Temporary threshold shift of temperature sensation caused by vibration exposure.
The temporary threshold shift of temperature sensation due to vibration exposure was studied to clarify the significance of frequency and acceleration on it. The discrete frequencies of the vibrations tested were 32, 63, 125, 250 and 500 Hz, and the accelerations were at the level of 2, 4, 8 and 16 g. The threshold shift of warm sensation (TTSw) was markedly, but that of cool sensation was smal...
متن کاملEffects of magnesium on temporary threshold shift
Casey, Sarah, Audiology Doctoral Project, University of South Florida, July, 2003. Effects of Magnesium on Temporary Threshold Shift. Previous literature has demonstrated that supplemental magnesium may have a prophylactic effect on noise induced hearing loss (NIHL). The purpose of this study was to replicate the findings of a previous investigation concerning the beneficial effects of suppleme...
متن کاملTemporary threshold shift of vibratory sensation induced by a vibrating handle and its gripping force.
OBJECTIVE This study examines the effect of the force with which a vibrating handle is gripped on the temporary threshold shift of vibratory sensation (TTSv) induced by hand-arm vibration. METHODS Six healthy subjects gripped a handle vibrating with a 1.3 octave-band vibration, with a central frequency of 200 Hz and an intensity of 39.2 m/s2. Exposure was for 1 min and 10 min, respectively. G...
متن کاملUnderwater temporary threshold shift induced by octave-band noise in three species of pinniped.
Pure-tone sound detection thresholds were obtained in water for one harbor seal (Phoca vitulina), two California sea lions (Zalophus californianus), and one northern elephant seal (Mirounga angustirostris) before and immediately following exposure to octave-band noise. Additional thresholds were obtained following a 24-h recovery period. Test frequencies ranged from 100 Hz to 2000 Hz and octave...
متن کاملtemporary threshold shift and noise-induced hearing handicap in a group of textile workers
exposing the ear to an intense noise will probably cause to hearing loss. this loss may be temporary threshold shift (tts), permanent threshold shift (pts), or a combination of the two. the average audiograms for the 157 textile workers, exposed to an average 100 db (a) overall noise level, in 5 age groups indicated that the losses were most prominent for frequencies of 3 to 6 kc/s showing a pe...
