Abstract
A food waste disposer system () has active noise control of food waste disposer noise that is generated by the food waste disposer () when a motor of the food waste disposer () is running. The food waste disposer () has a food conveying section that conveys food waste to a grinding section. The grinding section has a rotatable shredder plate that is rotated by a motor of a motor section. Active noise sound waves () are radiated into an area () where the food waste disposer noise is to be controlled at an amplitude and frequency to at least cancel or mask the food waste disposer noise.
