Established in 1959, the Societys remit is to help find solutions to noise pollution problems which it does through working with diverse stakeholders to find innovative, practical and holistic solutions. The Societys founder, John Connell OBE, lobbied the Noise Abatement Act through parliament in 1960 making noise a statutory nuisance in the UK for the first time);

Why are you writing a book about the history of NOISE?, people asked. And what is noise anyway?, they didnt add. But perhaps they should have. Noise is not quite as simple as it sounds, as we shall soon discover. But first: why a noise book? Because noise is more relevant todayand will be more relevant tomorrowthan ever before, thanks in part to the growth of its sources and in part to the more concerted efforts of governments to quash it. Not that quashing is always relevant: noise is by no means always bad.
Probably what most people mean when they use the word is unwanted soundand indeed this definition of noise has been in common use since the Middle Ages, or perhaps even earlier. But unwanted sound is hardly a definition likely to satisfy a philosopher or a lawyer: is
