Are hearing protection devices used in the workplace really efficient? A systematic review
Work, 2022BACKGROUND: The most common current hearing protection devices (HPDs) on the market include earplugs and earmuffs. A variety of materials can be used to manufacture these devices, and each offers a level of noise attenuation that is informed by the ...

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.

Measuring the External Ear for Hearing Protection Device Design
Ergonomics in Design: The Quarterly of Human Factors Applications, 2018In this study we aimed to obtain anthropometric measurements of external ear dimensions for designing hearing protection devices (HPDs). We measured 3 dimensions of left and right ears of 153 operational workers and compared the measured data with earplugs (Eps) and earmuffs (Ems).

PurposeSensitivity to sounds and atypical reactions to sensory input by individuals with autism spectrum disorder (ASD) have been reported in the literature. In response to this sensitivity, some individuals use ear protection devices (EPDs) such as noise-canceling headphones, earplugs, or earmuffs to attenuate the perceived unpleasant sounds.

The Journal of the Acoustical Society of America, 1985
An ear protecting device for protecting a wearer from annoying and/or damaging noise levels. The device is comprised of a connecting member and a pair of muffs suitable for covering a wearer's ears. The muffs are suspended from opposite portions of the connecting member. The muffs are permeable to water vapor.

Evaluation of digital ear scanning for custom hearing protection devices
The Journal of the Acoustical Society of America, 2019Custom earpieces (e.g., hearing aids, insert hearing protection devices) are traditionally made using physical earmold impressions. Advances in technologies have led to the development of digital methods to capture ear canal geometries for the production of custom earpieces.

Variability in real-ear attenuation at threshold evaluations of hearing protection devices
The Journal of the Acoustical Society of America, 2006The American National Standard Method for the Measurement of the Real-Ear Attenuation of Hearing Protectors (ANSI S12.6-1997 [R2002]) contains explicit requirements for the physical parameters of the test facility used in measuring the performance of hearing protection devices and in subject selection and device fitting. However, the standard curiously

Fit testing of a hearing protection device with integrated in-ear noise exposure monitoring
The Journal of the Acoustical Society of America, 2018In-the-ear hearing protectors are often used in high-noise environments, such as in military operations and during weapons training. The fit of such a hearing protection device in the ear canal can cause significant variability in the noise dose experienced, an important factor in characterizing the auditory health risk.
