OBJECTIVES Five databases were mined to examine distributions of air-bone gaps obtained by automated and manual audiometry. Differences in distribution characteristics were examined for evidence of influences unrelated to the audibility of test signals. DESIGN The databases provided air- and bone-conduction thresholds that permitted examination of air-bone gap distributions that were free of ...

CONCLUSION These findings provide the basis for understanding the duration of the effect after the last use of the drug and encourage a larger clinical trial to collect additional evidence on the effect of coenzyme Q10 (CoQ10) in preventing the development of hearing loss in subjects with presbycusis. OBJECTIVES The aim of this study was to evaluate the long-term effects of a water-soluble fo...

OBJECTIVE To determine whether there is any influence of systemic arterial hypertension on the peripheral auditory system. METHODS This was a cross-sectional study that investigated 40 individuals between 30 and 50 years old, who were divided into groups with and without systemic arterial hypertension, using data from high-frequency audiometry, transient-evoked otoacoustic emissions and disto...

The flight crew of the Voyager aircraft were continuously exposed to a broadband noise for nearly 5 days during a trial flight, and for over 9 days during their nonstop flight around the world. Evaluation of the threshold shifts resulting from these exposures represents a unique opportunity to study the effect of human exposure to intense continuous noise for long durations. Postflight audiomet...

Some patients suffer hearing loss in the early postoperative period following vestibular schwannoma excision despite having intact hearing immediately after surgery. As this phenomenon has rarely been documented or described, the putative mechanism remains vague. The objective of the current study was to document the patterns of change in behavioural and electrophysiological responses in patien...

INTRODUCTION High-frequency audiometry may contribute to the early detection of hearing loss caused by ototoxic medications. Many ototoxic drugs are widely used in the treatment of patients with cystic fibrosis. Early detection of hearing loss should allow known harmful drugs to be identified before the damage affects speech frequencies. The damage caused by ototoxicity is irreversible, resulti...

The purpose of this study was to analyze the changes in the acoustically evoked cortical cognitive potentials N 200, P 300, and N 3 with age. There were 232 participants, who were 60 years or older, and each was examined using a battery of audiological tests including a questionnaire, otomicroscopy, pure-tone audiometry, and cortical cognitive potentials, measured at Fz using an auditory oddbal...

INTRODUCTION The present study investigated the relationship between the perceived tinnitus severity, depressive and anxiety symptoms in individuals with tinnitus. An attempt was also made to see if any relationship exists between the perceived tinnitus severity and the age, gender or hearing status of the sufferer. MATERIALS AND METHODS Fifty individuals (31 males, 19 females) with tinnitus ...
