What is an Electromechanical Relay?

Thanks for the comment! We hope you learned a lot from the video.

Relays may, when failing, result in an audible noise. This is often caused by the relay's coil and its inability to close the circuit.

So, would a malfunctioning relay make a horrible noise?
Because i believe I've traced the source of such a noise to one of 5 relays inside of my stereo receiver.
