The SS30L was developed to teach students the standard procedure for listening to heart sounds and Korotkoff sounds with a normal stethoscope and at the same time record sound data. A microphone in the stethoscope simultaneously records the sound the student is hearing, and the BSL software will display the soundwave during and after recording.
No calibration required, just select a Stethoscope Preset (Heart or Korotkoff Sounds).

The SS30L can be used with the SS19L Blood Pressure Cuff to record Korotkoff sounds for easy determination of systolic and diastolic blood pressure. With this combination, it is easy to obtain very accurate and repeatable results—usually within 10% of those determined by direct measurement.
If ECG is also recorded, the timing of the heart sounds with the ECG can be correlated.
Note: For research applications, the SS17L Physiological Sounds Microphone may be a more versatile option.

Recent Studies using BIOPACs MP-Series (MP160, MP150) data recorders, ECG Amplifiers, and BioNomadix Wireless recorders: Singing style to infants Mothers around the world sing to infants, presumably to regulate their mood and arousal. Lullabies and playsongs differ stylistically and have distinctive goals. Mothers sing lullabies to soothe and calm infants, and playsongs to engage and […]
