Tinnitus in occupational hearing loss: nosological aspects
The Journal of Otolaryngology
|February 1, 1987
Summary
Tinnitus, often experienced by workers with hearing loss, affects over half of those claiming compensation. This high-pitched ringing in the ears was a major issue for 19% of these individuals.
Area of Science:
- Occupational health
- Audiology
- Otolaryngology
Background:
- Tinnitus is a common symptom associated with occupational hearing loss.
- Understanding tinnitus characteristics in this population is crucial for effective management and compensation.
Purpose of the Study:
- To analyze the incidence and characteristics of tinnitus in a large cohort of workers with occupational hearing impairment.
- To explore potential relationships between tinnitus and factors like noise exposure and hearing loss severity.
Main Methods:
- Retrospective analysis of detailed case histories from 2,442 workers' compensation claimants for hearing impairment.
- Data collection focused on the presence, severity, and nature of tinnitus.
Main Results:
- Tinnitus was reported by 58% of claimants, with 19% rating it as a major problem.
- The condition was typically bilateral, tonal, high-pitched, and showed no ear-specific differences.
- No clear link was found between tinnitus incidence and hearing loss severity, but a higher incidence was noted in workers exposed to impulse noise.
Conclusions:
- Tinnitus is highly prevalent among workers with occupational hearing loss.
- Impulse noise exposure may be a significant factor in tinnitus development.
- Further research into the specific mechanisms and management of tinnitus in this demographic is warranted.

01:31Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
03:18Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
00:53Sound Intensity Level
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...
