  • Sound engineer Martin Desai of the School of Sound Recording in Manchester, explains to Andy Williams and Jimi Goodwin of the band Doves how sound waves that musical instruments make can interfere with each other. In the music industry this is called phase cancellation but is otherwise known as constructive and destructive interference of waves in physics. If two waves arrive at the same time they can join together to either cancel each other out (destructive interference) or join together (constructive interference) to produce a larger waveform.
