摘要： A vehicle air supply noise attenuation system utilizes both active and passive methods of noise attenuation. A helmholtz resonator communicates with an air supply duct, and is designed to attenuate a narrow band of noise. An active noise control system, including a speaker and an electronic controller, is mounted within the resonator volume and attenuates noise over a wider band of frequencies. The combination of the active and passive noise control attenuates noise over a wide band of frequencies without requiring an overly large speaker.

摘要： An active noise attenuation system for an air induction assembly includes a housing that is mounted to a vehicle structure and a speaker assembly that is mounted within the housing to generate a sound field for attenuating noise. The housing defines an air inlet duct open end through which air is drawn. A microphone detects noise and modifies an anti-noise signal that is sent from an electronics center. The electronics center receives the signal, mixes with other engine signals, phase-shifts the signal, and sends the phase-shifted signal to the speaker to attenuate the noise. The speaker includes electrical connections that extend outwardly toward the air inlet duct open end for connection to the electronics center. The microphone and speaker are connected to the electronics center with flex cables.

摘要： The method of noise attenuation comprises the steps of generating a noise canceling signal, sensing for an system condition, and ceasing the generation of the noise canceling based upon the system condition. This method is embodied in a system that includes an air induction body, a speaker in proximity to the air induction body, a sensor for sensing a system condition, and a control unit with a noise cancellation feature. The control unit is in communication with both the speaker and the sensor. Based upon the sensed system condition, the control unit may disable the noise cancellation feature.

摘要： A vehicle air intake system includes a noise cancellation assembly. A cooling member is provided at least partially within an air passageway for dissipating heat within an electronics module portion of the noise cancellation assembly. The cooling member preferably is a brass material insert that is supported at least partially within an air passageway by a housing that supports components of the noise cancellation assembly. A connecting member that thermally couples the electronics module to the cooling member also operates to secure the electronics module to the housing in one example embodiment.
