Tips for Best Sound Quality
• Apply Probe with light, steady contact, not excessive pressure.
• The ds32a works best with direct skin contact. Using through clothing is possible, but less optimal.
• Experiment to find a preferred Volume level that optimizes recording and listening clarity. When you
are recording, optimize for recording quality. Generally, higher volume settings produce better
recording quality.
• The EmD Diaphragm responds to adjustments in applied pressure, affecting both sensitivity
(loudness) and frequency characteristics. This is a very powerful, tactile way to control sound. In most
cases, simply apply a light but consistent pressure. Do not push too hard. Gradually increasing
pressure will increase sensitivity and loudness. At significant pressure, low frequencies are cut, making
breath sounds more audible than heart sounds.
• It is sometimes helpful to hold the Probe so that the fingers also
touch the patient chest wall (such as the left edge of the thumb and
the fingertips in figure to the right.) The Probe and chest wall then
move in unison, for a consistent, light diaphragm pressure.
• The ds32a Manual contain USEFUL TIPS for obtaining best results.
