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.
