An electronic stethoscope consisting of a transducer, an amplifier and a headphone will be better adapted to the habits of use of doctors when it is supplied with filters which mimic the transfer function of acoustic stethoscopes. Thus, the signals heard will correspond to those learnt, and thereby the advantages of greater amplification and elimination of noise sources may be fully utilized. Hence there is a possibility for extended digital signal processing which may furthermore compensate for the hearing loss of each individual doctor. |
