Design and Implementation of an Adaptive and Effective Audio System for Classroom

Audio system for a classroom is one of the most important parts of effective teaching and learning process in modern ages due to indoor and outdoor noise level and articulation loss of delivered speeches at distant students. The knowledge of sound engineering is essential for designing an audio system for classrooms at all levels of education. In this paper, we have discussed a novel customized exploded cluster of speakers along with automatic volume control upon detection of students seated at individual coverage areas of each speaker. We have considered all the factors of the room along with a real-time calculation of all the equations set by sound engineers and found the values satisfactory with allowed levels prescribed by world health organization. Finally, we have implemented our proposed cluster of sound system and got expected outcomes, which can be undoubtedly installed for any classroom for healthy and comfortable sound for each student in the class.
