Sound wave diffusion – the phenomenon of sound wave (acoustic) diffusion. Diffusion of acoustic waves can occur in several situations. This phenomenon occurs when a wave encounters an obstacle that is comparable to or slightly smaller than the wavelength itself. It also occurs when the obstacle, such as a wall or diffuser, has an irregular structure with protrusions or a sculpted surface. In this case, the acoustic wave reflects at various angles. Sound wave diffusion can also occur when the barrier is made of different materials, each with different properties regarding wave reflection.
Proper acoustic arrangement of rooms increases the scale of sound diffusion, thereby minimizing acoustic defects. This is essential if musical performances or sound recordings take place in a given location. Dedicated acoustic devices that can be mounted directly on walls or ceilings can help in sound diffusion.
