The existing speech corpora are of limited value in assessing the combined effects of hearing loss, hearing protection, and noise on speech intelligibility in the work place. One reason for this is the differences between the acoustic characteristics

Five insert-type hearing protectors (three viscose foam, one multiflanged, and one glass fiber) were evaluated for lateral drift in the ear canal as a result of 30 min of controlled jaw movement. The lateral drift was compared to changes in attenuati

A total of 262 noise spectra were divided empirically into three groups and the accuracy of the NRR estimate of hearing protector attenuation was evaluated for each group using 15 hearing protectors. The mean and the standard deviation of the error i

An assumption was made that a hearing protector (HP) attenuation function derived from some combination of the A-weights and C-weights used in the calculation of the NRR would produce a minimum difference between the NIOSH long R-value and the NRR-dB

Samples of five insert-type hearing protectors (three viscose foam, one poly-flanged, and one glass fiber) were evaluated for change in attenuation as a result of 30 min of controlled jaw movement. Protected-ear, narrow-band noise thresholds were obt
