Abstract: | This paper describes a short experiment undertaken to demonstrate how easily broad-band active control of sound can be used to tackle real industrial problems. Ten decibles of the low frequency sound entering an anechoic chamber through a lobby was blocked by using a single degree of freedom system. The experiment was set up, tested and demonstrated in a day. |
