ABSTRACT:
An improved personal noise attenuation system which attenuates both tonal and broadband sound and which includes a spatially adjustable acousto-electric sensor and attenuation means including both feedback and feed forward components so as to provide a heteronomous attenuation and more complete active noise attenuation and the adjustable acousto-electric sensor is moved to exploit the changing physical characteristics of spatial silent zones in different noise fields.
