A Smart Sound Tracking Device
In this we propose a system for reliable detection of the direction of the audio source. Compared with previous researches, the system comprises simpler, faster and more accurate algorithm and a threshold level setting mode to make the system immune to external noise. The main objective of this project is to detect the sound source, track the direction of audio source and move in that direction. The sound source is detected using microphones. The microphones sense the sounds up to a pre-defined threshold level. Now, the received signal strengths are compared and the device moves towards the direction of maximum signal strength obtained. This operation is controlled by using a microcontroller. The next step is to move the device in the maximum signal strength direction. Motors are used in order to move the device in the desired direction. This can be used in security purpose for detecting un-authorized persons.
