Decibel Meter - Measure noise levels instantly - no app needed

👋 Hey Product Hunt community! I'm thrilled to share Decibel Meter with you today—a completely free, browser-based sound level meter that works instantly on any device. 🎯 The Problem We Solved: Most sound measurement apps require installation, cost money, or raise privacy concerns. Meanwhile, certified decibel meters cost hundreds of dollars. We wanted to create something that's accessible to everyone while maintaining professional-grade features. ✨ What Makes Us Different: Zero friction: Open the website, allow microphone access, start measuring Privacy-first: All audio processing happens locally in your browser—we never record or transmit your audio Educational: Real-time comparisons, health impact warnings, and safe exposure time calculations Universal: Works on desktop and mobile, iOS and Android, any modern browser 🎧 Use Cases We've Seen: Parents checking if their baby's room is quiet enough Remote workers monitoring home office noise Educators teaching students about sound science Musicians checking venue sound levels Safety managers doing quick workplace assessments ⚠️ Honest Disclaimer: We're transparent that this is for reference use. Device microphones vary in quality, so we recommend certified equipment for professional/legal purposes. But for everyday awareness? We've got you covered. 🙏 Would Love Your Feedback: What features would make this more useful for you? Any use cases we haven't thought of? What would you add to make it even better? Thanks for checking us out! Happy to answer any questions about the tech, accuracy, or future plans. 📊🔊
