Califone encourages the use of published peer-reviewed research supporting individual, small group and classroom-wide sound amplification. These references are intended only as beginning reference points and n expanded list of journals and original source materials can be found from some of these association web sites.

In order to organize the following research so it might be more readily accessible to certain products, we have grouped them by the following categories.

Classroom Wide Audio Amplification

The leading instructional tool to increase fluency is for students to hear fluent reading daily. Oral reading can, indeed, foster comprehension. By listening to their teacher read aloud to them over the course of the school year, students achieved better vocabulary and comprehension skills than students who have not been read to regularly by the teacher.

The study goes on to conclude that students being taught in an audio rich environment are showing massive gain in reading on state Criterion-Referenced Competency Test.
