电教用房声音处理的探索与研究

Exploration and Research on Dealing with the Sound in Audio-Visual Room

电教用房的室内声音包括直达声、前期反射声和混响声。本文运用室内声学、建筑声学和电声学的理论知识，从室内混响声和最佳混响时间入手，探讨了电教用房的几何尺寸、吸声材料、吸声结构、隔声降噪等声音处理方法，并对室内音质改善提出了两种解决方法。

The indoor sound in audio-visual room consists of through sound, early reflex sound and the reverberations. The article using the theory of room acoustics, architecture aooustics and electrical acoustics, starting with indoor reverberations and the best reverberation time, discusses many methods in dealing with the sound in the geometrical size, the smallest volume, sound-absorbing materials and sound-absorbing structure, sound insulation and noise reducing, also advances some ways in making further improvements about tone quality.
