Using the toolkit.
You may use the tools for lawful planning without an account or fee. Outputs are estimates and general guidance, not professional measurements, building designs, warranties or guaranteed reductions. Using or downloading a result creates no acoustic consultant, contractor, healthcare, legal or financial-adviser relationship. If these limitations are not acceptable, do not rely on the tools.
Your assumptions and decisions.
Use accurate, consistent units and non-identifying details. Read the visible method and check outputs before making spending, construction or household decisions. The noise estimator is an educational scenario using explicit example allowances, not verified construction performance. You remain responsible for professional review, permissions and real-world agreements.
Building and household safety.
Keep ventilation, alarms and escape routes functional. Do not block necessary openings, disable warnings or change fire doors, building services, structure or electrical elements on the strength of a worksheet. Hazardous materials and installation risks require suitable qualified assessment. A quiet-feeling room is not a safety certification.
No measurement, price feed or guarantee.
The tools do not measure real decibels, fetch live prices or guarantee a specific noise reduction. They do not book services, approve construction, verify product claims or determine legal compliance. Cost defaults and material descriptions are illustrative or generic, not binding offers or recommendations to purchase.
Bedroom and health limits.
The bedroom planner provides clock arithmetic and environmental prompts, not a sleep test or treatment. Time in bed is not measured sleep. Do not use the output to diagnose a condition or delay appropriate care for persistent sleep difficulties or health concerns.
Permitted use and licence.
You may download or print your own results and share non-identifying notes. Do not disrupt the site, probe other users’ information, introduce malicious code, impersonate the operator or misrepresent a worksheet as professional evidence. The supplied plugin code is licensed GPL-2.0-or-later; rights under that licence and applicable law remain intact.
Availability, errors and rights.
The service may change or become unavailable and simplified outputs may be unsuitable or contain errors. To the extent permitted by law, no promise is made of uninterrupted availability or fitness for every home. Nothing here removes mandatory consumer rights or liabilities that cannot lawfully be excluded. No governing jurisdiction or professional credential is invented.
Questions and changes.
Stop relying on a result you cannot explain. Contact the operator with a reproducible invented example for a website issue; obtain appropriate professional advice independently. Linked external resources control their own services and terms. The operator should review these conditions for its actual installation and update them as needed.
