Abstract

This paper presents a new type of silencer based on the technique of no-source active noise control(NSANC) with no secondary loudspeakers.It measures and analyses the real time noise signals.Then controlling system drives the executing structure in responses of the test results by the rules of fuzzy control.So the silencer can work at the best noise attenuation state all the while.
