Sound Meter is in the 4th set of the Smart Tools collection.
Have you ever suffered from the noise of the neighbors?
SPL(sound pressure level) meter app uses your embedded microphone to measure noise volume in decibels(db), and shows a reference.
Covid-19 forced many to stay at home and forced many to listen to noisy neighbours too. However, how noisy is noisy? One way to find out is to measure it and then you got the solid evidence.
This professional-grade sound level meter is measured after a traditional sound press level (SPL) meter, including ballistics, ranges, filters and decay rates. It uses your device’s microphone to detect sound and convert it into a SPL value. The app comes pre-calibrated for most mobile devices but can be adjusted to match professional calibrated meters. The universal app can be shared on all devices. A simple color-coded display indicates safe (green) and dangerous (red) hearing levels.
