Abstract 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 suppressors at four microphone positions around four firearms. The second study assessed the suppressor-related reduction of sound power with a 3 m hemispherical microphone array for two firearms. Results: The suppressors reduced exposures at the ear between 17 and 24 dB peak sound pressure level and reduced the… 

Selection of Level-Dependent Hearing Protectors for Use in An Indoor Shooting Range

Depending on the assessment criterion adopted, a sufficient reduction in impulse noise was provided by either four or six out of the 10 hearing protectors included in the study.

Force and Sound Pressure Sensors Used for Modeling the Impact of the Firearm with a Suppressor

A mathematical model for projectiles shooting in any direction based on sensors distributed stereoscopically is put forward, based on the characteristics of a shock wave around a supersonic projectile and acoustical localization, which shows an increase in silencers chamber volume results in a reduction of recorded pressure within the silencer chamber.

Numerical and Experimental Analysis of Sound Suppressor for a 5 . 56 mm

A sound suppressor is an internal or external device coupled to the barrel of a firearm. Its development has been historically related to the negative effects produced by the noise. This article

Impulse noise measurement in view of noise hazard assessment and use of hearing protectors.

Experience shows the occurrence of situations when the measurements of impulse noise parameters are made with measurement equipment unsuitable for such conditions. The results of using such equipment

Cohort difference in the association between use of recreational firearms and hearing loss: findings from the HUNT study.

Analyses of two cohorts revealed a reduction in the association between recreational firearm use and hearing over 20 years, coinciding with the introduction of hearing preservation measures.

Cumulative noise exposure model for outdoor shooting ranges.

An impulsive noise exposure model for outdoor military shooting ranges was created and can predict and assess total exposures and protection measures for shooters, instructors, and other range personnel.

Noise-induced hearing loss and its prevention: Integration of data from animal models and human clinical trials.

Study design considerations for NIHL otoprotection in pre-clinical and clinical testing are integrated and broadly discussed with evidence-based guidance offered where possible, drawing on the contributions to this special issue as well as other existing literature.

Systematic Review of Interventions to Prevent Occupational Noise-Induced Hearing Loss - A Follow-up.

A systematic review of the effectiveness of interventions to prevent occupational hearing loss concluded that as intervenções utilizadas resultaram em efeitos positivos sobre a audição e/ou so about a exposição ao ruído.

Toward an improved hearing safety standard for impulse noise exposure in the Canadian Armed Forces

Introduction: Current hearing safety standards for the Canadian Armed Forces (CAF) do not adequately address exposure limits for mitigation of noise-induced hearing loss (NIHL) from weapon noise. R...

Difficult-to-Treat Resistance in Gram-negative Bacteremia at 173 US Hospitals: Retrospective Cohort Analysis of Prevalence, Predictors, and Outcome of Resistance to All First-line Agents

Nonsusceptibility to first-line antibiotics is associated with decreased survival in GNBSIs and DTR is a simple bedside prognostic measure of treatment-limiting coresistance.



Noise exposure profiles for small-caliber firearms from 1.5 to 6 meters

Small caliber firearms (rifles, pistols and shotguns) are commonly used at outdoor firing ranges for training in shooting skills, job qualification and for recreation. Firearm noise from fifty-four

Hearing loss and handicap of professional soldiers exposed to gunfire noise.

The prevalence of hearing loss in the Finnish Defence Forces seems to have decreased, but a fairly large number of younger men still suffer considerable hearing loss and disabling tinnitus, although the use of hearing protectors has substantially increased during the past 15 years.

Measuring recreational firearm noise.

Recreational use of firearms in the United States is commonplace. There are 28 × 106 Americans who consider themselves hunters and 13 × 106 went hunting in 2000. Participation in the shooting sports,

Spectral analysis of hearing protector impulsive insertion loss

IPIL depends strongly on the source used to measure them, especially for HPDs with less attenuation at low frequencies, but ISIL provides an alternative measurement of impulse protection and appears to be a more complete description of an HPD's performance.

An Interim LAeq8 Criterion for Impulse Noise Injury.

A method to account for the effects of the hearing protection devices (HPDs) for use with the 8 hours equivalent A-weighted energy (LAeq8) criterion shows that L(95,95) is 89 dBA, which is slightly higher than the 85 dBA criterion but falls in the 80 to 90 dBA range as used by various NATO nations.

Hearing loss and hearing handicap in users of recreational firearms.

Audiometric and HHIA-S results revealed that both high-frequency hearing loss and hearing handicap varied significantly as functions of age and occupation, with correlation coefficients highest for pure-tone methods that do not employ 500 Hz in the calculation.

Shooting habits of U.S. waterfowl hunters.

Waterfowl hunters in this study typically used large bore semiautomatic shotguns, did not consistently utilize HPDs during target practice or hunting and were exposed to multiple, unprotected shots during the past waterfowl season.

Spectral analysis of impulse noise for hearing conservation purposes.

Generalized spectral methods have been evaluated by means of an impulse simulation applied to a mathematical model of the human hearing mechanism and the results fully support the proposed rating methods.

Insights into hazard from intense impulses from a mathematical model of the ear.

Time and frequency domain mathematical models of the ear including significant nonlinearities in the middle ear were developed to trace energy flow from the free field to the inner ear and ultimately allow the calculation of basilar membrane displacement and a consequent hazard function.

Acoustic reflexes are common but not pervasive: evidence from the National Health and Nutrition Examination Survey, 1999–2012

Acoustic reflexes are not sufficiently prevalent to be included in DRC and HHA for impulsive noise and might be invoked in damage-risk criteria (DRC) and health hazard assessments (HHA) forImpulsive noise.
