Try to narrow the source down. Put ear by burner
opening. Could be normal sound of gas in pilot.

Could be a very small water leak too. If the leak is
in the central flue of the tank, you won't see any
water as it will be carried up the flue. But a leak
in the tank can mean impending failure.

Also, check the temperature/pressure relief valve. It might be
leaking for a variety of reasons.

Turn the heater off. Does the sound continue? That might help
diagnose it.
