Background & Aims of the Study: Among the environmental pollutions, noise pollution, due to the potential physiological and psychological effects on humans, is of a particular importance. Exposure to noise can result in hearing loss in citizens. Health risks from noise associated with road traffic. Noise health effects are the health consequences of elevated sound levels. This ...
BACKGROUND Noise-induced hearing loss is a major cause of deafness and hearing impairment in the United States. Though genetics and advanced age are major risk factors, temporary and permanent hearing impairments are becoming more common among young adults and children especially with the increased exposure to portable music players. Though treatment options are limited for most people with noi...
Hearing aids are devices used by hearing impaired people to compensate hearing losses. Digital hearing aids are better in performance over the analog hearing aids, since analog hearing aids work as amplifier. Digital hearing aids are programmable to adjust the gain value, enhance signal to noise ratio, reduction in noise, feedback cancellation etc . In the present work, study of digital hearing...
Background: The damaging effect of exposure to loud noise on the structures of internal ear has been studied from many years ago. The effect of drill-generated noise on the non-operated ear is one of the problems that are less discussed. This study aims to evaluate the hearing loss that occurs in the non-operated ear in patients who undergo mastoidectomy by use of PTA (pure tone audiometery) an...
In this study, the performance of 48 listeners with normal hearing was compared to the performance of 46 listeners with documented hearing loss. Various conditions of directional and omnidirectional hearing aid use were studied. The results indicated that when the noise around a listener was stationary, a first- or second-order directional microphone allowed a group of hearing-impaired listener...
BACKGROUND Healthy hearing depends on sensitive ears and adequate brain processing. Essential aspects of both hearing and cognition decline with advancing age, but it is largely unknown how one influences the other. The current standard measure of hearing, the pure-tone audiogram is not very cognitively demanding and does not predict well the most important yet challenging use of hearing, liste...
background: noise pollution has a particular importance in quiet environments such as hospitals. the main objective of this study was to evaluate the effects of noise exposure on the auditory system, blood pressure and precision, concentration and other psycho-neural components. methods: this cross-sectional study was carried out in three large hospitals of shiraz, during the period of 2012 to ...
AIMS To survey current, Danish industrial noise levels and the use of hearing protection devices (HPD) over a 10-year period and to characterise the association between occupational noise and hearing threshold shift in the same period. Furthermore, the risk of hearing loss among the baseline and the follow-up populations according to first year of occupational noise exposure is evaluated. MAT...
