The noise could be one of two things:

1: The container you are cooking in may be resonating with the motor creating a unpleasant sound.
2: The Joule Unit has Limescale built up from cooking at higher temperatures or using hard water. To fix this place joule in small vessel and add a 1:1 mix of water and distilled vinegar. Bring unit to 140F. This should take care of noise.
