sound-decibelmeter.online is a free, browser-based sound level meter that allows users to measure noise levels in real time using their device’s microphone. Our goal is to provide a simple, accurate, and accessible tool for anyone who needs to check the loudness of their environment—without the need for downloads, installations, or expensive sound equipment.

Whether you're a teacher monitoring classroom noise, a musician testing volume levels, or simply curious about the sound around you, our tool offers a quick and easy solution. We believe that sound awareness plays a vital role in protecting hearing health, improving workspaces, and maintaining a comfortable living environment. That’s why we’ve made this tool available for everyone—no registration or login required.

All audio processing happens locally within your browser. This means we never record, store, or transmit your microphone data. Your privacy is our top priority. The meter operates using your browser’s Web Audio API, which allows sound levels to be calculated in real time based on microphone input—without compromising your personal data.

Our team is passionate about web technology and user experience. We continuously work on improving the accuracy, responsiveness, and compatibility of our tool across devices and browsers. From students and educators to hobbyists and professionals, we aim to serve a wide range of users with a tool that’s intuitive and reliable.

We also provide educational information on decibel ranges and common sound levels to help users understand what the measurements mean. This makes sound-decibelmeter.online a useful reference for sound safety and awareness.
