3. Informational Nature of Educational Tools & Calculators

The interactive utilities made available on this website—including but not limited to the Sabine RT60 Reverberation Estimator, the Uncompressed PCM Bitrate Calculator, and acoustic absorption tables—are provided strictly for preliminary research, pedagogical exploration, and conceptual engineering evaluation.

Important Engineering Disclaimer: Online mathematical models assume idealized diffuse sound fields and uniform absorption distributions. Real-world architectural acoustics are governed by low-frequency modal resonance, structural flanking transmission, HVAC noise criteria, and construction tolerances. The output of our calculators does not constitute a substitute for certified physical on-site measurement or stamped structural acoustic design.

4. Intellectual Property & Permitted Usage

All proprietary source code, algorithmic scripts, visual waveforms, technical illustrations, research whitepapers, diagrams, and brand elements displayed on this platform are the exclusive intellectual property of Cerri Lisa and are protected under the French Intellectual Property Code (Code de la propriété intellectuelle) and international copyright conventions.

A. Permitted Use

You are granted a revocable, non-exclusive, non-transferable license to access the platform for individual educational study, non-commercial acoustic research, and preliminary studio planning.

B. Prohibited Actions

  • Scraping, crawling, harvesting, or extracting data via automated scripts or AI training bots without explicit written authorization;
  • Decompiling, reverse-engineering, or mirroring the calculation engine or visual spectrum canvas;
  • Republication or commercial redistribution of our technical whitepapers or diagrams without proper academic citation and prior permission;
  • Bypassing or attempting to disable any security features, HTTP headers, or rate limits.

5. Professional Consulting & Engineering Engagements

Submission of a consultation inquiry via our online contact forms does not establish a formal client-consultant contract until:

  1. A formal scope of work, technical specification dossier, or commercial proposal has been issued by Cerri Lisa;
  2. Mutual agreement on milestones, fees, and deliverables has been established in writing; and
  3. Any required initial engagement deposit has been settled.

6. Limitation of Liability

To the maximum extent permitted under applicable French and European law:

  • The platform and all included materials are provided on an “AS IS” and “AS AVAILABLE” basis without warranties of any kind, whether express or implied;
  • Cerri Lisa disclaims all liability for direct, indirect, incidental, consequential, or punitive damages arising from the implementation of acoustic estimates, construction decisions based on preliminary calculators, or temporary site downtime;
  • Nothing in these Terms limits liability for gross negligence (faute lourde), willful misconduct (dol), or physical injury where prohibited by mandatory French law.

7. Hyperlinks to Third-Party Resources

Our whitepapers and guides may contain hyperlinks to external regulatory frameworks (such as ITU-R, EBU, AES, ISO, or CNIL). Cerri Lisa exercises no control over external third-party servers and accepts no responsibility for their content, availability, or data privacy practices.

8. Governing Law and Dispute Resolution

These Terms shall be governed by, construed, and enforced in accordance with the laws of the Republic of France.

In the event of any dispute, claim, or controversy arising out of or relating to these Terms or the use of the platform, the parties shall first endeavor to resolve the matter amicably through good-faith technical discussions. Should amicable resolution fail, any legal proceedings shall be submitted to the exclusive jurisdiction of the competent courts within the judicial district of the Court of Appeal of Montpellier, specifically the Tribunal de Commerce de Perpignan (France).
