The Chinese oak silkmoth. Moths’ scaled wings offer acoustic protection from bats’ echolocation calls

T he amazing sound-absorption abilities of moths’ wings, which helps them evade bats echolocation calls, has inspired new techniques for manufacturing ultra-thin sound absorbing panels.

Scientists at the University of Bristol discovered that the minute scales which cover moths’ wings can act as excellent sound absorbers even when placed on artificial surfaces – rather than when they are moving in free space.

They said the discovery could "hold the key to transforming noise-cancelling technology".
