If it only makes noise when water is flowing it is coming from the check valve.

That's the only moving part in WH.
If it makes noise while heating using the electric element...element is coated in calcium/scale
Air pocket is suppose to be there to allow for the expansion of the water as it heats so high pressure is not built up.
Turn off water heater
Turn off water supply
Open faucet hot side to relieve pressure
OPEN PRV via lever.hold open until water stops flowing then let if snap shut
Close faucet
Turn on water supply
Air pocket re-established.
