The International Code Council (ICC) rating of a material is used to assess its ability to prevent airborne sound transmittance. This rating is determined by a “hammer machine” on the upper floor and by measuring the sound in decibels in the lower room. The STC rating is a logarithmic measure of the loss of sound transmission between two rooms, measured at 16 frequencies, from 125 Hz to 5000 Hz. When selecting flooring for a particular application, it is essential to consider both the ICC and STC ratings of the material.
Carpets may be suitable for classrooms, but they would not meet the sanitary standards used in an operating room. Combining carpet with resin flooring can help isolate sound where it is needed most. To further improve acoustic performance, an acoustic subfloor should be installed between the wooden planks and the subfloor. Acoustic panels are effective in absorbing sound waves and can also be decorative.
If your acoustic wall panels are wrapped in fabric, they likely use Guilford of Maine acoustic fabric or something similar. Floating wooden floors require an acoustic base for optimal performance. This base layer should be dense enough to absorb sound waves, yet elastic enough to provide comfort compared to harder materials. Along with ceiling and wall coverings, an acoustic floor system will help create the best acoustic environment for your building application. When selecting an acoustic base for your flooring, it is important to consider the type of material you are using and its STC rating.
For example, if you are using a carpet, you may want to choose a thicker underlayment that will provide more insulation against sound transmission. If you are using a hardwood floor, you may want to choose a thinner underlayment that will provide more cushioning and comfort. It is also important to consider the size of the room when selecting an acoustic base. If you have a large room, you may need a thicker underlayment that will provide more insulation against sound transmission. On the other hand, if you have a smaller room, you may need a thinner underlayment that will provide more cushioning and comfort. Finally, it is important to consider the type of environment you are creating when selecting an acoustic base.
If you are creating an environment that requires high levels of sound absorption, such as a recording studio or theater, then you may need a thicker underlayment that will provide more insulation against sound transmission. On the other hand, if you are creating an environment that requires low levels of sound absorption, such as a home office or bedroom, then you may need a thinner underlayment that will provide more cushioning and comfort.
