Classroom Audio Systems

 We continue to extend the widespread use of audio amplification systems in our classrooms. 
There are more than 50 classrooms across our District using a product sold by Lightspeed.  They provide a robust and even sound in the classroom with any digital media played and a paired classroom microphone.

There are two styles of lightweight microphones in use, worn on a lanyard by the teacher.  They are paired with the systems via Bluetooth, which has shown great reliability. 

The batteries have done well to hold power for a full day of teaching after being charged overnight.
  They seem to get about 3 years of good use before needing replacement.

There are 3 models of Lightspeed Audio System in our classrooms:

Redcat

This is a portable unit that works well in classrooms that do not have a suspended ceiling.  They are used at some of our elementary buildings, and are often placed on a shelf.   They are also helpful where portability is needed.  This unit does need to be plugged in.  However, a rechargeable battery pack may be added.


 


TCQ, paired with a 975 amplifier

 This model is best used in classrooms where there is no power in the ceiling.  This would include our K-2 classrooms that use Promethean Display Boards at both Bailey Park and Fairview.  The amplifier is tucked out of the way and plugged into a wall outlet.  

 


Topcat

These are best used in classrooms with a ceiling-mounted projector, such as the middle school or high school.  These are the easiest to install and maintain.  They are plugged into a ceiling outlet.  

These classroom units have been an integral part of many teachers' daily routine.  They provide a universal accessibility for all students by adding 'round' sound to the room, balancing a normal tone throughout the room and reducing the need for more volume... and the stress that goes with it.  This stress is two-fold:  the physical stress and fatigue on the teacher working to extend their voice in the room and the student stress of having a teacher using a loud voice much of the day.  It is a benefit for every student, including those who have learning barriers, both diagnosed and undiagnosed.


Objectives and Mentality:

Our objective with teacher audio is to create ‘round’ sound in the classroom and not ‘loud’ sound.  We want the audio of the teacher’s voice to reach evenly around the room, regardless of which way they are facing or where they are in the classroom.  If the teacher can hear their own voice or if there is a squeal of audio feedback, then the speaker is turned up too loud.


Using a classroom audio system is a universal accessibility feature, that is, it is a benefit for every student in the classroom, including those who have diagnosed and undiagnosed learning challenges.  It allows teachers better reach to students and reduces the need for proximity placement for some.
