Leak is a very fluctuating and very directive sound, rather high-frequency and high in level. It emerges from a background noise and is characterized by narrow band instead of broad band noise. It is in particular more directive, more high-frequency and more identifiable but less fluctuating than "load". It is more fluctuating and as emergent as "aeroacoustic whistling". Its directivity and its level, which depend on vehicle speed, are annoying if not unacceptable of Leak. It spoils the cocoon effect, the reassuring and insulating aspect of the cabin. Leak is a sound of aerodynamic origin, caused by a failure inof airtightness.
