Stethoscope having pseudostereophonic binaural enhancement
First Claim
Patent Images
1. A stethoscope for use in listening to body sounds comprising:
- a monophonic microphone for sensing said body sounds and converting said body sounds into a corresponding monophonic signal;
a right earphone and a left earphone enabling binaural hearing by a user of said stethoscope;
transversal filter means for converting said corresponding monophonic signal into a corresponding different output signal;
means for transmitting said corresponding different output signal to only one of said earphones; and
means for transmitting said corresponding monophonic signal to the other one of said earphones;
whereby sounds heard in said right and left earphones are different and create a pseudostereophonic effect during binaural hearing by said user.

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.

5. A stethoscope for listening to body sounds comprising:
-
a monophonic microphone for sensing said body sounds and converting them into a corresponding monphonic signal; a right earphone and a left earphone enabling binaural hearing by a user of said stethoscope; transversal filter means for converting said corresponding monophonic signal into two different corresponding output signals; and means for individually connecting said two different corresponding output signals to respective ones of said right and left earphones to produce different sounds for said right and left earphones; whereby the different sounds heard in said right and left earphones create a pseudostereophonic effect during binaural hearing by said user. - View Dependent Claims (6, 7, 8, 9)
