JIANG Bo,HAN Jie(National Testing and Inspection Center for Radio & TV Produets of China,Beijing 100015,China)
The new 3D turntable can measure the loudspeaker′s vertical directional characteristic,and any angle of loudspeaker′s frequency response.The loudspeaker′s 3D polar radion measurements are designed and loudspeaker′s balloon model is defined by AES56—2008.According to this standard,3D polar radion measurement is provided.And it compares with the measurement of normal directional measurement.
