Intrinsic absorption coefficient
WebApr 1, 2024 · However, it is difficult to achieve high sound absorption coefficient only by the intrinsic damping properties. To further improve the sound absorption properties, other mechanisms need to be introduced. 4.4.2. Scattering and reflection. Sound scattering is the specular reflection of waves from small segments of a rough surface.
