How sound waves are made
Sound engineer Martin Desai of the School of Sound Recording in Manchester, using the aid of a slinky, to explain to Andy Williams and Jimi Goodwin of the band Doves how sound waves are made. Sound is explained as a series of compressions and rarefractions that travel through the air. Sound waves travel through the air and can be blocked. A basic explanation of wavelength is also included. How are high and low frequency sound waves affected when they travel through walls? He explains how low frequency sounds can travel much further through walls than high frequency waves leading to a dull, thudding noise travelling into the room.
