A photo taken from the inside of an anechoic chamber. The effect of rebounding sound waves is kept to a minimum in such an anechoic chamber thanks to the large surface area that absorbs most of the noise.

Hermann Ludwig Ferdinand von Helmholtz (August 31, 1821 - September 8, 1894) was a German physician and physicist who made significant contributions to several widely varied areas of modern science. In physiology and physiological...
