As with any type of hearing-related disorder, the related physiology is within the ear and central auditory system. With regards to listening<unk> , the relevant mechanical and biochemical mechanisms primarily deal with inner ear and cochlea. Associated anatomy The stereocilia (hair cells) of the inner ear can become subjected to bending from loud noises. Because they are not regeneratable in humans, any major damage or loss of these hair cells leads to permanent hearing impairment and other hearing-related diseases. Outer hair cells serve as acoustic amplifiers for stimulation of the inner hair cells. Outer hair cells respond primarily to low-intensity sounds. Human Ear Anatomy. Relevant mechanisms Vibration Excessive vibrations that occur in the inner ear can result in structural damage that will affect hearing. These vibrations result in an increase in the metabolic demands of the auditory system. During exposure to sound, metabolic energy is needed to maintain the relevant electrochemical gradients used in the transduction of sounds. The extra demands on the metabolic activity of the system can result in damage that can propagate throughout the ear. Temporary threshold shifts When exposed to noise, the human ear's sensitivity to sound is decreased, corresponding to an increase in the threshold of hearing. This shift is usually temporary but may become permanent. A natural physiological reaction to these threshold shifts is vasoconstriction, which will reduce the amount of blood reaching the hair cells of the organ of Corti in the cochlea. With the resultant oxygen tension and diminished blood supply reaching the outer hair cells, their response to sound levels is lessened when exposed to loud sounds, rendering them less effective and putting more stress on the inner hair cells. This can lead to<unk>  and temporary hearing loss if the outer hair cells do not get the opportunity to recover through periods of silence. If these cells do not get this chance to recover, they are vulnerable to death. Temporary threshold shifts can result in different types of<unk> . Short-term<unk>  Recovery from temporary threshold shifts take a matter of minutes and shifts are essentially independent of the length of exposure to the sounds. Also, shifts are maximal during and at frequencies of exposure. Long-term<unk>  Long-term<unk>  is defined as full recovery from temporary threshold shifts taking at least several minutes to occur. Recovery can take up to several days. Threshold shifts that result in long-term<unk>  are dependent on level of sound and length of exposure.
