When sound is redirected in multiple directions after hitting a rough surface, this is called:

• A. Scattering
• B. Refraction
• C. Specular
• D. Voxel

Answer: (A)

Scattering is what happens when sound hits a rough surface and is reflected in many directions. The roughness means countless microfacets are oriented differently, so each facet sends energy in its own direction, and the overall sound energy spreads out rather than reflecting off in a single path. If the surface were smooth, you’d get specular reflection, a single mirror-like direction. Refraction would involve the wave changing speed and bending as it moves into a different medium, not the multi-directional spread caused by surface roughness. A voxel is just a 3D pixel used in imaging and isn’t related to how sound redirects.
