Correspondence Relationship between Physical Factors and Psychological Impressions of Microphone Arrays for Orchestra Recording

Microphone technique for surround sound recording of an orchestra is discussed. Eight types of well known microphone array recorded in a concert hall were compared in subjective listening test on seven attributes such as spaciousness, powerfulness and localization using a method inspired by MUSHRA (MUltiple Stimuli with Hidden Reference and Anchor). The result of the experiment shows similarity and dissimilarity between each microphone array. It is estimated that directivity of a microphone and distance between each microphone are related to the character of microphone array and these similarities are changed by music character. The relations of the physica
