The answer to this is dependent on the size of your room.   The larger the space, the more square footage of product will be needed in order to trigger the sound values you are after.   We are careful to not under treat the space and force a decay in your results.  A simple Room Analysis can be performed to help calculate the coverage appropriate for your soundproofing treatment.

The answer is also dependent on the frequency of the noise source.   The lower the frequency of the noise is (low bass noise such as guitars, drums, engines), the thicker the panels should be to properly attack the low frequency sound.  The thicker the panel, the more expensive the square foot price.

So room size, and noise source frequency, will both combine to produce the calculation required for you to meet your soundproofing objectives.   Once your noise source and room dimensions are defined, a quick calculation can be run to determine your coverage needs.   For more information on calculating your soundproofing project costs, call NetWell Noise Control at 1-800-638-9355 or complete their Room Analysis Worksheet online!
