About this app
Turn your phone into a dB decibel meter and measure sound and noise levels in seconds. Just open the noise meter app to get live readings and instantly see the noise level around you. No need for expensive sound level meters when the tool you need is already in your pocket. Neighbors too loud, want to measure noise at work or check the sound volume at a concert? This sound decibel meter gives you real numbers instead of a guess.
Real-Time dB Readings
The noise meter measures sound as it happens and shows your current, minimum, average and maximum levels at a glance, along with a live chart of how the noise changes over time. Unlike a basic decibel reader, it explains every reading with a real-world comparison, such as falling leaves or a quiet library, so you always know what the number means. If the noise gets too loud, a warning appears right away.
Record Noise on Video
Switch to the camera to record videos or take photos with the sound meter reading shown right on the screen: current dB, minimum, average and maximum values, a sound wave and a timestamp. It's the easiest way to document a noisy neighbor, a construction site or street traffic and show exactly how loud it was.
Add Notes to Every Recording
Mark key moments while you measure. Add a short note and the sound meter will save it with the exact time and dB value, so you always remember what caused each spike.
Precise Calibration
Every phone microphone is a little different. Use the calibration tool to add or subtract a few dB and match your readings to a professional sound level meter. A few seconds of fine-tuning makes this dB meter much more accurate.
Noise Logs in One Place
Save every sound measurement and find it later in your history. Each log shows the date, start time, duration, minimum, average and maximum dB, plus a short description of the noise level. Our sound meter is an ideal tool when you need a noise level meter for an ongoing problem like a noisy neighbor.
Easy Sharing
Share any recording in seconds with your landlord, employer, building manager or a friend. Your sound measurement data is always ready when you need proof.
dB Alerts
Set your own warning level and get notified as soon as the noise goes over your limit, so the sound meter keeps watch for you. You can also keep the screen on during long sessions, save audio files and open records right after saving.
One App, Many Tools
This noise meter combines a dB meter, noise level meter, volume meter and SPL meter in one simple app. Whether you need a quick dBA detector for everyday checks, a handy decibel reader or a sound level meter that fits in your pocket, you always have it with you.
Where to Use Your Sound Decibel Meter
• Home: check noisy neighbors, appliances or a baby's room
• Work: measure office, factory or workshop noise
• Study: keep a classroom or library quiet
• Music: use it as a volume meter to see how loud a concert, rehearsal or speaker really is
• Outdoors: test traffic, construction and street noise with a portable noise level meter
• Health: take quick sound measurements to spot volume levels that may harm your hearing
Good to Know
Phone microphones aren't certified lab equipment, so treat this sound decibel meter as a reliable reference tool rather than an official SPL meter or dBA detector. For the most accurate results, calibrate it against a known sound level meter.
