Electric Whistling corresponds to a high or very high frequency sound, emergent and directive. It is very commonly absorbed within the "whining" sound due to its motor-harmonic and emergent behavior, despite being higher and having a slightly different behavior. Its high frequency and directive aspect recall "aeroacoustic whistling", even though electric whistling is judged more acceptable and more coherent with the electric vehicle, but it is still considered annoying and bothersome. Electric whistling is mainly due to electric machine functioning and vibrations induced by its electromagnetic fields.
