Hearing-impaired listeners with similar hearing losses may differ widely in their ability to understand speech in noise. Such individual susceptibility to noise may explain why patients obtain varying degrees of benefit from hearing aids. The chief purpose of this study was to determine if adaptive measures of unaided speech recognition in noise were related to hearing aid benefit. Additionally...

background: in dental practical classes, the acoustic environment is characterized by high noise levels in relation to other teaching areas. the aims of this study were to measure noise levels produced during the different dental learning clinics, by equipments used in dental learning areas under different working conditions and by used and brand new handpieces under different working condition...

PURPOSE Noise exposure is an important and highly prevalent occupational hazard in the construction industry. This study examines hearing threshold levels of a large population of Dutch construction workers and compares their hearing thresholds to those predicted by ISO-1999. METHODS In this retrospective study, medical records of periodic occupational health examinations of 29,644 constructi...

noise is one of the major hazardous occupational exposures and one of the occupations at risk is the transportation industry. however, few studies have measured and reported the amount of noise exposure in drivers. in this study, we evaluated noise exposure among the public transportation bus drivers of one major iranian city, kerman, southeast iran. eighty public transportation buses in the st...

conclusions according to the results, hearing impairment in high frequency sounds was more common in the diabetics than the healthy individuals. also, the severity of hearing loss in patients with diabetes was associated with the levels of creatinine (diabetic nephropathy). the hypothesis of the relationship between diabetes and hearing loss through nephropathy should be more examined in future...

background: one of the most common complaints expressed by individuals with hearing-impairment is the difficulty in speech perception in background noise. different tests have been developed for the evaluation of reduced ability of speech perception in noise, and the consonant-vowel in noise test is one of the simplest one regard to speech materials. the goal of the present study was developmen...
