Echoes on Echoes©

Echoes on Echoes© is considered a good test for the non-verbal or difficult to test. It consists of various frequencies, steady and changing. They were frequency-modulated, interrupted and reverberated between tracks at various rates and degrees. Often the signal appears to move from one transducer to the other (when presented dichotically, or through stereo speakers).

The purpose is to provide novel stimuli for attracting attention. The recording has been employed successfully to estimate hearing levels of severely mentally retarded individuals who had resisted more conventional efforts to ascertain hearing function. It is most effective when presented through a two-channel speaker system.
