort afforded by Hearing Protection Devices
This paper focused on the comfort afforded by 3 models of hearing protection devices. Devices were selected and, after being tested in a real occupational context, evaluated using a questionnaire regarding different comfort indexes. In this way, it was possible to compare the “performance” of the hearing protectors regarding the comfort indexes, and to determine which one, globally, has afforde...
متن کاملImpact of hearing protection devices on sound localization performance
Hearing Protection Devices (HPDs) can protect the ear against loud potentially damaging sounds while allowing lower-level sounds such as speech to be perceived. However, the impact of these devices on the ability to localize sound sources is not well known. To address this question, we propose two different methods: one behavioral and one dealing with acoustical measurements. For the behavioral...
