Abstract: It is presented a sensor comprising a sensor plate (14), a base piece (15) and a first sensor membrane (7a) and a second sensor membrane (7b), each having a side of positive electrical polarity and a side of negative electrical polarity. Each one of the first sensor membrane and the second sensor membrane is mounted between the sensor plate and the base piece while allowing movement of the sensor plate in relation to the mounting piece. The first sensor membrane and the second sensor membrane are mounted such that their respective sides of positive electrical polarity face each other or face away from each other. A corresponding electronic stethoscope is also presented.

Abstract: An electronic sound monitor for use as a stethoscope, a signal treatment and a method for treating the signals using the monitor. The sound monitor comprises at least one transducer for transforming vibrations to electrical signals (217; 701, 702) , filtering means (705) , A/D- and D/A-converter means (707,715) amplification means (703,704,706,716) , processing means (708), a sound chamber (215) in which at least one transducer for transforming electrical signals to sound (214) is arranged, and a sound channel (212) opening into said sound chamber, said sound channel adapted to forward the sound from the sound chamber (214) through an opening (218) connecting the sound channel with the ambient air.
