It is well known that good acoustical design should optimise room acoustics and minimise unwanted noise so that effective speech-to-noise ratios are maximised in classrooms. However, the common experience of difficult speech communication in many rooms is evidence that many problems remain. A review of the literature shows that reported noise levels in classrooms almost always exceed ideal criteria, but these results may be questioned because it is difficult to measure the speech and noise levels that occur during actual speech. Many criteria are based on studies that show a poor understanding of room acoustics and tend to prescribe more absorptive environments ignoring the positive effects of early reflections. The more stringent requireme...
