Heavy curtains made from thick material such as velvet are often needed to keep noise out of indoor environments, but Swiss researchers have come up with another option. The Empa researchers, in ...

Absorbing low frequency sound is a big job, or at least, a job for big things. Acoustic absorption systems require big resonant cavities with large amounts of heavy damping material and significant ...

Experts at the University of Bristol have discovered that the scales on moth wings act as excellent sound absorbers even when placed on an artificial surface. The researchers, which recently ...

This latest accomplishment joins the company’s previously secured ASTM certifications, enhancing the features and expanding the end-uses for its microalgae-based bio-cement and bio-concrete. BOULDER, ...

In case you’re sensitive to noise and look for a discreet way to solve the problem in your apartment or office building, for example, the so-called Feltone [JP] might do the trick for you. Developed ...

Sound absorption Incoming acoustic waves induce relative movements among the fibres, initiating the triboelectric effect within overlapping regions. The generated charges are dissipated through ...

Bad audio can seriously harm an otherwise strong video. But recording good audio can be a daunting task. It’s not just about having the right microphone, as the environment itself has a big effect on ...

When it comes to low-frequency sound waves, traditional sound-absorbing materials tend to be undesirably bulky, heavy or thick. Now, researchers have designed subwavelength absorbers specifically for ...
