Abstract

The installation is for use in speech and related the rapies where the treatment is particularly aimed at the functioning of the inner ear, and converts audible frequencies into electrical signals which are amplified and filtered and then converted back into audible signals. Conditioning stages are arranged in cascade, each state comprises first and second circuits, each circuit including a separate amplifier and a filter having a variable frequency characteristic. The introduction of these units into the conditioning channels is controlled by a common switching circuit. Two such chains of conditioning circuits provide individual treatment of signals being fed to the two parallel (left and right) output earphones and loudspeakers.
