Helmholtz Resonator

What is a Helmholtz resonator?   The Helmholtz resonance is named after Hermann von Helmholtz, who created a resonator device in the 1850s. He used to identify the various frequencies and musical pitches present in music and other complex sounds. Helmholtz...

Ceiling Clouds

What are Ceiling clouds?   Ceiling clouds (or tiles) are a type of soundproofing objects. Producers and sound engineers use them in music production studios as well as in other spaces to effectively reduce reflected sound in large and open environments as well as...

Reflection Filters

What is a reflection filter?   The reflection (also known as pop shield or pop screen) filter is the type of product whose purpose is to provide some helpful absorption of sounds that would otherwise reach the rear-facing sides of the mic.  Also, it catches and...

Acoustic Foam

Acoustic foam   Next, to fibreglass, acoustic foam is one of the most widely used materials for soundproofing. It is a cost-effective absorber, and a meter-square area of such treatment covering each of the reflection points can make a big difference to the...

Resonance Absorbers

What are resonant absorbers?   The resonant absorbers are frequency-dependent because of the desired resonance of the material at a particular wavelength. Different types of resonant absorbers are the Salisbury screen, the Jaumann absorber, the Dallenbach layer,...

Acoustic Board

What is an acoustic board?   An acoustic board is a special kind of board made of sound absorbing materials. Between two outer walls sound absorbing material is inserted and the wall is porous. Thus, the intensity of sound decreases when sound passes through an...
