Abstract
This paper describes experiments with simulated reflections in an anechoic chamber, in an attempt to understand the importance of early reflections in a concert hall. The subjective effects of a single side reflection were investigated; and the effect of “spatial impression” was identified as the predominant subjective effect. This “spatial impression” was produced for reflection delays between 10 and 80 msec by lateral rather than ceiling reflections.The variation in the degree of spatial impression for variations in different reflection parameters was investigated, as was the effect of two side reflections. It was concluded that the degree of spatial impression is probably related to the ratio of lateral to non-lateral sound arriving within 80 msec of the direct sound. Other authors' theories of the role of first reflections are discussed in the final sections of the paper. Results here gave support to the view that a cross-correlation process is involved in subjective spatial impression.
