Article discussing the use of sound-field amplification systems in classroom settings. Classroom sound-field systems are public address systems that include wireless microphones. As the teacher talks into the microphone, his or her voice is transmitted to a specialized receiver/amplifier that is connected to, or physically a component of a loudspeaker assembly. The purpose of the system is to ensure that the teacher’s voice is clearly audible above the inevitable background sounds that occur in every educational setting. Research has demonstrated that although sound-field systems were initially designed for children in special education classrooms, children without hearing impairments can benefit from them as well. Teachers have responded positively to the systems, as they are prevented from raising their voice more than necessary.
