Estimation of Magnitude Response of Reflecting Loudspeaker System in Listening Area Using Near-Box Measurement

This paper presents a simple and robust method to estimate the general magnitude response in reflecting loudspeaker systems. The method utilizes statistical acoustics and is based on near-box impulse response measurement. This measurement holds information across the entire listening area after truncation post-processing. The estimation was investigated in different acoustic environments, which lead to that the more diffusive the room is, the more precise result can be achieved. Measured response can be a reliable reference for correction system in reflecting loudspeaker system.
