Young people spend at least 45% of their school day engaged inlistening activities, with today's classroom acting as a primarily auditory verbal environment.

However, a recent study in the journal of the American Medical Association showed that 14.9% of children aged 6~19 suffer from some degree of hearing impairment, either permanently or temporarily due to illness, infection or allergies.

Studies estimate that 80% of school children will have some form of hearing loss during an academic year and, with the importance of auditory learning in the classroom, the use of technology to enhance listening performance ultimately allows children to learn more efficiently.

One of the simplest and most effective solutions is a 'Sound Field Voice Reinforcement System'. Functioning like a mini public address system in harmony with the classroom acoustics, Sound Field Voice Reinforcement features a wireless microphone, receiver, amplifier and between one and four loudspeakers (dependent upon the size of classroom).
