Often, when watching a movie or loud music, we encounter buzz at certain points in the room. This effect is called "resonance" or "standing wave".
Such effects arise due to the superposition of two reflected waves, the amplitude of which increases at least twice.
Such effects are often subject to low frequencies due to their wavelength, and they need to be dealt with as with higher frequencies.
The effect of "resonance" is often observed in the corners of the room and under the ceiling, since it is easiest for a wave to double its amplitude due to reflection at the junction of two surfaces.
To solve such problems, they usually offer several diffusers tuned to the same frequency or complex designs that require complex installation and the presence of a specialist to properly configure such devices.
A simpler and no less effective method of dealing with low frequencies are bass traps made of acoustic foam rubber. Due to their lightness and shape, they can be installed quite easily by one person and transform annoying buzz into thermal energy.
Bass traps are most often installed in the corners of the room using special glue or very strong double-sided tape. For accurate acoustic correction, you can also install bass traps on racks, which will allow you to easily change the position of the absorber at any time and put it in the most problematic place.
By using Bass Traps in conjunction with Corner Cubes, you will increase the effectiveness of your sound deadening structures.
Acoustic panels are known to be effective at medium and high frequencies, but cannot effectively absorb low frequencies due to their thickness and shape. However, when using the bass trap along with other acoustic panels, you will get uniform absorption of the entire sound range.
