auditory fatigues การใช้

• There are two main types of auditory fatigue, short-term and long-term.
• The OHCs are the most fragile of the hair cells, hence their involvement in auditory fatigue and other hearing impairments.
• Usually, minor bending of the stereocilia ( inner ear ) is associated with temporary hearing loss and is involved in auditory fatigue.
• Also, the combined effects of these chemicals and the noise produce greater auditory fatigue than when an individual is exposed to one factor immediately followed by the next.
• However, when several sudden intense noises are presented at a pace higher than 2 3 seconds of interval, the acoustic reflex is able to play a role against auditory fatigue.
• There are several factors that may not be harmful to the auditory system by themselves, but when paired with an extended noise exposure duration have been shown to increase the risk of auditory fatigue.
• It is important to understand that noise exposure itself is the main influential factor in threshold shifts and auditory fatigue, but that individuals may be at greater risk when synergistic effects take place during interactions with the above factors.
