This study evaluates speech discrimination ability, as determined by a standard test of speech reception in noise, for one type hearing defect commonly found in military personnel, namely, noise-induced high-frequency hearing loss. Enlisted submariners with high-frequency hearing loss (average of 22, 45 and 60 decibels at 3, 4 and 6 kiloHertz, respectively) had poorer scores than a normal-heari...
Congenital hearing loss is estimated to affect one in every 1,000 newborns. Causes of hearing loss can be conductive, sensorineural, mixed, or central. Known risk factors for congenital hearing loss include cytomegalovirus infection and premature birth necessitating a stay in the neonatal intensive care unit. However, up to 42 percent of profoundly hearing-impaired children will be missed using...
This study characterized the profile of pragmatic abilities among 24 children with hearing loss (HL) aged 6.3-9.4 years, 13 using hearing aids (HAs) and 11 using cochlear implants (CIs), in comparison to those of 13 hearing children with similar chronological and language ages. All the children with HL used spoken language, attended regular schools, and received communication therapy twice a we...
Introduction: Noise is considered as a physical hazard that seriously threatens human health in industrial environments. It is also the most important and influential harmful physical factor in workplace that can affect the individuals’ lifestyle and job. The present study aimed to determine the effects of chronic noise on the hearing ability as well as psychological and mental attitudes of wor...
OBJECTIVE Results of objective clinical tests (e.g., measures of speech understanding in noise) often conflict with subjective reports of hearing aid benefit and satisfaction. The Performance-Perceptual Test (PPT) is an outcome measure in which objective and subjective evaluations are made by using the same test materials, testing format, and unit of measurement (signal-to-noise ratio, S/N), pe...
BACKGROUND Little is known about quality of life after the use of specific types of hearing aids, so it is difficult to determine whether technologies such as programmable circuits and directional microphones are worth the added expense. OBJECTIVE To compare the effectiveness of an assistive listening device, a nonprogrammable nondirectional microphone hearing aid, with that of a programmable...
Hearing function is known to be heritable, but few significant and reproducible associations of genetic variants have been identified to date in the adult population. In this study, genome-wide association results of hearing function from the G-EAR consortium and TwinsUK were used for meta-analysis. Hearing ability in eight population samples of Northern and Southern European ancestry (n = 4591...
