Moth wings could be used to curate sound-absorbing wallpaper- Study

According to a recent analysis and research it has been observed that moths have been under huge evolutionary pressure to develop defence to survive. And in this regard, the little scales on their wings are one of these adaptations that hold the key to transforming forthcoming noise-reducing technology.

Marc Holderied, Sensory Biology Professor in the School of Biological Sciences, University of Bristol stated that moths are true inspiration for the next generation of sound-absorbing materials.

Marc mentioned that latest research demonstrates that there is a possibility of developing an ultra-thin sound-absorbing wallpaper by using a design similar to the mechanism that provides moths stealth acoustic camouflage.

As per sources, the research earlier demonstrated that the wings of the moths provide safety from bat echolocation via porous nanostructure scales on their surface that absorbs sound.

For the record, the scales on the wings of the moths are 1-2 microns thick and nearly 100-200 microns long which indicates that they don’t bounce sound waves back to the bat. They rather vibrate and convert the sound into kinetic energy.

According to reports, scientists have studied if this structure can inform the design of mounted sound absorption, by assessing the ability of the moth wings to a surface to absorb sound.

Marc further quoted that it needs to be figured out how well the moth wings will perform if they were placed in front of an acoustically high reflective surface like a wall.

Furthermore, it was reported that the team would also be studying on how the mechanism of absorption might evolve when the scales come in contact with this surface.

Through this research it was observed that the wings absorbed 87 per cent of the incoming sound energy when placed on top of a solid surface, along with absorbing wide range of frequencies coming from various angles.

It has been speculated that the creation of this material could potentially be used in both the building industry and travel.
