OBJECTIVES/HYPOTHESIS Noise generated by instruments, such as mastoid or craniotomy drills, may cause hearing damage by reducing the cochlear blood flow (CoBF). This study investigated whether dexmedetomidine can lessen noise-induced hearing loss (NIHL) in a guinea pig model. STUDY DESIGN Animal study using noise stimulation and measurement of hearing and CoBF in guinea pigs. METHODS Guinea...
A review of the problems of noise induced hearing loss in children, especially related to recreational music and the use of personal entertainment devices. The patho-physiology of noise induced hearing loss, and associated problems (e.g. tinnitus) are discussed. The evidence for an increase in noise induced hearing loss in children and young people is reviewed. Some practical advice (for clinic...
Increasingly, our acoustic environment is filled with amplified sound sources (e.g., MP3 players, video game stations, and sports/entertainment venues). There is serious concern and also some controversy about the risks of acoustic trauma in children. This overview provides some basic information on the physiological mechanisms that lead to noise induced hearing loss, a survey of various studie...
BACKGROUND Tanzania has a young mining history with several operating open pit and underground mines. No prevalence studies of noise-induced hearing loss (NIHL) have been conducted among mine workers to provide an impetus for the development of comprehensive hearing protection programmes. AIMS To determine the prevalence of NIHL and associated factors among miners in a major gold mining compa...
OBJECTIVES Occupational noise-induced hearing loss (ONIHL) describes an acquired hearing deficiency directly attributable to excessive workplace noise exposure. Data suggest that excessive noise attributes to approximately 37% of all adult causes of hearing loss and remains a significant contributor to employment-related morbidity internationally. Typically insidiously-acquired, often without f...
OBJECTIVES To investigate the relation between different types of exposure to noise and a classic sign of noise induced hearing loss (NIHL), the audiometric notch. METHODS The study sample had exposure to both continuous and impulse noise and was drawn from a population of electrical transmission workers. Audiograms, taken as part of a hearing conservation programme, were read by three clinic...
BACKGROUND Noise is the most common occupational hazard. Noise-induced hearing loss (NIHL) is a known occupational disease. The economic costs of NIHL have been estimated to be billions of dollars. Besides, cigarette smoking is a common habit worldwide. METHODS In a cross-sectional study, we surveyed the effect of smoking on NIHL in 504 workers in a large wagon manufacturing company exposed t...
INTRODUCTION The purpose of this study was to evaluate noise levels in dental offices and to estimate the risk and prevalence of tinnitus and noise-induced hearing loss (NIHL) in practicing dentists. MATERIALS AND METHODS First, measures were collected of sound pressure levels produced by dental handpieces and dental suction in the University of Oklahoma Health Sciences Center (OUHSC) College...
Significance: As the use of personal listening devices has increased tremendously in the past decade, noise-induced hearing loss has become a prevalent issue in today’s medical field [1]. A prolonged listening of these devices can lead to a noise induced threshold shift, thus lowering the hearing ability of many individuals, particularly adolescents [2]. Hearing loss can have psychosocial conse...
