AB  - Previous research has linked vocal sound quality to technique and expressiveness-related movements of singers. This study examines the effect of such movements on vocal directivity data collection and attempts to assess its impact by means of objective data comparisons and subjective user testing. Data was collected from 12 individuals in 29 directions and four elevation planes using a hemispherical microphone array. Data analysis showed that directivity variations range from 1.4 dB to 3 dB, depending on frequency and direction, and that the majority of the differences as measured by the chosen metrics are below the 1 dB JND threshold. The study also conducted auralizations and an audibility test, which confirmed that, in static listening conditions, variations introduced by small body and head movements do not lead to audible directivity artifacts. These findings suggest that measurement protocols allowing for small movements can still capture perceptually relevant and stable directivity data, without sacrificing sound quality.
