Abstract
In one mode of operation, a signal representation of sound is provided to an audio filter that has transmission characteristics that are controlled by a microprocessor. The output of the audio filter is provided to similar left and right ear and a bone conduction processing circuits. Each of the processing circuits has an equalization filter that has transmission characteristics that are determined by the microprocessor. The outputs of the left and right ear and bone conduction processing circuits are connected to a left earphone, a right earphone and a bone transducer, respectively. The outputs of the processing circuits are in accordance with a program stored in a memory unit and are in accordance with plurality of procedures for assessment and training of a person's listening ability. In another mode of operation, a voltage to frequency converter generates a voltage having a frequency in accordance with signals provided by a microprocessor. The output of the converter is connected through an attack/decay filter to the input of the processing circuits.
