In thread384-25674 (same title as above, but dated 22 Jun 02, otaio (Electrical) posted the question:
"I would like to understand the physics of why sound pressure doubles at a surface and how the thickness of the this boundary can be calculated.".
Subsequent to this, MikeyP responded
"The distance where pressure doubling occurs depends on 3 main parameters:
- The angle of incidence of the wave,
- the absorpative characteristics of the surface (both attenuation and phase shift) and
- the wave length.
The first link above shows the simplest case of a normally incident wave on a perfectly reflecting surface."
What I would like to know is this; is there a more detailed technical explanation for this? Is there a set of equations or a formal theory which ties in the 3 factors mentioned above? I am performing a research project into pressure doubling and all help is much appreciated!
