Sound Meter is a mobile application that measures the sound pressure level (SPL) in decibels (dB) using the embedded microphone of your smartphone. The app is part of the Smart Tools collection and is designed to help users determine the noise volume in their surroundings. The app provides a reference for the noise level and can be used to check if the noise level is too high or too low. However, it is important to note that most smartphone microphones are aligned to human voice and have a limited maximum value, which means that very loud sounds may not be recognized.

The app is a useful tool for anyone who wants to measure the noise level in their surroundings. It can be used to check if the noise level is too high or too low, and can be used to determine if the TV volume or the voice in a lecture is too loud. The app is easy to use and provides accurate results in routine-noise levels (40-70dB). However, it is important to note that the app should be used as an auxiliary tool and not as a replacement for a professional sound meter.

The app has several features, including upside-down mode, level notification, line-chart duration, and material design. The pro version of the app includes additional features such as no ads, vibrometer, statistic menu, and CSV file exporting. The app is available for download on the Google Play Store, and users can also download the Smart Meter Pro and Smart Tools package for more tools. For more information about the app, users can watch YouTube videos and visit the blog.
