The Improving Classroom Acoustics (ICA) special project was designed to determine if students' listening and learning behaviors improved as a result of an acoustical environment enhanced through the use of FM sound field classroom amplification. The 3-year project involved 2,054 students in 94 general education kindergarten, first-, and second-grade classrooms in 33 elementary schools in Florida. The Easy Listener Freefield System[TM] by Phonic Ear was provided in 64 experimental (amplified) classrooms, and the remaining 30 classrooms served as control (unamplified) classes. Analysis of observational data on 1,750 students indicated that students in amplified classrooms demonstrated significant improvement in listening and learning behaviors and skills, and progressed at a faster rate than their grade-alike peers in unamplified classrooms, and that younger students demonstrated the greatest improvement. Data showed that noise levels (dBA) and acoustical treatments in elementary classrooms have not changed over the past decade. FM sound field classroom amplification provided teachers with an average 6.94 dBA increase in vocal intensity. Students, teachers, parents, and school administrators gave FM sound field classroom amplification a positive evaluation. Finally, data demonstrated that this instructional delivery equipment is a cost effective means to manage an important variable in early-grade classrooms--the intensity of the teacher's voice.
