Threshold shift can also cause threshold pressure to vary.

Residual inhibition overlaps tinnitus spectra and the region of auditory threshold shift.

Threshold Shift.

Temporary threshold shifts related to auditory fatigue are related to the amplitude of a stimulus-driven traveling wave.

This is called noise-induced permanent threshold shift (NIPTS)

This results in a temporary shift of the auditory threshold known as a temporary threshold shift (TTS).

If a significant change in hearing capabilities occurs (called a standard threshold shift) greater steps must be taken to ensure the employee is protected from high levels of noise exposure.

In humans, individuals with the p.W301X missense mutation (DFNB95) exhibit bilateral sensorineural hearing loss with threshold shifts of 70-80 dB hearing levels as early as 11 months of age.

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.
