Explanatory Model for Sound Amplification in a Stethoscope
Eshach, H.; Volfson, A.
Physics Education, v50 n1 p75-80 Jan 2015
In the present paper we suggest an original physical explanatory model that explains the mechanism of the sound amplification process in a stethoscope. We discuss the amplification of a single pulse, a continuous wave of certain frequency, and finally we address the resonant frequencies. It is our belief that this model may provide students with opportunities to not only better understand the amplification mechanism of a stethoscope, but also to strengthen their understanding of sound, pressure, waves, resonance modes, etc.
