When does the noise change independent of engine speed?

Note that the question specifically states the noise is independent of engine speed – as long as the vehicle speed is above a certain point, the sound remains present and its pitch and volume are not affected when the engine speed changes independent of vehicle speed (e.g.: down-shifting while maintaining 60 MPH). – Iszi Oct 23 ’15 at 14:53
