First Claim
Patent Images
1. A wind noise reduction apparatus for a motor vehicle, comprising:
- a mirror housing;
a mirror held in said mirror housing;
a control module including a controller, said control module configured to displace said mirror housing to reduce wind noise and displace said mirror to maintain a constant visual field as said mirror housing is displaced in response to sound pressure in a passenger compartment of said motor vehicle exceeding a predetermined threshold level indicative of at least one of wind noise, wind noise throb and wind buffeting experience through an open window; and
a sound pressure monitoring device providing sound pressure data from said passenger compartment to a data input of said controller.

6. A method of reducing wind noise in a passenger compartment of a motor vehicle, comprising:
-
monitoring, by sound pressure monitoring device, current sound pressure in said passenger compartment of said motor vehicle; displacing, by control module, a mirror housing carried on said motor vehicle to reduce wind noise; and displacing, by said control module, a mirror held in said mirror housing in order to maintain a constant visual field in said mirror as said mirror housing is displaced; and configuring a controller of said control module to displace said mirror house to reduce wind noise and displace said mirror to maintain the constant visual field as said mirror housing is displaced in response to current sound pressure exceeding a predetermined threshold value indicative of at least one of wind noise, wind noise throb and wind buffeting experienced through an open window. - View Dependent Claims (7, 8, 9)
