Choosing The Optimal Sound Absorption

August 14, 2017

Rooms with sound-absorbing ceiling

For certain environments, a sound-absorbing ceiling alone is not sufficient to create acceptable room acoustics. Indeed, new findings show that not only is it important to reduce the reverberation time, but also to reduce the sound pressure level as a whole. Accordingly, additional surfaces like walls can come in to support more sound-absorbing elements. A multitude of environments can benefit from an optimal sound absorption: day-care centres, schools, banks, and other open plan office spaces to name a few. As a result to increasing the amount of sound-absorbing material, the room acoustics would reach an optimal level.

In some cases, the architecture of the room can play a part in the relevant choice of sound-absorbing material. For example, it might be difficult or inappropriate to use the ceiling area, or perhaps only parts of the ceiling can be used. In one occasion, the original ceilings in older buildings might have attractive artwork or  precious ornamental plaster. Similarly in modern buildings, the architect or designer may decide for the ceiling installations such as concrete or thermal systems to be visible as part of a minimalist design.

Added benefits with vertical absorbers

With regards to the above, some premises would then require various acoustic material in order to reduce the noise levels. And the more sound-absorption there is in a room, the lower the noise level will be. Interestingly, studies showed that less noise in a room also results in additional sound reduction when it normally facilitates a psychological reaction: people talk more quietly.

As a solution, the most straightforward application to reduce sound pressure levels is to install wall panels as a continuous wall-to-wall or to partly cover a wall. From the acoustic point of view, it is ideal to cover at least two perpendicular walls, in full or partially. In this case, you’re treating both of the horizontal sound fields and successfully avoiding the flutter echo.

Among our range of sound acoustic textiles, we recommend the Silencio 5 coupled with our acoustic fleece. Bored of bland colours? With HP Latex you can print on this textile to make it as personalized as you need.
