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 Childcare and daycare
settings where sound transmission to other areas is a
problem. The use of composite materials that have 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. Another Problem area is floor-to-floor
sound transmission, which usually involves adding composite
materials or underlayment materials that block sound and
or vibration.
Sound Absorption has become a very important in Childcare
and Daycare facilities. These areas are typically reverberant
and 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 pleasant learning
environment. 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 has a good NRC at your offending frequency.
