What is the difference between diffusion, diffraction, reflection and refraction?
Diffraction -The act of sound waves traveling around barriers especially pronounced when the sound wavelength size is comparable to or greater than the dimensions of the barriers. Diffuse Field -Area, within a room, where the sound pressure levels do not vary significantly with location. -Caused by reverberation. Diffusion -The scattering or random reflection of a sound wave from a surface. The directions of reflected sound are changed so that listeners may have sensation of sound coming from all directions at equal levels. Reflection -The amount of sound wave energy (sound) that is reflected off a smooth, hard surface. Some sound reflection can enhance the quality of the signal of speech and music. Refraction -The act of sound waves bending or changing propagation direction as they travel from one medium or medium condition (such as temperature, density, humidity, or wind current) into another.
