Frequently Asked Questions
What are STC ratings and why do they matter?
STC (Sound Transmission Class) measures how well a wall or structure blocks airborne sound. A higher STC rating means better sound isolation. Our STC Ratings Calculator helps you estimate how effective your wall is at blocking sound and whether it meets building code requirements.
How many acoustic panels do I really need?
The number of acoustic panels depends on your room size, surface materials, and intended use (e.g., recording, home theater, or general sound control). Our Acoustic Panels Calculator uses proven formulas to give you exact panel counts and recommended placement areas.
Can these calculators help me reduce outside noise?
Yes. Tools like the Soundproofing Cost Estimator and STC Ratings Calculator are specifically designed to help block or reduce traffic noise, neighbor noise, and urban sound pollution through structural improvements and material upgrades.
Are the tools free to use?
Yes, all of our calculators are completely free and browser-based. There’s no account or login required. You can use them as often as needed for your home, studio, or business.
Are the cost estimates accurate?
Our Soundproofing Cost Estimator uses real-world material pricing ranges to provide budget estimates. While prices may vary slightly by region or supplier, we aim to stay within ±15% of typical market rates. You’ll also get product links to explore actual prices.
Can I use these tools on my phone?
Yes. All our calculators are mobile-friendly, designed to work seamlessly on phones and tablets—whether you’re on a job site, in a showroom, or working from home.
Do you recommend specific products?
Yes. Each tool provides material suggestions with affiliate links to trusted retailers like Amazon or GIK Acoustics. We only recommend products that are widely used in the industry and meet high performance standards for soundproofing and acoustic control.
Do these tools account for impact noise like footsteps?
No. STC measures airborne sound (voices, music, etc.), not impact noise like footsteps or dropped objects. For flooring noise, you’ll need solutions such as underlayment, floating floors, or impact-rated assemblies. We are working on an impact sound calculator for future release.
Can I save or print my results?
Yes. Each calculator includes a save or export function that allows you to download your results as a PDF report. You can also generate shareable links for project collaboration.
