Control of wind noise for road vehicle with open windows involves sensors for degree of opening of windows and ventilators and manual controls specifying amount of ventilation required

摘要

The system includes sensors determining the amplitude of the wind noise and also the frequency distribution of the noise. An on-board computer has a memory containing details of noise profiles for various settings of ventilators and windows. Actual and recorded values of settings may be compared. Various noise settings may be used, including 'normal', 'murmuring', 'sporty', rapid, or 'extreme'.
