Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Drywall area = net wall area × finished sides × layers. Channel rows derive from wall height and spacing. Sealant models perimeter and sheet seams.

FAQ
Drywall Soundproofing Calculator questions
Does adding more drywall always improve sound control?+
Additional mass can help, but decoupling, cavity absorption, airtightness and flanking paths are also important.
Are resilient channel and isolation clips interchangeable?+
No. They are different systems with different layouts and tested assemblies.
Why is acoustic sealant included?+
Air gaps and unsealed edges can significantly reduce the performance of an otherwise well-built assembly.
