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.
🔹 Main Features
Real-time noise measurement with display in decibels (dB)
Visualization of sound level: numeric values and a dynamic indicator
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
Supporting educational projects and experiments
Evaluating volume of music, TV, speakers, or headphones
🔹 App Features
Adapted accuracy based on the microphone of your smartphone
Option to save and review measurement results
Clean, minimalistic design without unnecessary elements
Lightweight app that does not overload your device
🔹 Who Can Benefit
Users concerned about protecting their hearing
Parents checking safe volume levels for children
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.

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.
