The Noise Pollution Monitoring App is a simple mobile application developed using MIT App Inventor to measure and monitor environmental noise levels. The app uses the smartphone’s microphone sensor to detect sound intensity and displays the noise level in a readable format.
It helps users identify high-noise areas and understand the impact of noise pollution on health and the environment. The app is easy to use, educational, and suitable for students and beginners learning sensor-based mobile app development
Set Label.Text to SoundLevel
Displays the current noise level on the screen.
if SoundLevel > Threshold
Checks whether the noise level exceeds a safe limit.
Notifier.Alert Block
Shows a warning message when noise pollution is too high.
Button.Start.Click Block
