Sound reflecting mirrors

Paul 'scruffy' Martin finds out about Major William Sansome Tucker, DSc, OBE (1877 - 1955) who was a British pioneer in acoustical research. He was born in Kidderminster, the son of William Tucker, an artist painter, and his wife Anna. Tucker became Director of Acoustical Research, Air Defense Experimental Establishment, Biggin Hill. His work eventually led to vast parabolic 'sound mirrors' being constructed from concrete. Some of these sound mirrors still survive along England's south coast, such as those to be found at Denge, near Dungeness, to the west side of a lake slightly north of Lydd-on-Sea. Tucker's work was superseded by the development of RADAR, which made sound-ranging using the great concrete mirrors obsolete.
