In the United States and other parts of the world, recreational firearm shooting is a popular
sport that puts the hearing of the shooter at risk. Peak sound pressure levels (SPLs) from …

Noise-induced hearing loss resulting from weapon noise exposure has been studied for
decades. A summary of recent work in weapon noise signal analysis, current knowledge of …

Objective: This research assessed the reduction of peak levels, equivalent energy and
sound power of firearm suppressors. Design: The first study evaluated the effect of three …

Abstract Objective: In 2009, the US Environmental Protection Agency (EPA) proposed an
impulse noise reduction rating (NRR) for hearing protection devices based upon the impulse …

The source of an acoustic even is located. Spatial boundaries for a location are determined.
Sensing nodes are placed at the location. The intersection between a sensor area for …

To determine if conventional audiometry, EHFA, and pDPOAEs are useful as early indicators
of cochlear damage from recreational firearm impulse noise exposure in youth firearm users …

Current standards for the measurement of impulse noise (eg, MIL-STD-1474E) recommend
using a sampling rate of at least 200kHz in order to accurately estimate the risk of hearing …

Objective: This study surveyed youth recreational firearm users (YRFUs) regarding shooting
habits, reported use of hearing protection devices (HPDs), self-assessed auditory status …

Exposure to impulsive noise presents a greater risk of noise induced hearing loss than
exposure to an equivalent amount of continuous noise. Noise must be measured, recorded …

Crime scene forensic evidence may include audio gunshot recordings obtained from some
known or assumed location with respect to the shooting position. The acoustic evidence of …
