Room acoustic parameters vary greatly with the position of the receiver and the source, so that we cannot extract exhaustive information about the room acoustics from independent single-point measurements. Using array measurements permits to predict the sound field with a high spatial resolution and leads to a more precise assessment of the room acoustic properties. We propose an array technique to investigate room acoustics by reconstructing the volumetric sound field from measurements taken on a sphere using methods of Nearfield Acoustical Holography (NAH). A virtual spherical single-microphone-array was constructed and successfully tested in room acoustical modal analysis.
