What's the difference between Phonendoscope and Stethoscope?

Answer 1

A phonendoscope is a stethoscope that intensifies auscultatory sounds.

Answer 2

I doubt mr top contributor even knows what auscultatory sounds are.
A phonendoscope allows the doctor to hear a more isolated and specific sound regarding your heart and abdominal area. Doctors will use a phonendoscope to listen for a heart murmur or even sounds during pregnancy. A stethoscope is just the common instrument doctors typically use to listen to breathing patterns like asthma or mucus in your lungs.
