Porous Absorbers

Porous absorbers are a treatment for acoustic problems, as well as to reduce noise and resonance. To understand how they work, we must first look into the physics of it all. The Physics of Porosity Due to viscous boundary layer effects, when a sound spreads in a small space, it loses energy. It can lose…

Membrane Absorbers

Membrane absorbers, also known as panel and diaphragmatic absorbers, use the resonant qualities of a membrane to take in sound over a narrow frequency range. Their composition is of pressed wood fibers and soft panels, as well as rigid or semi-rigid materials like plastic. When mounted on a solid wall and separated by a narrow…

Resonance Absorbers

Resonance absorbers, also known as tuned traps, pressure absorbers, or narrowband absorbers, are devices that are frequency-dependent. This is because of the desired resonance of a particular material at a specific wavelength. There are several types of resonance absorbers. Some examples are the Jaumann absorber, the Salsbury screen, and the Dallenbach layer. In addition, there…

Monitor Isolation Pads

Monitor isolation pads are pads that decouple the monitor from the surface. These devices are made of dense acoustic foam and metal spikes on which the speakers rest. The pads isolate the monitor from the stand making sure that the speaker operates in an independent way with no additional vibration. In addition, they also prevent…
