| Here we list several Sound Field Systems by various manufacturers. Set-up is generally simple and maintenance is minimal.
It is fair to say cost is indicative of quality in every manner--set-up, interference, channel selection, quality of sound, and consistent signal strength.
This is a
long-term and beneficial investment. Choose wisely.
Excellent study showing the
effectiveness of Sound Field Systems:

WHY A SOUND FIELD? Enjoy the benefits of creating a Sound
Field in your learning environment. Be in compliance with the Americans with
Disabilities Act (ADA) too.
In its simplest terms, a sound field
amplifies and evenly distributes the volume of the speakers voice to 15db above
the ambient noise level in the room. The result is an environment in which every
member of the audience can hear as if he or she were sitting face to face with
the instructor.
The benefits of such an environment are
many: Attention span improves, productivity increases and audiences tend to
participate more. In short, the more an audience can hear, the more they will
learn and retain. Hard of Hearing students may use their own personal receiver,
if needed.
Another benefit is to the
speaker/teacher. They will not have to raise their voice to be heard. This
results in less strain on their voice, less overall fatigue that goes with
teaching. Speaker/teachers voice can still be clearly heard even when not facing
the audience during times they are writing on the chalkboard, or using an
overhead projector, or walking around the classroom.
