Exceptional Acoustic Effectiveness
Most significant heart sounds occur in a frequency range (200 Hz to 500 Hz) well under the opti-
mal human auditory threshold of 1000 Hz.
The diaphragm of the Elite has been quantitatively verified to effectively transmit and amplify this most important range of heart sounds. The bell chest piece of the Elite is used for detection of lower frequency sounds from 20 Hz to 100 Hz
