The Reliability and Validity of In‐Ear Microphone Measurements of Ear Protective Devices [PDF]
The Journal of the Acoustical Society of America, 1973 A miniature microphone was placed in a subject's ear after the method described by Brammer and Piercy [J. Acoust. Soc. Amer. 52, 1972 180], and its output fed to a spectrum analyzer set to a bandwidth of 100 Hz. The subjects were seated in a semireverberant room into which a white noise field at 95 dB SPL was introduced.

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 ...

Noise Attenuation of Current Ear‐Protective Devices
The Journal of the Acoustical Society of America, 1962 Ten ear-protective devices—three plugs, three muffs, two phone-in-muff combinations, one phone-in-muff in protective helmet, and one plug-muff combination—were tested for noise attenuation. The psychophysical method of binaural threshold shift (occluded ears minus open ear) for half-octave bands of noise using three trials on five experienced listeners

Attenuation of earmuffs used simultaneously with respiratory protective devices
Medycyna Pracy, 2017 Background: In the work environment, apart from the noise, employees may be exposed to other harmful factors. Therefore, they wear hearing protectors and other personal protective equipment.

Awareness of Noise-Induced Hearing Loss Related to Exposure to High-Noise Environments—Case Study: Young Adults 18 to 30 in Greece [PDF]
Audiology ResearchBackground: Noise-induced hearing loss (NIHL) is one of the most common types of hearing impairment, even though it is preventable. However, awareness and protective behaviors among young adults remain limited.

The Journal of the Acoustical Society of America, 1956 The sound-exclusion properties (acoustic attenuation) of various earphones and ear defenders and combinations thereof were determined by the binaural, free-field, absolute-threshold-shift technique with the psychophysical method of adjustment. The earphones included dynamic earphones in two different sockets and hearing-aid-type receivers with ...

The effects of hearing protection devices on spatial awareness in complex listening environments
PLoS ONE, 2023 Hearing protection devices (HPDs) remain the first line of defense against hazardous noise exposure and noise-induced hearing loss (NIHL). Despite the increased awareness of NIHL as a major occupational health hazard, implementation of effective hearing ...
