Sound Blocking/Barrier products typically
involve mass. These products help block noise from traveling
from one area to another. Sound Blocker/Barrier Products
carry a comparative STC number that reflects the approximate
Dba reduction with use of that product.
Remember - anything water can pass through - sound could
pass through. These products can be of use in offices
where sound transmission to other rooms is a problem.
The use of composite materials that has a layer of barrier
material with the addition of at least one layer of absorption
material is also a nice solution that can block and absorb.
Products are also available to block sound where floor-to-floor
sound transmission is a problem in office areas. Sound
Masking is also a great option for open office(cubicle)
settings to maintain speech privacy and increase speech
intelligibility.
Sound absorption products can be a very important element
in Office areas. If these areas are reverberant they
need to have special attention paid to absorbing the
reflection off hard surfaces.
To
increase speech intelligibility and perceived noise reduction
- sound absorption products make for a more accurate listening
experience. Absorbing products are typically porous products
that help knock down reverberation off hard surfaces.
These products carry an NRC number that is a comparative
number telling what percentage of reflection is absorbed
at certain frequencies. it is best to choose a product
that bas a good NRC at your offending frequency.
