Auditory fatigue
temporary loss of hearing after exposure to sound
Auditory fatigue is defined as a temporary loss of hearing after exposure to sound. This results in a temporary shift of the auditory threshold known as a temporary hearing threshold shift (TTS). The damage can become permanent (permanent hearing threshold shift, PTS) if sufficient recovery time is not allowed before continued sound exposure. When the hearing loss is rooted from a traumatic occurrence, it may be classified as noise-induced hearing loss (NIHL).
There are two main types of auditory fatigue, short-term and long-term. These are distinguished from each other by several characteristics listed individually below.
Short-term fatigue
Full recovery from TTS can be achieved in approximately two minutes.
The TTS is relatively independent of exposure duration.
TTS is maximal at the exposure frequency of the sound.
Long-term fatigue
Recovery requires a minimum of several minutes but can take up to several days.
The public source identifies “Auditory fatigue” as temporary loss of hearing after exposure to sound. This brief keeps that definition visible, then builds a research path around Auditory, fatigue and temporary.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Auditory fatigue”, the useful work is to connect “temporary loss of hearing after exposure to sound” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 23, 2026. The linked authority identifier is Q4820025. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
