Abstract
A wind noise throb reduction system includes a controller configured to reduce wind noise throb, an active noise cancellation subsystem responsive to the controller and a dynamic airflow control subsystem responsive to the controller. A related method of reducing wind noise throb in a passenger compartment of a motor vehicle is also provided.
Claims18
A wind noise throb reduction system for a motor vehicle, comprising:
- a controller configured to reduce wind noise throb and to include a first data input for sound pressure data;
- an active noise cancellation subsystem responsive to said controller;
- and
- a dynamic airflow control subsystem responsive to said controller.
1 more element
A method of reducing wind noise throb in a passenger compartment of a motor vehicle, comprising:
- monitoring, by a window position monitoring device, motor vehicle window position;
- monitoring, by a sound pressure monitoring device, sound pressure in said passenger compartment;
- generating, by an active noise cancellation subsystem, an active noise cancellation signal;
- and
- displacing, by a dynamic airflow control subsystem, a dynamic surface on said motor vehicle to direct airflow away from an open window only when wind noise throb still exceeds a threshold level following generating said active noise cancellation signal.
