Case Study: Active Noise Control Reduction in Range Hoods

In range hoods, a blower is typically used to move air through the system, which is the most significant source of noise.

 

 

The European Union and many other jurisdictions are setting targets for quieter electrical equipment.

 

Therefore, the development of products based on active noise control is becoming increasingly necessary.

 

As a typical air-moving device, the range hood possesses three noise sources:

• Air Inlet
• Air Outlet
• Body

These three noise sources differ in their noise levels, their spectra and in their characteristic paths (airborne or structure borne).

 

The ANC components – speaker, microphone and Silentium S-Cube™, located inside the chimney hood – reduce the noise emitted from the inlet.

 

The S-Cube is a low–cost, basic building block for implementing an active acoustics control solution for mass-produced products, significantly reducing broadband noise and vibration.
