, the need for such efficient, non-intrusive, sound mitigation solutions grows. These lightweight sound-absorbing panels could have massive impacts on the travel industry, with weight saving in planes, cars, and trains increasing efficiency in these modes of transport, reducing fuel use and CO2 emissions. building prototypes based on the sound-absorbing
mechanisms of the moth. Currently, the absorption that they have characterized in moth wings is in the ultrasound frequency range. Their main challenge is to design a structure that will work at lower frequencies whilst retaining the same ultrathin architecture employed by the moth. "New research has shown that one day it will be possible to adorn the walls of your house with ultrathin sound absorbing wallpaper, using a design that copies the mechanisms that give moths stealth acoustic camouflage.
