Effects 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 کاملThe Effect of Gingko Biloba on Hearing in Mice with Noise-Induced Temporary Threshold Shift
BACKGROUND AND OBJECTIVES Gingko biloba extract is known for enhancing blood circulation, scavenging free radicals, and antagonizing against platelet-activating factor. This study evaluated the effect of Gingko biloba on the noise-induced temporary threshold shift of hearing. MATERIALS AND METHODS Temporary threshold shift was induced by exposing mice to 110 dB SPL sound for 1 hour. The exper...
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...
متن کاملUnderwater temporary threshold shift in pinnipeds: effects of noise level and duration.
Behavioral psychophysical techniques were used to evaluate the residual effects of underwater noise on the hearing sensitivity of three pinnipeds: a California sea lion (Zalophus californianus), a harbor seal (Phoca vitulina), and a northern elephant seal (Mirounga angustirostris). Temporary threshold shift (TTS), defined as the difference between auditory thresholds obtained before and after n...
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...
