Load corresponds to a broadband noise, slightly level, fluctuating, medium or high-frequency, and can be directive. A very turbulent flow would result in a flap-flap effect, also called load gust. A very directive flow is similar to a "leak". Load is a common sound, it can be likened to background noise, its level increases with vehicle speed, making it uncomfortable and it can worsen intelligibility. Prevalent above 80 km/h, it is produced by the turbulent aspect of the air flow that excites certain car equipment such as rear-view mirrors, pillars and windshields.
