I built SoundLevelMeter.org because checking noise levels shouldn’t require downloading heavy apps or buying special hardware. Open the site, grant microphone access, and you’ll see real-time dB readings right in your browser. Key Features 🌐 Works Anywhere – Runs in any modern browser on desktop or mobile. 📊 Real-time Graphs – Instant decibel display with a smooth, responsive chart. ⚙️ No Setup – No downloads, no account. Just click and measure. 💡 Useful Everywhere – Test office noise, monitor home studio levels, or check if a café is too loud. Why I made it As a developer and chef (lots of kitchen clatter!), I wanted a quick way to check if environments were safe for my son and family without juggling extra apps. 👉 Try it now: https://soundlevelmeter.org
