A good auditorium must have good acoustics. There should be a speaker’s stand and a few chairs for the presiding officer and others. There should be a mike and speakers in the hall. The hall should be constructed in such a way that the speaker’s voice is clearly heard in the entire hall without strain or echoes. The acoustics and the appearance of the hall can be improved using appropriate special plaster, curtains, wall hangings and absorbent ceilings. The lighting facilities in the hall should be flexible. There should be facilities for increasing or decreasing the intensity of light and changing its color. Adequate facilities of flood light and spot light should be available.
