Sound engineers use spongy materials on walls to absorb sound waves.
Sound engineers use spongy materials on walls to absorb sound waves. These materials, known as acoustic panels or absorbers, are designed to control the reflections of sound in a room. When sound waves hit a hard and flat wall surface, they can bounce off and create unwanted echoes or reverberations. This can result in poor sound quality, especially in spaces like recording studios, theaters, or auditoriums.
To solve this problem, sound engineers strategically place spongy materials, such as foam or fabric-covered panels, on walls to absorb the sound waves instead of reflecting them. These materials have a porous structure that allows them to convert sound energy into heat, effectively reducing the intensity and prolongation of reflections in the room.
By absorbing sound waves, these spongy materials help to create a more balanced and controlled acoustic environment. This is crucial for accurate sound reproduction, better speech intelligibility, and reducing unwanted background noise.
what happens when a wave is absorbed by a material
A. the wave supports the formation of an echo
B. the wave passes through the material
C. the wave bounces off the surface of the material
D. the wave transfers its energy to the material
