An electronic device is provided for receiving sounds from a body. A microphone array receives the sounds. An analysis system optionally provides for directional control, such as by providing virtual focusing and beam steering. Body sounds are preferably de-convolved. In certain embodiments, a plurality of buffer structures are located in cavities in a patch adjacent the microphones to provide for improved sound pick-up. In certain embodiments, at least two of microphones are spaced at least 2 centimeters apart. Preferably, wireless transmission circuitry sends information relating to the sounds in the body, and optionally receives information, such as control or status information. Target selection and acquisition systems provide for the effective capture of multiple sounds from the body, even when the device is adhered to the body by the user, that is, not a skilled physician. |
