I don't profess to be an acoustical engineer or some sort of sound guru. I'm a normal guy, married with a kid, who has recently purchased my first house. I've been an audio nut for years with very ...

Many asymmetric absorbers are currently based on a single-port system, where sound enters one side and is absorbed before a rigid wall. In this design, however, light and air are unable to pass ...

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. Experts at the University of Bristol have ...

Continued from Part I … So the big question - How do they work? In my opinion - great. The difference in my room is dramatic. I don't have any fancy measuring devices (only my SPL from radio shack) so ...
