红外无线语音教学系统应用研究

Research on the Application of Infrared Wireless Phonetic Teaching System

红外无线语音教学系统利用红外光为信号载体，抗干扰性强，背景噪声低，质量稳定，节省广电频率资源，当前在学校广泛用于红外扩音、外语听力播音，以及构建红外语言实验室等。红外扩音与考试系统、红外系统与多媒体教室也可以整合使用。

Infrared wireless phonetic teaching system transmits signals via the signal carrier of infrared light， with the property of interference immunity， low background noise， stable quality， and economy in radio and television frequency resources. This type of system is currently widely used in teaching institutions to infrared PA， foreign language broadcasts， and to build the infrared language laboratory. Further more， infrared PA and examination system， infrared systems and multi-media classrooms can also be integrated.
