Description
Turn your smartphone into a portable and accurate environmental noise measurement tool.
Sound Level Meter (also known as a Decibel Meter, Noise Meter, or SPL Meter) uses your device’s built-in microphone to measure sound pressure levels in the surrounding area. It provides instant readings in decibels (dB) displayed on a clear, professional interface.
Whether you are checking noise pollution in your neighborhood, testing audio equipment setups, or just curious about the volume of your environment, this app offers a simple yet powerful alternative to expensive physical instruments for everyday measurements.
KEY FEATURES: 🔊 Real-Time Decibel Reading Get instant visual feedback on current noise levels. The app features a highly readable analog-style gauge alongside a precise digital display, making it easy to read fluctuating sound levels at a glance.
📈 Live Data Graphing Visualize sound changes over time. The dynamic line chart at the bottom of the screen helps you identify noise trends, spot intermittent volume spikes, and monitor environmental stability over a period of measurement.
🔢 Min / Avg / Max Statistics Don't just see the current level; get the whole picture. The app automatically tracks and displays the Minimum, Average, and Maximum decibel values recorded during your session.
⚙️ Measurement Calibration While most devices are reasonably accurate out of the box, microphone sensitivities vary. Our app includes a calibration feature, allowing you to adjust the decibel offset to match professional tools or normalize readings across different devices for enhanced precision.
📱 Clean & Professional Interface Designed with a modern dark theme that is easy on the eyes and intuitive to navigate, allowing you to focus on the measurements.
COMMON USE CASES: Measuring environmental noise pollution (traffic, construction, etc.).
Checking sound levels in classrooms, offices, or at home.
Testing home theater or car audio system output.
Ensuring venue noise levels are within comfortable limits.
IMPORTANT NOTE ON ACCURACY: Please be aware that the microphones in most Android smartphones are aligned to human voice frequencies. Therefore, very loud sounds (often above 90dB) or very low-frequency sounds may not be recognized as accurately as a specialized hardware SPL meter. For critical professional measurements, please use a calibrated instrument.

Fantastic application! Considering that it is free I love it.
★★☆☆☆Edmund Stokes-Waller· Mar 5, 2019
Does not work on samsung A3. Developer contacted which I view as positive. Perhaps related to multiple apps loaded on phone. Noticed with other apps that some does not work when other apps open (although this is not the case here, checked all options, also restarted phone and this app still does not function). Other sound level apps work (or majority at least on phone).
