Terms of Service - Usage Guidelines & Disclaimers
Last Updated:
This free online decibel meter is provided for educational and personal use. By using this tool, you agree to these terms. Not suitable for professional certification or legal compliance measurements.
Acceptable Use
This tool is designed for general noise monitoring—checking room noise, measuring appliance sounds, teaching about acoustics, or satisfying curiosity about your environment. Use it for personal, educational, or non-commercial purposes. Don't use it to harass others or invade privacy.
Accuracy Disclaimer
The tool starts immediately with an estimated sound-level display derived from a generic microphone mapping. Optional comparison with a physical reference meter applies one device-specific adjustment. Both states remain unweighted browser estimates: they are not dBA or dBC measurements, traceably calibrated, or certified.
Not for Professional Certification
This tool is NOT suitable for OSHA compliance, legal documentation, workplace safety certification, building code enforcement, or any purpose requiring certified equipment. For professional applications, use a calibrated Class 1 or Class 2 sound level meter. Our readings are for reference only.

The site always loads GA4 and self-hosted Umami analytics as disclosed in the Privacy Policy. The Google AdSense page script is currently paused while ownership verification remains. Applicable consent controls and the Privacy Policy govern Google services. Do not manipulate ads, clicks, impressions, consent signals or analytics.
Changes to Terms
The service is provided as-is without warranties. We are not liable for hearing injury, workplace exposure, legal evidence, equipment damage, or decisions based on these estimates. Follow authoritative guidance and seek qualified help where needed.
Updates and Contact
We may update these terms and will publish a fixed revision date. Questions, correction requests, or legal notices can be sent to [email protected]. Microphone permission can be revoked at any time in browser settings.
