Conditions for using this guide
Use the notebook to understand a problem and prepare better questions—not to replace a project-specific design.
Publisher and scope
This website is published by Feedcometbazar Ltd, 24 Alder Lane, Bristol BS1 4PX, United Kingdom, Company No. 14827635. These conditions explain the basis on which the free information and browser-based tools are provided.
Information, not professional instructions
Articles explain general acoustic principles. They are not architectural, engineering, legal, fire-safety or regulatory advice for a particular building. Concept diagrams omit details required for construction. No article, image or tool output certifies performance or creates a professional-client relationship.
Obtain competent advice before altering structural elements, fire-resisting assemblies, electrical installations, ventilation or services. Confirm applicable regulations, permissions and current standards. Never compromise safety or required ventilation in an attempt to reduce noise.
Evidence and outcomes
We aim to explain terminology accurately but cannot promise that all information is complete, current or suitable for your circumstances. Product performance depends on the tested assembly and installation. Comfort improvements are not the same as measured compliance. We do not guarantee a reduction in noise or a particular acoustic rating.
Local message tool
The contact-page tool formats your own text in your browser. It does not send an enquiry or book a consultation. Review output before sharing it. You are responsible for deciding what to include, where to save a download and who receives any copied text.
Permitted use
You may read, link to and print pages for personal reference. You may use your own generated room notes without restriction from us. Do not misrepresent this website's material as an independent test report, remove context to imply a performance guarantee, misuse the site or interfere with its operation.
Original editorial text and diagrams are protected by applicable intellectual-property law. Third-party materials remain subject to their respective rights. Statutory quotation and other lawful exceptions are unaffected; seek permission for substantial republication.
External references
Links to standards bodies, professional organisations and guidance provide context. They do not imply affiliation, approval or endorsement. External sites have their own content, conditions and privacy practices.
Liability and statutory rights
To the extent permitted by law, we are not responsible for losses caused by treating general information as a site-specific specification or for interruptions outside our reasonable control. Nothing in these conditions excludes liability for fraud, fraudulent misrepresentation, death or personal injury caused by negligence, or any other liability that cannot lawfully be excluded. Your mandatory statutory rights are unaffected.
Changes and questions
Content and these conditions may change as the notebook develops. The current conditions appear on this page. English law applies, subject to any mandatory protections and jurisdiction rights available to you where you live. For questions or corrections, contact us.
