Methods of Measuring a Classroom´s Indoor Audio Environmental Parameters

Reverberation time and language definition is an important parameter to weight the auditory environment in classrooms. By analyzing the indoor environment of classrooms, a new method was put forward in which the acoustics parameters was educed by using neural network. Comparing with other methods, the method built the connection between the environment character and reverberation time and language definition in classroom and gained the better deducing accuracy. It provided a new thought about research of inner-classroom audio environment and design of classroom acoustics.
