Phonendoscope

 

a medical instrument used for listening to cardiac, respiratory, and other sounds originating within the body (that is, for the same purposes as the stethoscope). A phonendoscope is always binaural, consisting of two tubes whose ends are inserted into the ears. It differs from the flexible stethoscope in that the auscultatory chamber is covered with a rigid membrane for intensifying the sounds.
