the mean noise levels were measured in the different sections of six representative mills in the isfahan area, and audiometric measurements were made in 282 male workers employed in these mills. the mean noise levels were on average 95 dba in the weaving sections and 88 d ba in the spinning sections. the audiometric findings showed a significant loss of gearing in the textile workers as compare...

BACKGROUND Different mechanisms have been proposed to be involved in tinnitus generation, among them reduced lateral inhibition and homeostatic plasticity. On a perceptual level these different mechanisms should be reflected by the relationship between the individual audiometric slope and the perceived tinnitus pitch. Whereas some studies found the tinnitus pitch corresponding to the maximum he...

UNLABELLED Hearing loss in the elderly is one of the most incapacitating communication disorders, preventing them to fully perform their tasks in society. AIM This study aimed to determine what is the best tool that together with the audiometric tests better represents the hearing loss reported by the elderly and which frequencies in the audiometric test must be considered to determine the he...

Audiometric criteria establishing the ototoxic effects of cisplatin (CDDP) vary widely in the literature. Normal test-retest variability in audiometric thresholds resulting from serial audiometry is likely a confounding variable in the over-reporting of ototoxic effects. This study investigated the variability of serial audiometry for a group of 21 head and neck cancer patients receiving no kno...
