Sound filed amplification has been used effectively to enhance listening and learning environments since the earlier 1980s. The primary goals of soundfield amplification are to: 1) improve the signal-to-noise ratio in the classroom, and 2) provide uniform amplification throughout the classroom. The efficacy of sound-field classroom amplification has been documented through research studies, with the 3-year Mainstream Amplification Resource Room Study (MARRS) being the first study reported in the literature in 1981. The following is a retrospective summary of research on the application and documented finding so sound field amplification for both students and teachers.
