Abstract:
A new stereophonic stethoscope is presented. It is characterized by a single chest piece construction housing paired open-bell type sound accumulating chambers and paired diaphragm type sound accumulating chambers. A pair of separate ear tubes connected to each of the paired sound chambers establish two cross talk-free channels for collecting and delivering auscultatory sounds. Selective use of the open-bell and diaphragm sound chambers is assured with this new stethoscope. Advantages of stereophonic auscultation are discussed.
