Human temporary threshold shift (TTS) and damage risk.
Information regarding the relation of human temporary threshold shift (TTS) to properties of steady-state and intermittent noise published since the 1966 appearance of the CHABA damage risk contours is reviewed. The review focuses on results from four investigative areas relevant to potential revision of the CHABA contours including effects of long-duration exposure and asymptotic threshold shi...
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 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 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 کاملValidity of a temporary threshold shift (TTS) detector for use with portable listening devices
Recent studies on the use of portable audio listening devices indicate that while sustained listening at the maximum output volume of the unit is potentially hazardous with most devices, personal habits and listening preferences during actual use are such that only a 5-10% fraction of users may be at high risk of developing permanent hearing damage. Given the explosive increase in sales for the...
