ABSTRACT

In the results from Barron (1971) that were shown in Figure 6.13, this description was given of what a listener perceived when a single refl ection was added to a direct sound: “The source appeared to broaden, the music beginning to gain body and fullness. One had the impression of being in a three-dimensional space.” One can imagine that more refl ections from different directions would intensify the effects. Barron bundled the perceptions under one name-spatial impression-but it obviously embraced multiple audible effects related to the following:

■ Image broadening-“the source appeared to broaden”

■ Timbral enrichment-“body and fullness”

■ Spaciousness and envelopment-“the impression of being in a threedimensional space.” The experiments were done in an anechoic chamber, and the single refl ection gave the listener a sense of being in a refl ective room.
