BACKGROUND Hearing screening tests based on pure-tone audiometry may be conducted on mobile devices, provided that the devices are specially calibrated for the purpose. Calibration consists of determining the reference sound level and can be performed in relation to the hearing threshold of normal-hearing persons. In the case of devices provided by the manufacturer, together with bundled headph...
The ability to record from and stimulate neurons is key to our further understanding of the nervous system. Not only is it vital to many areas of research, but many clinical techniques rely on the ability to stimulate and record in the long term. Many medical devices rely upon this technology (e.g., cochlear implants that restore hearing, anti-epilepsy “pacemakers,” and artificial limbs). Howev...
Warning sound devices are commonly used in noisy workplaces to warn workers of potentially dangerous situations. Warning sound perception depends on many factors, including warning sound levels relative to the background noise, hearing protection and hearing status. Although national and international standards (i.e. ISO 7731) are available to guide the choice of warning sound devices, none app...
The purpose of this study was to record and compare audiometric pure tone thresholds of dental clinicians (DCs), dental professionals (DPs), and dental students (DSs); determine the percentage of these groups who use hearing protection devices while at work in the clinic; and measure the sound intensities generated by a few representative high-speed handpieces while they are being used on patie...
For many years, the fields of inner ear pharmacology and hearing devices have progressed in parallel with limited interaction. Recently, there has been a considerable advancement in our understanding of the inner ear and its pathologies. Cochlear implantation is now being adapted for patients with considerable residual hearing but minimal benefit from hearing aids. A major consequence is the re...
Objective: To assess the knowledge, attitude and practices of traffic policemen towards the health effects caused by noise pollution. Materials and Methods: The present questionnaire-based study was carried out among 86 traffic policemen randomly selected for an awareness workshop for prevention of noise pollution. The questionnaire included questions regarding the self assessment of the polic...
This cross-sectional study investigated noise annoyance, awareness and practice among the workers in two steel factories in UAE. The study involving 468 steel workers randomly selected. Noise exposure was estimated using the integrated sound level meter. A structured interview questionnaire was used to assess the noise annoyance, awareness and practice of workers towards the noise. The results ...
Background : Sound pollution has unwarranted effects on hearing loss. Despite numerous prior studies on sound pollution and its effects in industrial environments, scanty studies are available among musicians. The aim of the present study is to evaluate the association between musical instruments noise and hearing loss. Material and method : For this prospective study, 50 professional players o...
Background& objectives: Due to the high number of small workshops in the country, the numerous workforce of them from one hand, the existing noise as one of the harmful factors in the working environment and the importance of workers’ health from the other hand, this study was conducted with the aim of identifying the effect of training intervention of hearing protection devices use based on BA...
Hearing loss is common among older adults. Research has found a prevalence of 33% or higher of bilateral hearing loss in people 50 and older (Mitchell et al., 2011). Hearing loss has been associated with decline in both mental and physical health. Problems linked to hearing loss include lower cognitive functioning, functional status, and quality of lifefortunately, many older adults who purchas...
