Question

What is the “temporary threshold shift”?
A. Hearing loss due to excessive noise
B. Intolerable noise
C. Tolerable noise
D. Inaudible noise

Answer 1

A temporary shift in the auditory threshold is called a temporary threshold shift. A high level of noise may occur suddenly after exposure to a situation in which most people experience reduced hearing. In the temporary hearing loss that the result is a temporary threshold shift.

Complete step by step answer:
Temporary threshold shift:
A temporary threshold shift (TTS) means a temporary hearing loss that occurs immediately after exposure to a high level of noise. There is a gradual recovery when the affected person spends time in a quiet place. Most people experience a rise in the auditory threshold which normally disappears in 24 hours, but may last as long as a week during short noise exposure.
Causes of temporary threshold shift:
A temporary hearing loss is normally caused due to a temporary threshold shift by exposure to intense and/or loud sounds or noise levels for a shorter or longer. This could be an explosion or a concert.
Treatment of temporary threshold shift:
A temporary threshold shift and it is recommended to you spend some time in a quiet place and not expose yourself to loud sounds.
How long does TTS:
A temporary threshold shift has various recovery times. TTS may take only a few hours for the symptoms but it can also last for days. If your hearing loss does not recover within a few days, you should seek medical advice.
Permanent TTS:
A permanent threshold shift is totally opposite of the temporary threshold shift. The ability to hear is reduced permanently due to a permanent threshold shift, which causes a permanent hearing loss.
Hence, the temporary threshold shift is hearing loss due to excessive noise.

Note: Temporary hearing loss can be considered a temporary audiometric characteristic.
Hearing impairment resulting from high noise exposure is included in auditory effects.
The main concern related to occupational noise exposure is noise-induced permanent hearing loss.
