Fit testing of a hearing protection device with integrated in-ear noise exposure monitoring

The Journal of the Acoustical Society of America, 2018
In-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.

On the Behavior of Ear Protection Devices below 1000 cps

The Journal of the Acoustical Society of America, 1958
An extensive set of measurements has been made on various type of ear protection devices, generally consisting of a hard-shelled volume coupled to the head by an annular pad filled with various materials. Attenuation measurements were made with a miniature pressure microphone.

Evaluation of level-dependent performance of in-ear hearing protection devices using an enclosed sound source

The Journal of the Acoustical Society of America, 2014
Hearing protection devices are increasingly designed with the capability to protect against impulsive sound. Current methods used to test protection from impulsive noise, such as blasts and gunshots, suffer from various drawbacks and complex, manual experimental procedures.

Occlusion effects of hearing protection device on ear canal transfer function and cochlear injury from impulse noise exposure

The Journal of the Acoustical Society of America, 2018
The objective of this paper is to present a new finding on the effects of hearing protection devices (HPDs) on the ear canal (EC) transfer function (TFEC2ED). Specifically, we show that when an earmuff is worn, the TFEC2ED is not the same as that for the bare head, leading to a significant difference in cochlear injury prediction.

Experimental Evaluation of Blast Loadings on the Ear and Head with and Without Hearing Protection Devices

This work will describe the experimental evaluation of blast loadings on post mortem human surrogates instrumented to obtain pressure and strain measurements at various locations as a precursor to studies on biological models to investigate neurological damage to the auditory cortex.
