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 threshold shift (TTS). The damage can become permanent (permanent threshold shift, PTS) if sufficient recovery time is not allowed before continued sound exposure. [1]
The tone decay test (also known as the threshold tone decay test or TTDT) is used in audiology to detect and measure auditory fatigue. It was developed by Raymond Carhart in 1957. In people with normal hearing, a tone whose intensity is only slightly above their absolute threshold of hearing can be heard continuously for 60 seconds.
TTS (Temporary Threshold Shift) is a temporary change of the hearing threshold the hearing loss that will be recovered after a few hours to couple of days. Also called auditory fatigue. TTS is also measured in decibels. In addition to hearing loss, other external symptoms of an acoustic trauma can be: Tinnitus [10] Otalgia [11] Hyperacusis [10]
Listener fatigue (also known as listening fatigue or ear fatigue) is a phenomenon that occurs after prolonged exposure to an auditory stimulus. Symptoms include tiredness, discomfort, pain, and loss of sensitivity. Listener fatigue is not a clinically recognized state, but is a term used by many professionals.
The absolute threshold of hearing (ATH), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.
From this relationship conclusions can be drawn about the processing methods of the human auditory system. Aspects of auditory event investigations can be: is there an auditory event? Is a certain sound noticeable? => Determination of perception thresholds like hearing threshold, auditory masking thresholds etc.
The auditory detection threshold for AM as a function of AM rate, referred to as the temporal modulation transfer function (TMTF), [49] is best for AM rates in the range from 4 – 150 Hz and worsens outside that range [49] [50] [51] The cutoff frequency of the TMTF gives an estimate of temporal acuity (temporal resolution) for the auditory ...
The lowest equal-loudness contour represents the quietest audible tone—the absolute threshold of hearing. The highest contour is the threshold of pain. Churcher and King carried out a second determination in 1937, but their results and Fletcher and Munson's showed considerable discrepancies over parts of the auditory diagram. [5]
