attenuator

[ə′ten·yə‚wād·ər]
(electronics)
An adjustable or fixed transducer for reducing the amplitude of a wave without introducing appreciable distortion.

sound attenuator

In ductwork, a device (usually prefabricated) especially designed to provide much greater sound attenuation than would be provided by an equal length of ductwork; the pressure drop through the device is greater than for an equal length of ductwork.
