Abstract:

The main idea behind development this project is to reduce sound pollution which is generated by Dolby system. In Dolby system, loudspeakers play major role in producing sound pollution. In the field of acoustics, noise investigations involving regulated measurements, this requires sophisticated and expensive equipment and obtaining data sets for subsequent analysis becomes very difficult and complicated. Since functions and parameters can be easily redefined by changes in the programmed instructions. Furthermore, this method avoids a redesign of a physical circuit. In this work, the design and implementation of an android app is presented. The system is implemented with android app and RF communication. The advantage to choose RF communication is that it will control the sound level automatically when the system enters into RF zone.
