“They fly without a noise”: the secret of the owls inspires a material capable of stifling the most violent sounds

In a world where the constant noise of engines. For example, circulation invades our lives, the quest for effective solutions to reduce this incessant din has become essential. However, Inspired by the silent flights of owls, researchers have developed an innovative material capable of considerably reducing noise pollution. Similarly, Thanks “they fly without noise”: secret to the combination of science. Nevertheless, biomimicry, this advance promises revolutionary applications in various industrial sectors, offering a more serene and less noisy future.

Science behind the silent flights of owls – "they fly without noise": secret

The owls. Moreover, masters of silent flight, have natural adaptations which allow them to move without noise, a crucial asset to capture their prey. Nevertheless, Their specialized feathers, with serrated edges, disturb the flow of air turbulent, making the vortices of air smaller and quieter. Moreover, This unique ability to absorb sounds of different frequencies makes owls natural experts in soundproofing. Similarly, By drawing inspiration from this characteristic. researchers from Tiangong University in China have designed a new double -layer aerogels, capable of absorbing 58 % of sound waves, thus exceeding current noise control standards.

This innovative material could find applications in reducing the noise of cars. factories, thus offering an alternative to traditional methods of combating noise pollution. “they fly without noise”: secret Biomimetic owl technology could transform our approach to noise controlmaking our environment more peaceful.

A double layer material to reduce noise – "they fly without noise": secret

The creation of effective soundproofing materials has long fascinated scientists. especially due to the exceptional capacity of owls to fly silently. The new research has focused on reproducing the exact structures present in the feathers and the skin of the owls. “they fly without noise”: secret The developed material consists of a porous lower layer. an upper layer inspired by feathers, made of silicon nanofibers, intended to alleviate sounds of various frequencies.

This innovation offers a light and efficient solution to reduce noise, thus resolving the limitations of traditional materials. Standard felt fiber materials often manage to absorb high or low frequency sounds. On the other hand. this aerogels inspired by owls is capable of managing a broad sound spectrum, while remaining light and durable. This development opens up new perspectives in terms of noise reduction, particularly in the transport and industry sectors.

Reduction in car noise

Traditional soundproofing materials used in vehicles often have. significant limits. They generally only manage to absorb either acute sounds. such as the brake screech, or deaf rumble, such as the noise of truck engines. This forces engineers to use several layers, which increases solutions and makes them bulky.

On the other hand, the aerogels inspired by the owls offers a more efficient and light approach. With its double layer structure, it manages to reduce the deafening roar of an automobile engine of 87.5 decibels to a “they fly without noise”: secret safer level of 78.6 decibels. This reduction exceeds that of many high -end noise absorbers available on the market. In addition, its durability is remarkable because it retains its structural integrity after 100 compression cycles with minimal deformation. This advance promises to transform the way we approach the problem of noise pollution in the automotive sector.

The impact of sound pollution on human health

Noise pollution is not limited to being a simple nuisance. It represents a real danger to human health. Prolonged exposure to high sound levels can cause permanent hearing loss. In addition. it can worsen existing medical 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 precious opportunity to mitigate these risks by effectively reducing environmental “they fly without noise”: secret noise. By improving our quality of life. these sound solutions could play a crucial role in prevention of health problems related to noise, making our world not only quieter, but also healthier.

While advances in biomimetic technology continue to progress. what will be the long -term impact of these materials inspired by owls on our society and our environment?
