Abstract: A system for actively mitigating a buffeting noise in an occupant compartment of a vehicle when the vehicle is moving. The system is configured to determine an estimated effective volume of the occupant compartment, and to determine if a single window of the vehicle occupant compartment is open. Responsive to a determination that a single window of the vehicle occupant compartment is open, and using the estimated effective volume of the occupant compartment, an estimated buffeting noise frequency is determined. Responsive to the estimated buffeting noise frequency, the system determines characteristics of a sound configured to cancel a buffeting noise generated inside the occupant compartment while the vehicle is moving. The system may then control operation of a noise cancelling signal generating system to generate the sound having characteristics configured to cancel the buffeting noise inside the occupant compartment.

Abstract: An omni, bollard speaker has circular, cylindrical lower and upper housings. A domed driver is mounted within the top wall of the lower housing and a speaker is rotatably mounted in the internal space in the upper housing, between the top wall of the lower housing and the speaker cover of the upper housing. The speaker is rotatable from a first horizontal position directly over the domed driver to reflect wide dispersion acoustical output directly over the driver to disburse sound evenly within the listening area. The speaker can be quickly rotated downward and converted from this down-firing omni reflecting position to a side firing position or an up-and-out, direct radiating position. Thus, the same speaker serves many different sound coverage applications and can be customized on site for best use.
