Soundfield Systems


What are Soundfield Systems


Soundfield systems are speech amplification systems that allow all children to hear the class teacher clearly in all parts of the classroom. The teachers’ voice is seamlessly distributed to all areas of the room meaning that no student is put at a disadvantage because they are not in close proximity the teacher.




Why do we need Soundfield systems?

There are three main obstacles that need to be overcome to enable the delivery of good learning and understanding in all teaching spaces:


The clarity of our voice dramatically declines when we are more than 1 metre away from our audience (students). It is imperative that students are able hear and understand what teachers are saying.


Noise can be generated by traffic outside, other classes within the school, background noise from within the classroom (from the students, the projector or even the heating system).


Echo caused by sound bouncing off of hard surfaces ie Windows, Walls, Celling, doors and furniture. Generally as reverberation increases the harder it is for students to understand the teachers.

The issue of distance exists even in the best acoustically treated rooms and the best way to overcome this is by using a Soundfield system to reduce the effects of distance and improve the signal to noise ratio.

How do Soundfield Systems work?

Soundfield systems work by the teacher wearing a small microphone around the neck that sends the teachers voice to special speakers within the room. The speakers distribute the teachers voice throughout the classroom at a very comfortable volume level providing even sound distribution, making the teachers voice ultra-clear to all.

Types of Soundfield Systems


There are three main types of system; Fixed (installed into the classroom), Portable (can be easily moved from room to room), Movable (can be moved occasionally when needed).

Fixed Soundfield Systems


A fixed Soundifled System comprises of a base unit usually located on the teaching wall, a teacher’s microphone and speakers, usually four, depending on the size of the room and usually wall mounted.

The teacher uses the microphone providing clear communication throughout the whole classroom evenly distributed by the fixed wall speakers.

The Soundfield base unit is connected to the teachers laptop/PC also providing clear sound reproduction of any video or music content used throughout the day.

As example of a fixed system would be the Lightspeed 955 Access Soundfield – this uses the very latest sound transmission technology utilising a digital signal ensuring no interference or drop out of signal.
