Keywords:Acoustic wave absorption, Computer monitors, Personal computers, Reverberation, Speech transmission index, Student-activity noises
AbstractA classroom speech-intelligibility prediction tool, applicable to typical classrooms, which is accessible to non-specialist users is developed. As such, the system developed-a Windows system-called the ClassTalk. Class Talk allows a classroom to be modeled, sound-field descriptors to be predicted, and for the classroom and predicted quantities to be visualized on the computer monitor.
