Abstract
An active noise attenuation system (10) comprises a speaker (26) in communication with a flow body (78). The speaker (26) emits an output for attenuating noise from the flow body (78). A control unit (31) communicates with the speaker (26) and controls the output. A housing (14) has one volume (18) acting as a liquid storage chamber and another volume (22) acting as a speaker chamber.
Claims18
An active noise attenuation system comprising:
- a speaker in communication with a vehicle's flow body, said speaker for emitting an output for attenuating noise from said flow body;
