About Sound Meter Pro
Sound Meter Pro is the 4th set of Smart Tools® collection. ★★ The advanced version (Smart Meter Pro) was newly released. This app (Sound Meter Pro) will continue to be updated, but we strongly recommend that new users purchase the new version. ★★ SPL(sound pressure level) meter app uses your microphone to measure noise volume in decibels(db), and shows a reference. We calibrated a lot of android devices using an actual sound meter with dB(A). REMEMBER!! Most smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore maximum value is LIMITED by manufacturers, and very loud sound(100+ dB) cannot be recognized. Moto G4 (max.94), Galaxy S6 (85dB), Nexus 5 (82dB)... You can trust the result in routine-noise levels (40-70dB). Please use it as an auxiliary tool. Vibrometer uses the phone sensors to measure vibration or an earthquake, and it shows a reference as a seism detector. The measured values are related to Modified Mercalli Intensity scale (MMI). If it is inaccurate, you can calibrate it so that maximum value is about 10-11. Please use the results only for reference because android devices have a wide variety of performance and sensitivity. * Pro version added Features: - No ads - Sound Meter and Vibrometer are integrated - Statistic menu (line chart) - CSV file exporting - Line-chart duration - More models are calibrated For more information, watch YouTube and visit the blog. Thank you. * It is a one-time payment. The app price is charged only once. ** No internet support : You can open this app without any connection. After installation, open the app 1-2 times with your device connect to WI-FI or 3G/4G.
What Sound Meter Pro Is Used For
Sound Meter Pro appears to be a utility app for measuring noise levels with the phone’s microphone and checking vibration with the device sensors. Based on the metadata, it is commonly used as a quick reference tool for estimating sound pressure levels in decibels, especially for everyday noise checks where approximate readings are useful. The app also includes a vibrometer mode, which may help users observe movement or vibration and compare it with a reference scale.
Because it requests microphone access, the app needs that permission to capture audio for sound measurement. The description also mentions exporting CSV data and viewing statistics, so it may be used by people who want to record readings over time rather than just see a single number. It is a phone app, so it is likely most practical for handheld use in homes, workplaces, classrooms, or other routine environments where a portable measurement tool is needed. The metadata notes that results are best treated as reference values, since phone microphones and sensors can vary by device.
Common uses
- Measure ambient noise in decibels using the microphone
- Check whether a room or area is relatively quiet or noisy
- Use vibrometer mode to observe vibration or movement
- Review charts or statistics for repeated readings
- Export measurement data as CSV for later review
- Compare readings against the app’s reference scale
- Use as a portable, on-device reference tool without internet
