Induction Loop Testing Equipment
Ambient
Noise Compensation for Sound Field Systems Automatically Adjusts Sound
Field Output
Developed under contract with the U.S. Department of
Education, this
state-of-the-art technology was designed by Oval
Window
Audio to monitor background noise and automatically adjust the
sound
field output. It maintains optimal listening conditions within
classrooms
with varying background noise conditions.
Overcoming Fluctuating Background Noise Obstacles
Studies
have shown that fluctuating background noise, common in classrooms,
adversely
affects students' performance and teachers' health. Unlike typical
sound
field systems, those that are equipped with SmartSpeaker
"Intelligence"
automatically adjust to compensate for changing background noise and
varying
teacher microphone levels. (Click on image for

The results? Field-tested and proven in a study by Crandall, Johnson, Lederman and Smaldino (2001), sound field systems equipped with the $349.00 SmartSpeaker "Intelligence" accessory:
- Increased signal-to-noise ratios by as much as 12 dB.
- Resulted in up to 70% improvement in students' word identification scores (in varying background noise).
- Were touted by teachers who felt it was easier to be heard and that their voices sounded much clearer.
- Were the preferred classroom system by 95% of students polled.
- Come with a satisfaction guarantee. If within 30 days, you are not satisfied with this ambient noise compensation accessory, simply call us at (303) 447-3607. We'll be happy to issue a replacement or a refund.
