We want to help our customers achieve the highest quality auscultation when using our products, please follow the steps below to better ensure superior audio quality.
When using the Littmann CORE:
- If possible, perform auscultation in a quiet environment. While the Littmann CORE has active noise cancellation, there is a chance that some environmental noise will still be audible during auscultation.
- Use the bell to best listen to low frequency sounds like heart sounds. Use the diaphragm to best listen to high frequency sounds like lung sounds.
- Hold the diaphragm firmly against the surface you will be auscultating from. Pressing too tightly against the surface can muffle sounds.
