Is there any way to simulate sound transmission properties of the human body with solid materials?

While there are several sound sources inside the human body (heartbeat, air flow, bubbles moving inside the intestines) only a very small amount is transferred to the sourrounding air. It can however be tapped on by a stethoscope in a quite efficient fashion.

Is this process comparable to sound in and over water, where sounds sources underwater can be heard well underwater but almost nothing leaves the water?

Is it possible to create a solid body that would transmit almost no sound to the air, but can be tapped on with a stethoscope?

  • $\begingroup$ If I tap ultrasonic via a stethoscope, it keeps ultrasonic and I hear nothing I guess... so no good simulation of human body sounds. $\endgroup$ – dronus Jul 15 '16 at 20:13

Use a ballistics dummy.

Ballistics dummies are designed and constructed to approximate the mechanical properties of the human body. They consist primarily of a molded ballistics gel designed for the same purpose. They are used most commonly for ballistics testing done by forensics and crime labs.
