Download book Elements of Acoustics, Light, and Heat. Porous absorbers, as the name suggests, consist of porous materials. Their sound-absorbing effect comes from the fact that the sound waves can penetrate the surface of the material and flow into the cellular or fibrous structure, where they are dampened and converted into heat (the amount of heat is minimal less than one millionth of a watt).

Dark, subterranean spaces, such as water tanks or tunnels, can heighten disorientation and, in doing so, intensify a sonic experience. A combination of light and sound reflection, both physical and digital, enhances visitors senses in the installations of German artist Robert Henke.
In everyday life, the thermal effects of sound are too small to be easily noticed; 4 Basic components of a thermoacoustic system; 5 Acoustic driver; 6 Stack; 7 Heat sealing challenges particularly if the mixture has light gases like helium.

In the process the character of the light may be changed. Some of the so called "white light" from the sun bounces off grass to become "green" light. Somehow light must also carry information about the location and shape of the objects that we see. We normally assume that a thing is located in the direction where the light comes from. So it
