Noise-induced hearing loss in rats.
The effect of noise exposure on the auditory system is well known from animal studies. However, most of the studies concern short-term exposure conditions. The purpose of the present research was to find the dose-effect curve for hearing loss in rats following 5 days of noise exposure. Three groups of eight Wag/Rij rats were exposed to broad band noise

Occupational hearing loss: tonal audiometry X high frequencies audiometry
Introduction: Studies on the occupational exposure show that noise has been reaching a large part of the working population around the world, and NIHL (noise-induced hearing loss) is the second most frequent disease of the hearing system.

Noise-induced hearing loss and hearing aids requirement.
Subjective disturbances, due to hearing loss, are auditory disability and handicap which can be evaluated with a questionnaire. The present study refers to a population of industrial workers affected by noise-induced hearing loss. Aim of the study is to identify the minimal level of hearing loss over which the patient felt changes in his quality of ...

Effect of an initial noise induced hearing loss on subsequent noise induced hearing loss
Hearing Research, 2004The effect of previous noise induced hearing loss (NIHL) on subsequent NIHL was studied in rats. Three groups of animals were initially exposed to different durations of 113 dB SPL broad band noise (21 days, 3 days or 0 days--unexposed). Their permanent threshold shifts (PTS) from this exposure (PTS1) were evaluated using auditory nerve-brainstem ...

Tinnitus in noise-induced hearing loss
British Journal of Audiology, 1985Tinnitus was analysed in 94 patients with noise-induced hearing loss. Tinnitus of a pure tone character was most common followed by narrow-band noises, and a combination of these. A broad-band noise type of tinnitus was the least common finding. Tinnitus was most common at high frequencies.

Noise-induced hearing loss is a major hazard in many workplaces and in society. The National Institute for Occupational Safety and Health estimates that more than 30 million workers (almost 1 in 10) are exposed to unsafe noise levels on the job. Helicopter emergency medical services crews work in an environment in which exposure to aviation noise makes

Recruitment in Noise-Induced Hearing Loss
Acta Oto-Laryngologica, 1966A group of subjects with sensory-neural noise-induced hearing loss was tested with a fixed-frequency Bekesy type audiometer. Responses were studied for signs of abnormal auditory adaptation and increased differential sensitivity. Adaptation was defined as a poorer threshold response to a continuous tone than to an interrupted tone.

Presbycusis and Noise-Induced Hearing Loss*
Ear and Hearing, 1990In a longitudinal and an age cohort comparing study the influence of aging and occupational noise exposure on hearing sensitivity was studied. The participants of the longitudinal study were studied at 70, 75, and 79 years of age. Seventy year old men exposed to occupational noise had 10 to 15 dB poorer hearing in the high frequency range than ...
