By Ming-Han Ho (何明翰)

A kitchen hood containing fans that hangs on the top of stove or cook top in kitchen. It removes airborne grease, combustion products, fumes, smoke, odors, heat, and steam from the air by filtration. Kitchen hood noise is a complex noise which is generated by each mechanical components inside the kitchen hood. ANC technique is implemented to create a quiet zone surrounding the cooker’s head. The noise reduction can be up to 6 dB, and can be further increased with more advanced algorithms and fine tuning.
