Match your decibel reading to these everyday sounds to see how loud it is and how comfortable it is over time.
| Level | Typical sound | Comfort over time |
|---|---|---|
| 0–20 dB | Breathing, rustling leaves | Comfortable |
| 20–40 dB | Whisper, quiet library | Comfortable |
| 40–55 dB | Quiet office, light rain | Comfortable |
| 55–70 dB | Normal conversation, dishwasher | Comfortable |
| 70–85 dB | City traffic, vacuum cleaner | Tiring over long periods |
| 85–100 dB | Lawn mower, motorcycle, blender | Best limited to ~2 h |
| 100–115 dB | Nightclub, chainsaw, loud concert | Best kept brief |
| 115+ dB | Siren nearby, jet takeoff, fireworks | Very loud — keep brief |
This tool measures estimated noise levels for your home, office, factory, class room, and more. It provides real-time sound level readings in decibels (dB) using your device's microphone. Here are the steps to measure real time noise leve from your laptop or phone:
Your browser will ask for permission the first time. Nothing works until you allow it — and nothing is recorded once you do. If you said no by accident, you'll need to re-allow it in your browser's site settings.
Rest your phone or laptop where you actually want to measure, and try not to tap, breathe on, or shuffle near the mic — it hears all of that. Give it a few seconds to settle into a steady reading.
The big number is the current level in decibels; the colour and the line underneath ("Quiet", "Loud"…) tell you what that means in plain terms. Green is fine, amber is getting tiring, red means protect your ears.
Average, peak, quietest, and time spent above 85 dB fill in as you go — handy for catching that one loud spike you'd otherwise miss. Hit Reset to start a fresh session whenever you like.
A noise meter (also called a sound level meter) measures how loud the sound around you is and reports it in decibels (dB). Professional versions are handheld devices used by audio engineers, safety inspectors, and acousticians. This tool does the same basic job using the microphone already built into your phone or laptop — no extra hardware needed. It listens to the ambient sound, calculates its loudness in real time, and shows you a live reading along with how that level compares to everyday sounds.
Decibels (dB) tell us how loud a sound is. Because the scale is logarithmic rather than linear - each increase reflects a much bigger change in sound intensity than the numbers alone might suggest. For example – a sound at 70 dB is generally perceived as about twice as loud as a sound at 60 dB.
To put common sound levels into perspective, 0 dB is the quietest sound most people can hear. Everyday sounds vary quite a bit in volume. A quiet room is generally around 30 to 40 dB – whereas a normal conversation is about 60 dB. Once sound levels rise above 85 dB – long-time exposure can affect your hearing. Loud noises such as fireworks or a jet taking off often cross 120 dB – and may cause immediate hearing damage.
This tool records the amount of time you spend in environments where noise exceeds 85 dB. Health organisations consider this an important threshold – because prolonged exposure can gradually affect your hearing.
Don't cover the microphone with your hand, a case, or a pocket, and place the device on a stable surface instead of holding it — handling noise and wind can throw off the reading.
Give the meter a few seconds after starting so it can smooth out the initial spike and reflect the actual steady-state level of the room.
Phone and laptop mics vary a lot between devices. If you have access to a certified meter, use the calibration slider to line this one up with it for closer results.
Fans, air conditioning, notifications, and your own breathing near the device can all skew a reading — step back a little for a cleaner measurement of the room itself.
Anywhere sound levels matter for comfort, focus, or safety. A few common places to check:
This online tool provides an estimated noise level of your surroundings for everyday use. It uses microphone of your smart-phone, laptop or desktop. Treat them as a good ballpark, not a lab result. The mic in a phone or laptop isn't a calibrated instrument, so your reading can sit within roughly 10 dB of what a professional meter would show.
Nope, that's normal. Genuinely silent rooms basically don't exist indoors — there's always a fridge humming, traffic bleeding through a window, or the faint hiss of the mic itself. Even a still bedroom at night usually lands somewhere in the 30s or low 40s.
No to both. The sound is turned into a loudness number the instant it reaches the page and then it's gone — nothing is recorded, saved, or sent to a server. It all happens inside your browser, and it stops the moment you press Stop or close the tab.
It nudges every reading up or down so you can line this meter up with one you trust. If you've got a proper sound level meter (or even another app you believe), put them side by side and slide until the numbers match. After that, your readings will be closer to the real thing.
Because real sound never holds still — a passing car, a word spoken, a door closing all move the needle. The meter already smooths things a little so it doesn't flicker wildly, but some movement is the honest picture of what's happening around you. Look at the average if you want one steady figure.
It's the level where long exposure starts to matter, not where anything happens instantly. Roughly speaking, 85 dB is fine for a couple of hours, but every few decibels louder shortens that comfortable window sharply — a loud concert is best kept brief. The fixes are simple: step back from the source, turn it down, or use ear protection. That's exactly why we track your time above 85 dB.
It's a great reality check, but it isn't an official measurement — accurate figures come from a calibrated meter, often taken by someone qualified. Use this to get a rough sense of how loud things really are before deciding what to do next.
Yes, completely free. There's no sign-up, no trial that runs out, and no paid version hiding the useful bits. Measure as often as you like, on as many devices as you like — you won't be asked for a card at any point.
Readings are estimates — phone and laptop microphones are not calibrated instruments and can differ by ±10 dB from a professional meter. Use the calibration slider to match a reference meter if you have one.
