Decibel meter-Sound Noise test is a utility application for Android that functions as an intelligent sound level meter. This app allows users to measure and monitor ambient noise levels, helping to prevent noise pollution that can harm hearing. It displays sound levels in decibels (dB) and features real-time measurement capabilities, making it a practical tool for sound testing in various environments.

Key features include real-time chart updates, the ability to display decibel measurement over time, and play/pause functionality for sound tests. While the app provides a convenient way to gauge noise levels, users should note that its accuracy may not match that of professional sound pressure level meters. It is recommended to calibrate the app in a quiet environment or with an actual SPL meter for best results.
