Abstract
A stethoscope having a monophonic electrical sensor which feeds electrical signals corresponding to heart sounds to a transversal filter to produce pseudostereophonic signals at split outputs which may be used to power dual earphones for binaural listening. The electronic processing of the heart sounds in the transversal filter enables the listener to differentiate the different sounds of the heart.
