** THE MOST SUCCESSFUL SOUNDFIELD SYSTEM IN EUROPE IS NOW DISTRIBUTED IN AUSTRALIA! **
** NOW THANKS TO OUR DIRECT PURCHASING (and smaller sales margins), SCHOOLS CAN BENEFIT FROM THIS EXTREMELY USEFUL TECHNOLOGY AT AROUND HALF THE PRICE OF THE TRADITIONAL SOUNDFIELD SYSTEMS **
The Linkx IRA 89 is a complete sound field system designed for installation is class rooms.
Each sound-field system kit consists of an infrared wireless microphone worn by the teacher, which is transmitted via loudspeakers placed strategically around the room. The system increases the teacher’s voice level and also decreases the distance from each child to the teacher’s voice, which removes the problems associated with reverberation.
In an experiment conducted by NAL, the use of sound-field systems resulted in a 41 per cent increase in the rate of attainment of educational indicators during the terms the systems were installed. This was averaged across all children in the classes and across reading, writing and numeracy skills and occurred despite most of the children having no problems with their hearing.
What is the Science behind a Sound Field System?
As with a magnetic field, sound also weakens by the square of the distance. The sound wave amplitude drops off by the square of the distance. This is calculated by the distance being multiplied by itself.
For example, the child sitting at a teacher's side one metre away hears very well. A child sitting two metres away hears four times less. Four metres away, eight times less; and a child ten metres away (10 X 10) hears 100 times less! These children at a distance from the teacher are off task, more easily distracted or looking elsewhere more frequently than those who are closer.
There are several points to consider here:
* Children spend 45% of the school day engaged in listening activities
* Children's auditory processes aren't fully developed until their mid-teens
* Even in an acoustically sound classroom, children receive 83% of a teacher's voice when they sitting in the front row; 66% in the middle rows and only 55% in the back row
* Children do not perform well in noisy environments compared to adults
* The ability to listen in noisy environments is not developed until adolescence
* The average primary school student misses 25% of what a teacher says Children need a quieter environment and a louder signal in which to learn. This is what Sound Field Systems set out to achieve.
