[Noise-induced hearing loss and tinnitus].
The presence of subjective tinnitus is an important aspect in the evaluation of hearing loss induced by noise. Tinnitus due to this condition is characterised by a frequency of 3,000 Hz or above and is closely related to the frequency range of maximal hearing loss. Tinnitus below 1,000 Hz is not induced by noise, and indicates the presence of a different cause for the hearing loss. This type of tinnitus should not be regarded as an occupational disease: it requires extensive investigation.
Abstract Background and aims: Occupational noise is a major cause of hearing loss and tinnitus. In the present study, acoustic characteristics of tinnitus were evaluated and their relation with hearing loss and nervousness was studied. Methods: Our study was performed on 56 male workers aged between 40 to 56 years including 28 workers with accompanied hearing loss and tinnitus and a long ...متن کامل
Effects of Exposure to Impact Noise on the Hearing of Armed Forces and Evaluation of the Methods to Control and Decrease its Consequences: A Review Study
Background and Aim: Exposure to impact noise (short-term, high intensity) higher than permitted levels results in injury to the auditory system. Armed forces are one of the occupational groups exposed to these types of noises resulting from gunshots. In this study, relevant articles and research on the adverse effects of impact noise, hearing loss, and tinnitus in armed forces and effective con...متن کامل
Objective(s): Noise-induced hearing loss (NIHL) is the major cause of acquired hearing loss. Celecoxib, a cyclooxygenase-2 (COX-2) inhibitor, is a non- steroidal anti- inflammatory drug (NSAID) with known antioxidant and antineoplastic activity. Therefore, we monitored the extent of temporary noise- induced threshold shifts (TTS) and cochlear damage caused by high level 4- kHz noise exposure t...متن کامل
The More the Worse: the Grade of Noise-Induced Hearing Loss Associates with the Severity of Tinnitus
Tinnitus disturbs lives and negatively affects the quality of life of about 2% of the adult world population. Research has shown that the main cause of tinnitus is hearing loss. To analyze a possible association of the degree of hearing loss with the severity of tinnitus, we have performed a retrospective study using admission data on 531 patients suffering from chronic tinnitus. We have found ...متن کامل
INTRODUCTION Tinnitus is one of the symptoms that affects individuals suffering from noise induced hearing loss. This condition can be disabling, leading the affected individual to turn away from work. OBJECTIVE This literature review aims to analyze the possible association between gender and tinnitus pitch and loudness, the degree of hearing loss and the frequencies affected in subjects wit...متن کامل
