Sound Meter Pro Noise Detector

Sound Meter Pro is a tool for measuring noise and sound levels using the built-in microphone of your smartphone. The app turns your phone into a decibel meter, allowing you to check sound intensity in decibels (dB) and monitor the acoustic environment around you.

Noise is a part of everyday life: traffic, construction, loud music, household appliances. Excessive sound can interfere with work, rest, and may affect health. With Sound Meter Pro, you can measure noise levels in real time and take steps to reduce unwanted impact.

Graph of sound changes for better analysis

Saving measurement history with access to previous results

Simple interface that is easy to use

Multi-language support through built-in localization

🔹 Use Cases

Measuring noise at home (neighbors, appliances, music)

Checking office sound levels for a comfortable workspace

Monitoring classroom or lecture hall acoustics

Testing sound insulation of windows, doors, or walls

Students and teachers using it in education

Professionals in sound and acoustics who need a portable tool

Anyone who wants to better understand the noise level in their environment

Important Note
Accuracy depends on the characteristics of your device’s microphone. Results may vary across different smartphone models. However, for everyday use, Sound Meter Pro helps track noise levels and monitor sound conditions effectively.

Recent changes:
Added:
1. A/C/Z weighting support. Professional sound level meters measure dBA (human hearing perception), not just raw dB. The app now supports proper frequency weighting for more accurate noise measurement.
2. LAeq — equivalent continuous sound level. International standards such as WHO and OSHA use LAeq to evaluate noise exposure over time. The app now calculates the integrated sound level for a selected period.
