Acoustic Felt for a Quiet Office Space

Feb. 05, 2021

One of the key design principles of today's smart office environments is to create a rich variety of functional areas within an open office space to support different types of work styles. However, while an overly open space has the advantage of light and visibility, it also reduces personal privacy and creates a lot of noise nuisance. This is where colorful acoustical felt can not only help to solve the problem, but also provide an unexpected decorative effect.

 

Acoustic felt, because of its easy production process and rich decorative, can efficiently convey the designer's intention to help create the atmosphere. Whether hanging or floor standing, they can be freely reorganized and changed according to the needs of the environment. A set can be placed in an open work area to define the space and create a private space.

In an open work area, we need some quiet informal space to support short, focused, individual or two or three person tasks, while still being able to change configurations at any time to meet the needs of the team working. Acoustic partition screens can easily achieve such a vision. Whether it's a flat sculpture, a three-dimensional process, or a modular combination of individuals, these creative acoustic products will inspire designers to.


What is acoustics?

Acoustics refers to the study of the generation, propagation, reception and effects of sound waves. And we often say that sound (sound) is the sound waves generated by the vibration of objects, is through the medium (air or solid, liquid) propagation and can be perceived by the human or animal hearing organs of the fluctuation phenomenon.

When it comes to architectural acoustics, we have to talk about materials and structures.

Sound-absorbing materials, I explain here, sound absorption is not really the sound to be absorbed, but when the sound waves in the transmission process encounter obstacles or from the porous material into, causing internal vibration, sound energy into heat energy is consumed, that is, to achieve the so-called sound absorption effect.

Common absorption materials are porous materials, plate materials, perforated panels, molded ceiling acoustic panels, membrane materials, flexible materials. The most dominant material is porous material. Porous material pringting acoustic felt itself has good absorption of high and medium frequencies, and also absorbs when there is an air layer left behind.

Myth 1: We often say that the concept of good sound absorption of rough walls is correct?

Porous acoustic materials have good sound absorption performance is not because of the roughness of the surface, but because porous materials have a large number of tiny voids and holes connected inside and outside, sound waves into the cavity with the air and pore wall friction and heat conduction effect, sound energy is consumed.

So only holes open to the outside, holes straight interconnected, and deep inside the material, can effectively absorb sound energy. We often say that rough walls, such as brushed concrete and wallpaper do not meet this requirement, so this understanding is wrong.


Misconception two: we commonly used insulation and insulation material voids and cavities are also very much, it can also achieve the effect of sound absorption?

Commonly used thermal insulation materials and sound-absorbing materials have different requirements, such as polyphenylene and part of PVC foam, and aerated concrete materials, which also have a large number of internal pores, but most of them are closed individually and not connected to each other, they can be used as thermal insulation materials, but the sound-absorbing effect is not good.
