In results, the reflected sound is scattered at many angles. Thus, the reflection angle will vary according to which surface the incident sound hits. In this case, the incident sound hits many different surfaces each of them has a distinct normal line. When a sound wave strikes a rough or irregular surface, it actually follows the physics of reflection as we have discussed above-the sound wave will bounce back at the same angle as its incident wave. If you observe how the sound hits a rough surface, you may discover that there are many reflected sounds and each of them goes in a different direction.

However, in the real world, we may find that all reflections do not always seem to behave that way. For reflection in a flat surface, the reflection angle equals to the incidence angle. The same applies to the reflection angle. The angle between the direction of the incident sound wave and the normal line is then what we define as the incidence angle. Let’s see the illustration below to help you imagine how the sound bounces after it hits a surface.ĭraw a line perpendicular to the surface that starts from the point on which the sound wave is incident. If you ever learn physics of sound in middle school, you may still remember that the reflected sound will have the same angle as the incident sound. When a sound wave strikes a surface, we can confidently say that some of the energy will bounce back in a different direction. When a sound wave propagates in a closed space and strikes one of the surfaces, it may undergo one or more of the following behaviors: (1) reflection, (2) absorption, (3) diffusion, (4) diffraction, and (5) resonance.

It depends on how you control those behaviors so that the sound waves can act the way you want. Some behaviors can improve or degrade sound quality inside a room. To create high sound quality for music venues or speech listening rooms, we need to learn the science behind sound behaviors.
