The app is a smart platform for monitoring noise pollution in public spaces using smartphones. It utilizes the phone's microphone to measure noise levels in decibels (dB) in real time, along with GPS location, without recording any audio to protect privacy. Measurement data is sent to a central database, where it is processed using data analysis algorithms to filter out inaccurate values. The results are then displayed on an interactive heat map showing noise levels by location and time. The app allows users to view the average noise level, the highest and lowest values, and analyze time periods.
