Improving the Classroom Environment: Classroom Amplification Systems. Information Capsule. Volume 0607
Blazer, Christie
Research Services, Miami-Dade County Public Schools
Recent research has demonstrated that students with normal hearing ability benefit from the use of classroom amplification systems. Amplification systems allow teachers to control, stabilize, and equalize the classroom acoustical environment so their voices are clearly audible over background noise at all locations within the classroom. Studies have found positive effects for students in amplified classrooms, including improved academic achievement and speech perception and increased on-task behavior. Positive outcomes using amplification systems can only be achieved when the existing classroom instruction is effective. In other words, if students are not being provided with strategic instruction, the introduction of classroom amplification systems will not increase their levels of academic achievement or classroom engagement. Teacher benefits include reduced vocal strain and voice fatigue and the ability to move more freely about the classroom. Schools using classroom amplification systems have reported significant decreases in teacher absences due to voice-related problems. School staff, students, and parents have responded positively to the use of amplification systems.
