Temporary hearing threshold shift measured by otoacoustic emissions in subjects exposed to short-term impulse noise.
OBJECTIVES The aim of the study was to assess the influence of short-term impulse noise on the size and dynamics of temporary threshold shift, which precedes permanent threshold shift, i.e. noise-induced hearing loss. It was hoped to use the findings for preventive activities. MATERIALS AND METHODS The study included 80 healthy subjects (160 ears), aged 19-23 years, divided into two groups: g...
متن کاملProtective Effects of α-Tocopherol on ABR Threshold Shift in Rabbits Exposed to Noise and Carbon Monoxide
Noise induced hearing loss (NIHL) is one of the most important occupational disease worldwide. NIHL has been found potentiate by simultaneous carbon monoxide (CO) exposure. Free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the CO hypoxia. This study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

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 کاملTemporary threshold shift in bottlenose dolphins (Tursiops truncatus) exposed to mid-frequency tones.
A behavioral response paradigm was used to measure hearing thresholds in bottlenose dolphins before and after exposure to 3 kHz tones with sound exposure levels (SELs) from 100 to 203 dB re 1 microPa2 s. Experiments were conducted in a relatively quiet pool with ambient noise levels below 55 dB re 1 microPa2/Hz at frequencies above 1 kHz. Experiments 1 and 2 featured 1-s exposures with hearing ...
