ABSTRACT:
A tinnitus masking device and method for producing a masking signal with a selected center frequency, selected bandwidth, and selected volume is provided. A random noise generator and a clock circuit are employed in conjunction with a switched capacitance filter bank to produce a masking signal with the selected center frequency and selected bandwidth. The masking signal is then received by a volume control unit and then amplified for delivery to the tinnitus sufferer's ear or ears by speakers or headphones. Additionally, the tinnitus masking device may include a timer and fade out unit.
