Filters selectively amplify low,medium or high-pitched sounds, to select for low-pitched heart sounds, mid-range
murmurs or high-pitched lung sounds. One has multiple filters for greater control over sound than stethoscopes
that limit the choice to Bell or Diaphragm.
Pitch (i.e. frequency) is measured in Hertz (Hz) and displayed graphically on a low-to-high Hz Scale, which
shows relative frequency range - filters that amplify low-pitched sounds show LEDs towards the left, filters for
higher pitched sounds show LEDs toward the right.
The following filters are provided in your Thinklabs One. Factory default favorites are set to Filter 1 and Filter 3.
(Note that the filters on your One might be different from the list provided here.)
1. 30Hz - 500Hz. Produces strong low frequencies for heart sounds, especially S3. Bass may
0 Hz
be challenging for some third-party headphones and other external devices. An intense version
of a Bell mode.
2. 60Hz - 500Hz. Good for heart sounds, especially if Filter 1 bass is too intense for your tastes.
0 Hz
Similar to Bell mode.
3. 80Hz - 500Hz. Good for lung sounds, heart valve clicks, S2 splits. Removes lower heart
0 Hz
sound frequencies. Similar to Diaphragm mode.
4. 100Hz - 1000Hz. Good for lung sounds. Filters out lower frequencies and vibrations.
0 Hz
Provides more high frequencies for lung sounds than Filter 3, but this will also increase
ambient sound slightly.
5. 20Hz - 2000Hz +/-3dB. Wideband mode, very sensitive. Intended for capturing professional
0 Hz
research/academic recordings. Also great for listening if you can handle the sensivitity or you
tend to listen at lower volumes.
