results the mean age and work experience of workers were 31.39 ± 5.6 and 4.35 ± 2.5 years, respectively. among the exposed-to-noise personnel, 7.35% used hpds constantly; 75% used hpds for only short periods of time (less than four hours) and 17.65% did not make use of them at all. regarding the sound intensity and the level of noise reduction of hpds, among the 112 workers who used such device...

background: noise-induced hearing loss (nihl) is one of the most common occupational diseases and the second most common cause of workers' claims for occupational injuries. objective: due to high prevalence of nihl and several reports of improper use of hearing protective devices (hpds), we conducted this study to compare the effect of face-to-face training in effective use of earplugs with app...

In EARLogs1 #1 and #2 we have demonstrated and discussed the fact that hearing protective devices (HPDs) reduce user sound exposures when properly worn. This means that all sounds may be attenuated, both unwanted sounds (noise) and useful sounds such as speech and warning signals. Thus wearing HPDs may affect speech discrimination, and the perception of warning signals. The magnitude and qualit...

background and purpose: many workers are exposed to workplace hazards. many occupational diseases are preventable by personal protective devices (ppds). though many workers do not use ppds or their protection by ppds is not sufficient. this study was designed to assess the quality of ppds usage among industrial workers. materials and methods: in a cross-sectional study, 648 workers from four ma...

Professional orchestral musicians risk permanent hearing loss while playing their instruments. Protecting the hearing of these musicians in the workplace is critical to their ongoing ability to play their instruments, but typical workplace hearing conservation measures can have very damaging effects on the product (music) and the musicians' abilities to hear one another sufficiently. To enable ...

OBJECTIVES After presbycusis, noise exposure is considered the second cause of sensorineural hearing loss. Due to exposure to high-intensity sounds, musicians may be at risk of noise-induced hearing loss (NIHL). Given the importance of good hearing in music career, this study aimed to investigate the frequency of hearing loss and use of protective measures among Iranian musicians. METHODS In ...
