In all homeroom classrooms and many of the enrichment classes, teachers are able to utilize a sound-projection system that operates on radio frequency, provided by Lightspeed Technologies. This microphone system amplifies the voice of the instructor or of students who use the microphones when reading aloud or presenting to the class. This system has been found useful when working with children who have diagnosed auditory processing issues. Also, research indicates that if the voice of the teacher is amplified even slightly over ambient noise in the classroom, students attend to the auditory information with more efficiency than in classes that do not have voice projection technology.
