Sound Meter
Free online decibel meter | real-time noise level detection
Sound Meter launched on December 22, 2025.
What it does
Free online sound meter to measure environmental noise levels in decibels (dB). Real-time sound level meter for detecting quiet, noisy, or harmful sound levels.
Real-time environmental noise level detection using your microphone. Pro Tip: For accurate environmental analysis, measure for at least 30-60 seconds to smooth out sudden noises. Note: Reference-only estimate. Device microphones vary, so results may be shifted. Use Align reading if the baseline looks off. Quiet room ≈ 30–40 dB, conversation ≈ 60 dB, traffic ≈ 80 dB. Note: Decibel scale is logarithmic - each 10 dB increase means ~10x intensity increase. This table is a quick screening view of how daily noise dose changes with level. It uses the NIOSH 3 dB exchange rate approach and is intended for awareness and repeatable comparisons, not compliance measurements. Source: NIOSH/CDC . Estimate…from realtimesoundmeter.org

The tool uses your device's microphone to measure sound from 30-130 dB, with A-weighting to match human hearing perception. It works on both desktop and mobile browsers. Key features: - No installation required - runs entirely in the browser - A-weighted measurements (standard for noise exposure) - Educational content about sound levels and hearing protection - Reference guide for common sound levels - Privacy-focused: all processing is done locally, no audio is recorded…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
