Exposure to Noise on Board Locomotives
AIHA Journal, 2003Personal and area noise dosimetry measurements were taken in the cabs of leading and trailing locomotives on 48 trips, under winter and summer conditions, on 9 different routes. The mean equivalent sound level (L(EQ), 3 dB exchange rate, 50 dBA threshold) of the engineers and conductors was 84 dBA during winter and 88 dBA during summer.

Noise Exposure of Music Teachers
Journal of Occupational and Environmental Hygiene, 2004A noise exposure survey was performed to assess the risk of hearing loss to school music teachers during the course of their activities. Noise exposure of 18 teachers from 15 schools was measured using noise dosimeters. The equivalent continuous noise level (L(eq)) of each teacher was recorded during single activities (classes) as well as for the ...

The Journal of the Acoustical Society of America, 1967
A simple method for determining permissible noise exposures has been developed from the NAS-NRC CHABA report [Kryter, Ward, Miller, and Eldredge, J. Acoust. Soc. Am. 39, 451–464 (1966)]. The data of this report imply that the susceptibility of the ear to noise injury varies with frequency in the same manner for steady, varying, and interrupted noise ...

Noise Exposure May Diminish the Musician Advantage for Perceiving Speech in Noise.
Ear and Hearing, 2018OBJECTIVE Although numerous studies have shown that musicians have better speech perception in noise (SPIN) compared to nonmusicians, other studies have not replicated the "musician advantage for SPIN." One factor that has not been adequately addressed ...

Safe Level for Noise Exposure?
Annals of Otology, Rhinology & Laryngology, 1976The safety of long, continuous exposure to several different levels of noise was determined. Chinchillas were exposed for two or nine days to an octave band of noise with a center frequency of .5 kHz or 4 kHz. By examining the inner ear for evidence of acute cellular degeneration, exposures which produced minimal permanent damage could be identified ...

Interaction of kanamycin and noise exposure
The Journal of Laryngology & Otology, 1979The amount of hair cell damage in the cochleas of guinea pigs after exposure to different experimental conditions suggests that a 'safe' level of kanamycin has a potentiating effect on damage due to noise. Such an effect lasts more than 20 days after the cessation of the drug administration.
