Abstract	As school performance under NCLB becomes increasingly important, districts can not afford to have barriers to learning. That is where wireless sound-field amplification systems come into play. Wireless sound-field amplification systems come in two types: radio frequency (RF) and infrared (IR). RF systems are based on FCC-approved FM and UHF bands (commonly used for radio and television, respectively), and IR systems use infrared light to send signals between a microphone and receiver. The systems consist of a handheld or headset mic, a receiver, and a set of speakers (external, in-ceiling, or in-wall models). When it comes to sound reinforcement in the classroom, districts have a host of options to choose from. In this article, the author looks at wireless, permanently installed systems focused on amplifying speech, not music. (ERIC).
