The resolution of directional perception of spatially distributed sound sources was investigated with a listening test in an anechoic chamber using various sound source distributions. 15 loudspeakers were used to produce test cases which included sound sources with varying widths and wide sound sources with gaps in the distribution. The subjects were asked to distinguish which loudspeakers emit sound according to their own perception. Results show that small gaps in the sound source were not perceived accurately and wide sound sources were perceived narrower than they actually were. The results also indicate that the resolution for fine spatial details was worse than 15 degrees when the sound source was wide.
