Using Stethoscope Filters

ClearSteth offers various audio filters that isolate specific audio frequency ranges to allow users to better hear the organs systems of interest.

Clinical evidence indicates that heart sounds begin below the audible threshold of 20 Hz and do not exceed 1000Hz - with most being heard between the 20-500Hz range. High frequency heart sounds, such as murmurs of aortic insufficiency and mistrial insufficiency, are better heard with the use of a diaphragm that filters out the low frequency components of other heart sounds. Lung sounds are classified into the following groups: Low (under 100 Hz), middle (200-600Hz), and high frequency (600-1200Hz). These categories include the majority of clinically relevant respiratory sounds (crackles, wheezes, rubs, etc), even the highest pitched wheezes rarely exceed 2000 Hz.

1. Littman Stethoscope Filters - users on the receiving end of a Littman stethoscope call will be presented with 3 options for filtering the stethoscope audio.
