Why do I hear electric sounds?

The audible noise emitted from high-voltage lines is caused by the discharge of energy that occurs when the electrical field strength on the conductor surface is greater than the ‘breakdown strength’ (the field intensity necessary to start a flow of electric current) of the air surrounding the conductor.

Why does my car make a lot of noise?

Especially when the motor starts from its stalled position, comparably higher current, or a stall current, flows into the windings. Higher current usually causes higher noise. the input to the motor is much higher than expected and so on.
