Active Radiating Factor (ARF) is an important parameter to analyze the loudspeaker line array when considering the gaps between each two radiating transducers. The relation between ARF of the loudspeaker line array and the Differential chart of its Frequency Responses in two distances (FRD) is analyzed. Some valuable conclusions about ARF and FRD are found. A method to estimate ARF by measuring frequency responses comes out.
