Informational use only

All content is published for general information about acoustics and building practices. It is not professional, engineering, or legal advice, and it does not establish any professional relationship. Decisions about construction, renovation, or code compliance should be confirmed with a qualified professional and the relevant authority.

No warranty

Acceptable use

You agree not to misuse the site, attempt to disrupt its operation, or use the content in a way that misrepresents it as professional certification or advice.
