Whether a sound wave is reflected, refracted, or absorbed depends on the densities of the materials either side of the boundary. If the densities are very different then reflection is more likely.

Sound is the vibrations of an object. It is transmitted in the form of waves with alternate increase and decrease in pressure. A vibrating object compresses the surrounding air molecules making them ...

The type of wave, its properties such as wavelength, and the difference between the two media will determine what happens to most of the wave energy. Common examples of absorption of wave energy: ...

In addition to our other problems, we must also contend with transmission (with attenuation), reflection, refraction, diffraction, absorption, and scattering. In addition to our other problems, we ...
