About this app

Turn your phone into a handy noise meter with Decibel Meter — the simple, accurate way to measure the sound around you in decibels (dB). Using your device's microphone and a smart, energy-efficient algorithm, it shows real-time noise levels wherever you are, from a quiet library to a roaring concert.

We live in a noisy world, and too much of it can harm your hearing. Decibel Meter helps you become aware of the sound levels you're exposed to, so you can protect your ears and your peace of mind. See live readings plus the minimum, average and maximum levels for a full picture of your environment.

UNDERSTAND THE NOISE AROUND YOU

From the hush of a whisper to the blast of a jet engine, sound covers a huge range — and the app helps you make sense of it. A built-in reference guide shows what typical decibel levels feel like, so you instantly understand whether your surroundings are calm, loud or potentially harmful.

PROTECT YOUR HEARING

Long exposure to loud noise can cause permanent damage you can't undo. By checking the decibels at concerts, worksites, gyms or busy streets, you can decide when to step back, turn it down or reach for ear protection. Awareness is the first line of defense for healthy hearing.

EVERYDAY USES

• Check noise at home, work, school or the gym.
• Measure how loud a room, appliance or event really is.
• Settle "is it too loud in here?" debates with a number.
• Stay mindful of your daily sound exposure.

HOW IT WORKS

1. Open the app and let it read the ambient sound.
2. Watch the live decibel level rise and fall.
3. Note the min, average and max — then copy if you like.

PERFECT FOR

• Anyone curious about the noise in their environment.
• Protecting hearing at loud events and workplaces.
• Parents, teachers and considerate neighbors.
• Quick, everyday sound checks on the go.

Please note: most device microphones are tuned for voices and have hardware limits, so very loud sounds (above ~90 dB) may not be captured precisely. For professional-grade readings, use a dedicated sound level meter — but for everyday awareness, Decibel Meter is the perfect pocket companion.

A NOISE METER YOU'LL ACTUALLY USE

There's no setup and no clutter — open the app and you're instantly measuring. The big, clear readout is easy to read across a room or at a glance, and capturing the minimum, average and maximum gives you the whole story, not just a single moment. It's noise measurement made genuinely simple.

KNOW YOUR ENVIRONMENT

Curious how loud your office, gym, classroom or street really is? Whether you're a concerned parent, a thoughtful neighbor, a musician or just naturally curious, Decibel Meter helps you put a real number on the noise in your daily life.
