摘　　要：扩声系统是一种直接关系到师生生理、心理健康及教学质量的教学设备,但人们往往忽视其重要性。通过实验,研究了一种新型的无线数字教学用扩声系统以及一种传统的模拟便携式扩声设备在实际教学环境中的语言清晰度,并分析了它们为师生所提供的教室室内听闻环境。As a very important kind of teaching equipment, sound reinforcement system produces a direct effect on the health of teachers and students, physically and psychologically, and the quality of teaching. But the importance and effect are usually ignored. As shown in this paper,the speech articulation of a new type of wireless digital sound reinforcement system for teach- ing and a typical kind of portable analogous speaker are studied, by experiments in practical environment of teaching applica- tion, to analyze the acoustic environment which they provide for teachers and students.
