Moths are under huge predation pressure from bats and have evolved a plethora of defenses in their strive for survival, but it&#8217;s the scales on a moth wing that hold the key to transforming noise-canceling <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>.<\/p>\n<p>Prof. Marc Holderied, of Bristol&#8217;s School of Biological <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a>s, said: &#8220;What we needed to know first, was how well these moth scales would perform if they were in front of an acoustically highly reflective surface, such as a wall.<\/p>\n<p>&#8220;We also needed to find out how the mechanisms of absorption might change when the scales were interacting with this surface.&#8221;<\/p>\n<p>Prof. Holderied and his team tested this by placing small sections of moth wings on an aluminum disk, then systematically tested how orientation of the wing with respect to the incoming sound and the removal of scale layers affected absorption.<\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/moth-wing-inspired-sou-1.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/moth-wing-inspired-sou-1.jpg\" data-sub-html=\"Close up of a wing scale.

The effect is also broadband and omnidirectional, covering a wide range of frequencies and sound incident angles.<\/p>\n<p>&#8220;What is even more impressive is that the wings are doing this whilst being incredibly thin, with the scale layer being only 1\/50th of the thickness of the wavelength of the sound that they are absorbing,&#8221; explained lead author Dr. Thomas Neil. &#8220;This extraordinary performance qualifies the moth wing as a natural occurring acoustic absorbing metasurface, a material that has unique properties and capabilities, that are not possible to create using conventional materials.&#8221;<\/p>\n<p>The potential to create ultrathin sound absorbing panels has huge implications in building acoustics. As cities get louder, the need for efficient non-intrusive sound mitigation solutions grows. Equally, these lightweight sound absorbing panels could have huge impacts on the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">travel<\/a> industry, with any weight saving in planes, cars and trains increasing efficiency in these modes of transport and reducing fuel use and CO<sub>2<\/sub> emissions.  <\/p>\n<div class=\"article-gallery lightGallery\">\n<div data-thumb=\"https:\/\/scx1.b-cdn.net\/csz\/news\/tmb\/2022\/moth-wing-inspired-sou-2.jpg\" data-src=\"https:\/\/scx2.b-cdn.net\/gfx\/news\/hires\/2022\/moth-wing-inspired-sou-2.jpg\" data-sub-html=\"Scale close-up.

Now the scientists plan to replicate the sound absorbing performance by designing and building prototypes based on the sound absorbing mechanisms of the moth. The absorption that they have characterized in moth wing scales is all in the ultrasound frequency range, above that which humans can hear. Their next challenge is to design a structure that will work at lower frequencies whilst retaining the same ultrathin architecture employed by the moth.  <\/p>\n<p>Prof. Holderied concluded: &#8220;Moths are going to inspire the next generation of sound absorbing materials. 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 gives moths stealth acoustic camouflage.&#8221;<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Moths and bats have been in an evolutionary battle for millions of years, and we&#8217;re still uncovering their tricks\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Moth wings as sound absorber metasurface, <i>Proceedings of the Royal Society A: Mathematical and Physical Sciences<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1098\/rspa.2022.0046\">DOI: 10.1098\/rspa.2022.0046<\/a>. <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/royalsocietypublishing.org\/doi\/10.1098\/rspa.2022.0046\">royalsocietypublishing.org\/doi \u2026 .1098\/rspa.2022.0046<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    University of Bristol<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.bris.ac.uk\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/phys.b-cdn.net\/tmpl\/v6\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Moth wing\u2013inspired sound absorbing wallpaper in sight after breakthrough (2022, June 14)<br \/>\n                                                 retrieved 15 June 2022<br \/>\n                                                 from https:\/\/phys.org\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-06-moth-winginspired-absorbing-wallpaper-sight.html<\/p>\n<p>                                            This document is subject to copyright.
