Abstract:
PI-PB functions were defined and analyzed for 66 aged listeners (108 ears). Abnormal rollover (greater than 0.40) was identified in four subjects (four ears). The current study showed the frequency and magnitude of the rollover phenomenon to be greater in an aged population when compared to the general clinical population. The diagnostic and rehabilitative applications of the PI-PB function and the rollover phenomenon are discussed.
