Sonar-induced temporary hearing loss in dolphins.
There is increasing concern that human-produced ocean noise is adversely affecting marine mammals, as several recent cetacean mass strandings may have been caused by animals' interactions with naval 'mid-frequency' sonar. However, it has yet to be empirically demonstrated how sonar could induce these strandings or cause physiological effects. In controlled experimental studies, we show that mid...
متن کاملHearing Loss in Stranded Odontocete Dolphins and Whales
The causes of dolphin and whale stranding can often be difficult to determine. Because toothed whales rely on echolocation for orientation and feeding, hearing deficits could lead to stranding. We report on the results of auditory evoked potential measurements from eight species of odontocete cetaceans that were found stranded or severely entangled in fishing gear during the period 2004 through...
متن کاملHEARING LOSS IN HEMODIALYSIS PATIENTS
Inner ear cells are sensitive to some metabolic and hormonal disorders, but the relation between chronic renal failure (CRF), regular dialysis treatment (RDT) and sensorineural hearing loss (SNHL) is still a debatable field. The object of this paper was to verify the presence of SNHL in patients submitted to hemodialysis with different duration due to CRF and in those submitted to conservat...
متن کاملTHE EFFECT OF NOISE-INDUCED HEARING LOSS ON DENTISTS
This paper presents noise problems associated with the use of air-turbine drills in dental practice. Two hundred and fifty dentists (male and female) were randomly selected from the faculty of dentistry as well as the dentists who worked private in Tehran. The results indicated that the mean value of sound pressure level produced by the high-speed drills was 69.1 db. Most of the energy from...
متن کاملAdding insult to injury: cochlear nerve degeneration after "temporary" noise-induced hearing loss.
Overexposure to intense sound can cause temporary or permanent hearing loss. Postexposure recovery of threshold sensitivity has been assumed to indicate reversal of damage to delicate mechano-sensory and neural structures of the inner ear and no persistent or delayed consequences for auditory function. Here, we show, using cochlear functional assays and confocal imaging of the inner ear in mous...
