Abstract
A sound attenuating system is provided which allows a relatively unobstructed airflow conduit to be associated with chambers that reflect various frequencies of sound back towards the source of the sound. The chambers are arranged in a coaxial association with the primary airflow conduit and are sized to reflect a certain range of frequencies of sound. Holes extend through the airflow conduit, in a radial direction, to place the airflow conduit in fluid communication with the chambers which surround portions of the conduit.
