ABSTRACT:
Electronic hearing apparatus comprising a plurality of stages in cascade each constituted by a pair of first and second operating circuits each containing an amplifier and a filter having selected response and a common control circuit for opening the first and second operating circuits to selectively and quantitatively determine the passage of signals through the two operating circuits. The first operating circuits constitute together a first channel having outputs connected in parallel to individual transducers of one or a plurality of output devices associated on one side, right or left, of the subject and all of the second circuits constitute together a second channel having their outputs connected in parallel to individual transducers of one or a plurality of output devices associated with the other side, left or right, of the subject, the various transducers transforming the received electrical signals to vibratory or sound signals.
