The 3100 has a built-in
microphone, filtering circuits and low-noise amplifiers that
generate a superior acoustical response. The filter
circuitry provides three different frequency response modes:
bell (20-200 Hz), diaphragm (100-500 Hz) and extended range
(100-1000 Hz), which is where heart and lung sounds
occur. The amplifier lets the user amplify sounds up to
four times louder (15-20 dB) than the best conventional
stethoscope.
