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 کاملIndividual Fit Testing of Hearing Protection Devices Based on Microphone in Real Ear
Background Labeled noise reduction (NR) data presented by manufacturers are considered one of the main challenging issues for occupational experts in employing hearing protection devices (HPDs). This study aimed to determine the actual NR data of typical HPDs using the objective fit testing method with a microphone in real ear (MIRE) method. Methods Five available commercially earmuff protect...
متن کاملThe Viability of Hearing Protection Device Fit-Testing at Navy and Marine Corps Accession Points
INTRODUCTION The viability of hearing protection device (HPD) verification (i.e., fit-testing) on a large scale was investigated to address this gap in a military accession environment. MATERIALS AND METHODS Personal Attenuation Ratings (PARs) following self-fitted (SELF-Fit) HPDs were acquired from 320 US Marine Corps training recruits (87.5% male, 12.5% female) across four test protocols (1...
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...
