Terms and Conditions

Last updated: June 2026

These Terms and Conditions govern your access to and use of Reverb-Calculator.com and all tools, articles, and content provided on this website. Reverb-Calculator.com is operated by Noah Bennett (contact available via the Contact page).

By accessing or using Reverb-Calculator.com, you agree to these Terms and Conditions in full. If you do not agree, please discontinue use of the website.

1. Purpose of the Website

Reverb-Calculator.com is an independent educational website providing free browser-based RT60 reverberation time calculation tools and educational content about room acoustics, acoustic formulas, absorption coefficients, and room design targets.

The website is intended for educational use, general acoustic planning reference, and exploration of room acoustic principles. It is not designed to replace professional acoustic engineering services, certified acoustic measurement, or formal acoustic specifications.

More information about the site’s purpose is on the About page.

2. Use of the Calculation Tools

The RT60 calculation tools — using the Sabine and Eyring formulas — compute reverberation time from room dimensions and absorption coefficient values you enter. These tools require no microphone access, capture no audio, and do not interact with any device sensor or input beyond receiving the numeric values you type.

By using these tools, you acknowledge that:

Outputs are mathematically exact calculations derived from the Sabine or Eyring formula as applied to your input values
The Sabine and Eyring formulas are models based on simplifying assumptions — diffuse sound field, uniform absorption distribution, and standard room geometry — and real rooms may deviate from these assumptions
The Sabine formula may overestimate RT60 for rooms with high average absorption (mean coefficient above approximately 0.30); the Eyring formula is more appropriate for such rooms
Calculated RT60 estimates are not equivalent to measured RT60 values obtained through professional acoustic measurement per ISO 3382
Results are provided for general educational and planning reference only and are not appropriate for formal acoustic certification, legal specifications, or construction contracts requiring certified acoustic performance

3. No Professional Advice

Reverb-Calculator.com does not provide:

Professional acoustic engineering or consulting services
Certified acoustic measurements or compliance verification
Architectural or construction specifications
Material procurement, installation, or treatment design services

All educational content on this site is provided for general informational purposes. For professional acoustic design, certification, or compliance purposes, consult a qualified acoustic engineer or consultant.

4. Acceptable Use

By using Reverb-Calculator.com, you agree not to:

Use the website for unlawful purposes
Attempt to disrupt, interfere with, or compromise website functionality or security
Use automated tools or scripts to access or interact with the site at scale
Reproduce or redistribute site content for commercial purposes without written permission
Present calculated RT60 estimates from this site as certified or professionally measured acoustic values

5. Intellectual Property

All original content on Reverb-Calculator.com — including written articles, tool interfaces, educational text, RT60 target tables, absorption coefficient reference data, graphics, design elements, and code — is the intellectual property of Noah Bennett and Reverb-Calculator.com unless otherwise stated, and is protected by applicable copyright and intellectual property laws.

6. Privacy and Cookies

Your use of the website is also governed by our Privacy Policy and Cookie Policy, which explain how calculation inputs and cookies are handled on this site.

7. Limitation of Liability

Reverb-Calculator.com is provided on an “as is” basis. To the fullest extent permitted by applicable law, Noah Bennett and Reverb-Calculator.com are not liable for:

Acoustic treatment or construction decisions made based on calculated RT60 estimates
Discrepancies between calculated and measured RT60 values in real rooms
Costs arising from acoustic treatment, construction, or material decisions based on tool results
Decisions made based on absorption coefficient data or room design target information
Technical failures, downtime, or performance issues
Any direct, indirect, incidental, or consequential damages arising from use of this website

Use of the website is entirely at your own discretion and risk.

8. External Links

Reverb-Calculator.com may contain links to external resources — including acoustic standards references, published research, and educational resources. We are not responsible for the content, accuracy, availability, or privacy practices of external websites.

9. Governing Law

These Terms and Conditions are governed by applicable law. Any disputes arising from use of this website will be subject to the jurisdiction of the courts applicable to the operator’s location.
