Well said, steved. Also, hissing is not pinging. A ping sounds like someone striking an anvil with a ball peen hammer. If you hear a lot of pings in a row it can sound like an unbalanced washing machine in a spin cycle.
Hissing usually indicates intake air and exhaust gas movement. I've heard the 1NZ-FE engine produce a hiss under WOT (wide open throttle) in a high load scenario, which is just air moving into and throughout the throttle body.
