What is the sound of a tea kettle not boiling?


Before a kettle of water begins to boil it makes a popping and high pitched sizzling sound. I've looked inside and there isn't any boiling going on yet (no bubbles). So is the sound coming from the expanding kettle or the water or somewhere else (like my fragile psyche). Please tell me so that I might look even smarter in front of my wife.
Thank you,
