Example 2: A pure tone of 1000 Hz --This a represents a periodic oscillation with energy concentrated at a single frequency at the center of the speech range. Although complete recovery from a given episode can occur, repeated episodes of such shifts occurring after noise exposures give way to permanent threshold shifts because hair cells in the cochlea are progressively lost.
