High fidelity hearing protection devices: Attenuation in human ears and manikin devices

The Journal of the Acoustical Society of America, 2020
Flatness of attenuation was measured for high-fidelity hearing protection devices (HPDs) using microphone-in-real-ear (MIRE) and behavioral real-ear-attenuation-at-threshold (REAT) protocols. In addition, participants completed the words-in-noise (WIN) test with and without HPDs, and provided subjective ratings of perceived sound quality via surveys ...

Transfer function of open ear importance in assessment of hearing protection devices noise reduction

Russian Journal of Occupational Health and Industrial Ecology, 2021
Introduction. Objective assessment of the noise redaction (NR) of individual hearing protection devices (HDP) in industrial conditions is actual problem despite numerous studies in this direction in many countries. This study aimed to implement the F-MIRE method for measuring the NR of HDPs, considering the transfer function of the outer ear. Materials

Evaluation of Ear Protective Devices

The Journal of the Acoustical Society of America, 1956
Ear protective devices have been evaluated according to the procedures recently proposed by the American Standards Association (pure tone, binaural, free field, threshold shift method). To obtain an estimate of subject variability, attenuation values for the V-51R ear plug were determined for twenty subjects, with five replications for each subject ...

Development of an in-ear microphone for individualized measurement of hearing protection device output

The Journal of the Acoustical Society of America, 2022
Hearing protection devices (HPDs) are designed to reduce the amplitude of sound reaching the ear, but can also distort the acoustical cues necessary for sound localization. In order to quantify the acoustic impact of an HPD on the signal reaching the tympanic membrane, the signals deep in the ear canal with and without the HPD must be compared.
