Abstract

An attenuation system includes a device having a first housing from which audible noise generated during operation of the device emanates outwardly from the first housing. A second housing substantially surrounds the first housing. A conduit extends from the first housing and exterior of the second housing, the conduit substantially vibrationally isolated from the second housing. A vacuum is formed between the first housing and the second housing.
