A hand-held device, or "pod" (102) incorporates an acoustic sensing element (206) for capturing sound waves, and a position-indicating display (104) for displaying telemetry data. The acoustic sensing element (206) extends partially from an aperture on the bottom of the pod (102). The sensing element is spring-mounted (204) in order to apply moderate and controlled pressure against the chest or back of a patient. The pod (102) houses a printed-circuit board (202), supported by studs (208). Electronics mounted on the printed-circuit board includes preamplifier circuitry, cursor control circuitry, telemetry circuitry, and/or other circuitry for processing signals to/from the sensor (206).
