Filter Settings

Thinklabs One allows you to listen with multiple frequency filters simply by pressing the "filter" button (top left with audio jack facing right). You can even set two filters that you use most often as "favorites," making them super-fast and easy to select. This is similar to using the Bell and Diaphragm modes on a conventional stethoscope.  The filter choices on the One range from very low frequency sounds, like heart sounds (low-pitched sounds such as S3), to higher frequencies such as lung sounds.

The Hz scale on the stethoscope display indicates the filter range selected.  LEDs on the left side of the scale indicate lower frequencies will be reproduced; LEDs on the right indicate higher frequencies will be reproduced. The more LEDs that are on, the wider the range of frequencies;  the narrower the indication, the narrower the range of frequencies. 

In addition to filter settings, you can change the frequency response by applying more or less pressure on the diaphragm. As you push on the diaphragm, the "gap" in the sensor changes, which modifies the sensor's response to lower frequencies. 

To find out more about the frequency filter settings in One, please see the insert included with the stethoscope ("The Audio Filters in Your One") and check out the
Filter Selection section of the manual.
