[{"data":1,"prerenderedAt":-1},["ShallowReactive",2],{"content-seo:soundMeter":3},{"description":4,"seo":5,"faq":8},"A free online decibel meter that turns your phone or laptop into a quick sound level meter — no app, no install. Allow microphone access and the noise level around you shows in decibels (dB) live, with the minimum, average and maximum since you started plus a rolling graph of the last few seconds. Use it to check whether a bedroom is quiet enough to sleep, how loud an open-plan office or café gets, or how much a fan or street adds. A calibration slider (±15 dB) lets you match a real meter. Readings are estimates (±5–10 dB) and not A-weighted, so it is not a certified sound level meter. Sound is analysed on your device only and never recorded or sent.",{"ogTitle":6,"ogDescription":7},"Decibel Meter Online | Free Sound Level Meter (dB) - Giggleus","🔊 Check noise levels in dB with your phone or laptop mic — live reading plus min, average and max. Free, no app, nothing recorded.",[9,12,15,18,21],{"question":10,"answer":11},"How do I measure decibels with my phone?","Open this page, press Start measuring and allow microphone access; the current dB level updates live and the minimum, average and maximum are tracked from that moment. Keep the mic uncovered and measure for 30 seconds or more for a representative average.",{"question":13,"answer":14},"How accurate is a phone decibel meter?","Expect an estimate within roughly ±5–10 dB, and more without calibration. Phone mics differ in sensitivity, readings here are not A-weighted, deep bass thuds are under-picked and very loud sounds can read low once the mic saturates; matching a real meter with the calibration slider narrows the gap.",{"question":16,"answer":17},"How loud is 30, 60 or 90 dB?","Roughly: 30 dB is a whisper, 40 dB a library or quiet bedroom, 60 dB normal conversation, 70–85 dB heavy traffic or a vacuum cleaner, 80–90 dB a subway train, 100 dB or more a concert or club, and about 120 dB a siren up close. Every 10 dB increase sounds about twice as loud.",{"question":19,"answer":20},"What decibel level damages hearing?","Risk starts with long exposure at about 85 dB: occupational guidelines such as NIOSH set 85 dBA as the limit for 8 hours a day, and every 3 dB more halves the safe time, to about 1 hour at 94 dB and 15 minutes at 100 dB. If your ears ring or sound muffled after noise, see a doctor.",{"question":22,"answer":23},"Can I use this as evidence in a noise complaint?","No. Official noise measurements for neighbor disputes, workplaces or environmental limits use certified Class 1 or Class 2 sound level meters (IEC 61672) with A-weighting and set procedures. Use this tool to gauge the problem, then ask your local authority about an official measurement."]
