Indian scientists develop noise control absorber mimicking beehives

It was developed by the faculties at IIT Hyderabad's Mechanical and Aerospace Engineering Department

An Indian research group has made a stronger polymer honeycomb and a paper honeycomb-structured sound absorbing panel which can dissipate acoustic energy to low-frequency ranges. This new technology can be used as an environmental noise control solution and also building acoustics.

 

Because of the geometry of the natural beehives have been found good at controlling high as well as low frequencies.

 

The Science and Technology Ministry said, "It has been found from theoretical analysis and experimental investigations that this behaviour was owing to the conversion of acoustical energy into vibration energy. This vibration energy is dissipated in the form of heat due to wall damping property. Mimicking this property as an engineering solution could offer a cost-effective method for controlling noise pollution."

 

It was developed by the faculties at IIT Hyderabad's Mechanical and Aerospace Engineering Department. The researchers were Dr Surya and Dr B. Venkatesham.
