Imagine a world where you can effectively block sound without the need for bulky and sometimes costly insulation. A game-changing technology is making this possible – a unique material that can block ...

June 26 (UPI) --Scientists have developed a superior sound-reflecting material. The "retroreflector" technology can bounce back sound waves in the direction they came from. Previous retroreflectors ...

If you’re keen on finding some soundproofing materials that actually work, you’re not the only one. Silence is golden for so many of us: DIYers who use loud tools, night-shift workers who must reduce ...

“The idea is that we can now mathematically design an object that can block the sounds of anything,” researcher Xin Zhang said in a press release — meaning the future could be far quieter than the ...

It is well understood that, given an arbitrary geometric transformation of a sound field, the effective mass density and the bulk modulus required to implement that transformation is determined as ...

Acoustical comfort is a critical element of interior design that should never be neglected, especially in shared spaces such as restaurants, convention centers, museums, sports halls, and many others.

Metamaterials researchers have created a thin plastic structure with geometric details allowing it to control the redirection and reflection of sound waves with almost perfect efficiency.

So far we have only considered sound in isolation and we have seen that sound has velocity, frequency, wavelength and reduces in intensity in proportion to the square of the distance from the source.
