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 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 کاملHuman 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 hearing threshold shift in a harbor porpoise (Phocoena phocoena) after exposure to multiple airgun sounds.
In seismic surveys, reflected sounds from airguns are used under water to detect gas and oil below the sea floor. The airguns produce broadband high-amplitude impulsive sounds, which may cause temporary or permanent threshold shifts (TTS or PTS) in cetaceans. The magnitude of the threshold shifts and the hearing frequencies at which they occur depend on factors such as the received cumulative s...
