ACOUSTICS PARTITION SPECIFICATION / DETAILS:
WHY IS IT REQUIRED?
An office is the centre of communication, thinking & collaboration. Any unwanted noise within an office is a major distraction and is a reason for employees not being able to achieve optimum productivity. Soundproofing are a necessity for offices, because apart from the noise within office interiors, there is a huge problem of unwanted noise from the exteriors such as traffic, construction, etc. which have the same unpleasant effect. The soundproof offices help in noise cancellation of this unwanted noise which intrudes the ‘thinking space’ of the employees.
Similarly, besides noise reduction, at times it is required to prevent certain discussions from being heard outside a cabin or conference room. Our state-of-the-art acoustic Office demountable glass partitions make sure that peace and tranquillity within office is maintained, and that important discussions remain confidential. Leakage of sounds comes from three common places
a) Common air space (Ceiling)
b) Mass & Density (Walls)
c) Hard surface (Floor)
HOW CAN WE SOLVE?
There are three methods of dealing with sound, commonly referred to as the ABCs. Sound can be absorbed, it can be blocked or redirected, and it can be covered. The method chosen depends on the final goal of the project.
Sound should be absorbedwhen the goal is to keep sounds within the room from reverberating or echoing. If a room has hard surfaces that reflect sound, it will take a long time for the sound level to diminish to a point that it is inaudible. This is most noticeable in an empty room with hard walls, floors, and ceilings: you can hear the sounds bouncing around the room. Installing sound absorbing materials, such as carpet, acoustic ceiling tiles, or fabric covered panels, will reduce the reverberation by absorbing the sound. Noise Reduction Coefficient, which is defined above, is used for rating a material’s ability to absorb sound.
If the goal is to keep sound within a space, for privacy or other reasons, the sound should be blocked. This can be combined with absorption so the reverberation in the space is reduced. Blocking sound is generally accomplished by reducing short circuits between two spaces. Common air space, is the FIRST path that sound uses, so this needs to be explored first, if you have a 5% air gap in any kind of a noise barrier, 90% of sound leaks through that air space. Some common features include HVAC ducts or grilles, back-to-back outlets, pipes that pass through a space, partitions that stop above the ceiling but do not extend to the structural deck above. Adding mass to the walls will help block the sound. For instance, a concrete wall blocks sound better than a stud wall. Additional layers of gypsum wall board and insulation in the wall cavity will also help block sound.
Sound can also be covered to help maintain speech privacy. This is most noticeable in an office environment when the forced air system is turned off, the idea is to provide just enough background noise to make nearby conversations unintelligible; the conversation is still there, but the quiet hum of the noise (soft music) masks it.
Note: It should be noted that on site acoustic test, a partition may provide 2dB to 6dB lesser performance compare to test done on laboratory conditions, it depends upon all the variable types of partition system available.
