Multizone soundfield reproduction has drawn the researchers' attention recently. The paper introduces a soundfield rendering system for a simultaneous reproduction of sound sources with different elevations over multiple listening areas using a linear loudspeaker array. A novel method based on the usage of HRTF (Head Related Transfer Function) spectral elevation cues in conjunction with a horizontal multi-zone sound rendering system is proposed. The proposed method is in a dual-band manner and it aims to accurately reproduce the desired 3-D elevated sound with the consideration of HRTF cues within the selected listening zones, while also minimizing the sound leakage to the targeted quiet zones over the entire audio frequency range. A listening test is conducted and the results confirm the feasibility of simultaneous multizone soundfield rendering with different elevation using a single 2-D loudspeaker array.
