Nowadays, due to the increasingly serious noise pollution, people also adopt some acoustic treatment methods to reduce indoor noise when they’re doing interior decoration, like installing sound absorbing boards. However, due to the lack of understanding of the sound absorption principle of acoustic panels, some wrong practices often occur. If not these problems and solutions will affect the final acoustic effect.

The errors that exist are as follows:

– The uneven surface is sound absorbing

In some decorations, people made the walls uneven, thinking that this would have the effect of absorbing sound. But there are two main ways of sound absorption: porous sound absorption and resonance sound absorption. Porous sound absorption requires material internal connected holes, and resonance sound absorption requires a cavity.

However, the uneven surface has neither internally connected holes nor cavities, so it is not sound absorption.

– As long as the soft package has sound absorption

In some decoration projects, a layer of composite soft fabric is often covered on the substrate. Although this method is a simple and decorative effect, it is not as good as people believe with a good sound absorption effect.

The acoustic performance of the sound absorbing board is closely related to the thickness of the acoustic panel. If the sound absorbing board is too thin, it cannot effectively absorb sound.

In general, if you want to achieve an ideal sound absorption effect, the thickness of the sound absorbing board must be at least 10mm, otherwise it cannot be used as an acoustic structure.

– Placement of sound absorbing board can sound absorb sound

In some decoration structures, the sound absorbing board is placed behind the plywood or gypsum board, so that the sound cannot enter the interior of the acoustic panel, then unable to produce the sound-absorbing effect.

These are some common misconceptions about sound absorption. In short, to get an excellent acoustic environment, consider using sound absorbing boards in the room. LEEDING polyester fiber acoustic panel is an ideal solution, not only high sound absorption performance, but also with good decoration, and reasonable price.
