Sound

Why do you want to do this?

 

I ask because there is a recognised allied technique called audio signature analysis.

 

This works in one of two ways.

 

Structures and machines naturally produce vibratory signals that can be picked up with a microphone and analysed for fault conditions.

It is said that a good mechanic can tell what is wrong with your car by listening.

 

Additionally response to imposed signals can be tested in the same way.

Materials' properties for shocks aren't well known. Metals and ceramics are known for shocks at small speed that stay below the proof stress. Plastics and elastomers aren't accurately known. Inelastic flow isn't accurately known, and depends much on each material sample.

 

And then you have the shape and size of the objects. For real cases, it needs a software to evaluate the sound propagation is the parts and then in the air.
