Microphone characteristics for capturing lung sounds?

26 January 2014 1 5K Report

Lung sounds are a diagnostic signal for many diseases. From this point I want to record lung sound with more accuracy and less noise. The mic is the first important element to achieve such request. What are the characteristics of such a mic?

piezoelectric microphones work well for recording sound from the heart (PCG) and from the muscles ( PMG )and, surely, also for lungs.
