U.S. startup Ko-Solar and Germany’s R. Kohlhauer, announced plans to offer turnkey PV-integrated noise barrier systems for ...

Noise reduction techniques don’t have to be expensive or complex. Small, intentional changes — like sealing a window, laying down a rug or hanging thick curtains — can bring significant relief.

Researchers at the Swiss Federal Laboratories for Materials Science and Technology (EMPA) have developed an ultra-thin traffic noise absorber that significantly reduces sound levels while occupying ...

Looking for attractive wallpaper that cuts down the noise? Sound reducing technology has come a long way, but make sure you ...

In terms of the perception of noise in the space, that’s a 60% reduction. [Photo: NBBJ + University of Washington] “We can’t ignore the human voice.

Full enclosures will enclose the machine on all sides. These provide greater noise level reduction — up to 20 to 30 decibels — but can be more challenging to design. A full enclosure will probably ...

Absorb 58% of soundwaves that strike it, surpassing the threshold for effective noise control materials. Reduce 87.5 decibels of automobile engine noise to a safe level of 78.6 decibels, which is a ...
