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 ...

The attenuation of low-frequency sound has been a challenging task because the dynamics of dissipative systems are generally governed by the rules of linear response, which dictate the frictional ...

(Phys.org)—A team of researchers at Hong Kong University of Science and Technology has found a way to create a material that is near perfect at preventing sound waves from passing through it. In their ...

Heriot-Watt University is the only site in Scotland participating in satellite data collection as part of a landmark five-year experiment with NASA and the European Space Authority (ESA). Dr George ...

Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers ...

A listening room, defined by its dimensions, can be mapped in terms of a series of pressure peaks and nulls, in all three dimensions. This refers to the creation of standing waves (modes), and the ...

Whether it’s audio, video, post, or editing, one aspect of good control room design involves the proper use and placement of acoustical materials, primarily absorbers and diffusors, and sometimes ...
