Device for improving frequency discrimination in patients suffering from tinnitus has a microprocessor controlled signal generator that is used with patient answers in response to differentiation of different frequency signals

摘要

The microprocessor and its loaded algorithm select a tone pair with a randomized frequency difference from a frequency range matched to a particular patient. The microchip signal generator produced the tone in real time and transmits it into the headphones. The patient pushes yes-no buttons to indicate if he can differentiate between a tone pair. The microprocessor receives the feedback answer and selects the next tone pair frequency difference based on the answer. The invention also relates to a corresponding method.
