Near-Filed Measurement of an Array Loudspeaker in an Anechoic Room

HAN Yi-ping;MENG Zi-hou;Communication Acoustics Laboratory,Communication University of China;  
In a large anechoic room, used the scanning method to measure the near-field acoustic characteristics of a line array loudspeaker system, including the directivity, the quarter-power angle. The on-axis responses get fitted, and the results showed that the trend of the quarter-power angle is different from the theoretical trend, and the wave of on-axis responses is fluctuating. The near-field measurement results could be considered as the basis for evaluating a line array loudspeaker system.
