An audiogram displaying listening to lack of lower than 25 dB in any respect frequencies as much as 6000 Hz could be considered showing hearing inside the regular range. If bone conduction values are all lower than 25 dB, but some or all air conduction values are 25 dB or extra, a conductive listening to loss could also be current.
Nature – exposure to extreme sounds (acoustic trauma) produces a temporary shift in the stimulus threshold of the outer hair cells inside the inside ear, so permitting them to recover. Sufficiently intense and repeated exposure leads to a everlasting threshold shift. Occupational listening to loss is the principal wrongdoer but any noise, including military, social and firework noises, can all be implicated.
