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...

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...
