What matters the most in educational institutions is the effectiveness of communication between the students and the teachers. Studies demonstrate that classroom acoustics influences the clarity of communication between students and teachers, which eventually impacts the process of learning and knowledge acquisition. Disturbances in the form of sound from classrooms nearby would hamper the knowledge transfer from teachers and the receptiveness of students to a great extent. Gypsum plastering provides sound insulation between classrooms on the campus and thus enables a seamless transfer of knowledge.
