A classroom sound field system will evenly disperse the teacher’s voice throughout the classroom so that every student can hear all the components of speech as accurately as possible. A loud voice does not mean that consonants are louder. It is impossible for a person to make consonants louder and consonants are key to speech intelligibility. An audio system amplifies the parts of speech that give intelligibility and make it easier for students to understand and concentrate on what the teacher is saying.

A Classroom Soundfield System is essentially a small public address sound system, designed for the confines of a typical classroom of 25 - 35 students. From a hardware standpoint, the system usually consists of two wireless microphones. One is primarily for the teacher, and the second microphone is generally used by students. Most sound-field systems are currently using infrared wireless microphone technology. Since infrared is based on pulsating light, the transmission of the wireless microphones will not penetrate the walls of a classroom into another room. This allows us to set up dozens or even hundreds of classrooms very close to [...]
