“Flying without noise”: The secrets of the owl inspires the material capable of suppressing the most violent sounds – the environment

In a world where the constant noise of engines and circulation attacks our life, there has been a necessary effort to effectively solve this continuous DIN. Scientists, inspired by the silent flights OWL, have developed innovative material capable of significantly reduce noise pollution. Thanks to the combination of science and biomimicry, this progress promises revolutionary applications in various industries and offers a quieter and less noisy future.

Science for quiet flights of owls

Owls, the Masters of Silent Flight, have natural adaptations that allow them to move without noise, which is essential to capture their prey. Their specialized feathers with serrated edges disrupt the air flow of the air turbulent, so that the air beliefs are smaller and quieter. This unique ability to absorb the sounds of different frequencies causes owl natural experts on sound ooles. By creating an inspiration from this characteristic, scientists from Tiangong University in China designed a new double -layer double -layer, which is able to absorb 58 % of sound waves, exceeding the current noise control standards.

This innovative material could find applications when reducing car noise and factories, offering an alternative to the traditional methods of combating noise pollution. Biomimetic owl technology could transform our noise control approachmake our environment calmer.

Double -layer material to reduce noise

Creating efficient sound materials has long fascinated scientists, mainly due to the exceptional capacity of the owl to fly quietly. New research focused on the reproduction of the exact structures present in the feathers and the skin of the owl. The developed material consists of a porous lower layer and upper layer inspired by feathers made of silicon nanofibers, designed to alleviate the sounds of different frequencies.

This innovation offers light and efficient noise reduction solutions to solve the reduction of traditional materials. Standard felt fiber materials often can absorb high or low frequency sounds. On the other hand, these aerogels inspired by OWL are able to drive a wide sound spectrum, with light and durable. This development opens new perspectives in terms of noise reduction, especially in the transport and industry industry.

A reduction in car noise

Traditional sound materials used in vehicles often have significant limits. In general, they can absorb either acute sounds such as a brake scream or a deaf rumble, such as noise of truck engines. This forces engineers to use several layers, which increases the solution and makes them bulky.

On the other hand, Aerogels inspired by OWLS more efficient and lighter approach. With its double layer structure, 87.5 decibels are reduced to a safer level of 78.6 decibels. This reduction exceeds the reduction of many noise absorbers with a high end available on the market. In addition, its durability is remarkable because it retains its structural integrity after 100 compression cycles with minimal deformation. This procedure promises to transform the way we approach the problem of pollution by noise in the automotive sector.

The impact of sound pollution on human health

Noise pollution is not limited to being a simple harassment; It represents a real danger to human health. Long -term exposure to a high level of sound can cause permanent hearing loss. In addition, it can worsen existing health conditions and contribute to the development of new diseases such as cardiovascular disease, including high blood pressure and increased risk of heart attack, as well as metabolic disorders such as type 2 diabetes.

Innovative materials inspired by owls offer a rare opportunity to alleviate these risks by effective environmental reduction. By improving our quality of life, these sound solutions could play a key role in preventing health -related health problems, so our world will be not only quieter but also healthier.

Although progress in biomimetic technology still proceeds, what will be the long -term impact of these materials inspired by owls on our society and our environment?
