Decibel Meter Noise Around

Real-time noise monitoring
Large analog dial and digital readout show the current sound level in dB from 0 to 140.

Min / Avg / Max tracking
The app continuously tracks minimum, average and maximum noise levels for your session.

Context hints for every reading
Under the gauge you see a quick hint like
“70 dB – Busy restaurant / loud office”
so you immediately understand what the current level means.

Full dB reference chart
Expand the list to see a detailed chart from 10 dB to 140 dB with real-world examples:
breathing, quiet room, whisper, quiet office, conversation, busy traffic, subway, rock concert, jet takeoff, gunshot, and more.

Color-coded level bar
A horizontal bar from blue to yellow to orange shows how close you are to dangerous levels at a glance.

Per-device Sensitivity Calibration
Microphone sensitivity depends on your phone.
Use the calibration card to fine-tune the reading: reset, then adjust the offset with – / + buttons (e.g. 78 + 0 dB).

Professional weighting filters
Choose how the meter processes sound:

dB A-weighting – Recommended
Closest to human hearing, use this for everyday noise.


dB C-weighting – for very loud environments and peak levels.


Linear – no filtering, for technical/raw measurements.
