Abstract
The directional perception of human ear for the sound at horizontal plane mainly depends on binaural cues, Interaural Level Difference (ILD), Interaural Time Difference (ITD) and Interaural Correlation (IC). And ILD plays a leading role for human to locate the position of sound with frequency above 1.5 KHz. In spatial audio applications, Inter-Channel Level Difference (ICLD) between loudspeaker signals are used to represent the location information of phantom sources generated by two loudspeakers. For headphone application, ILD and ICLD are approximate, so the perceptual characteristics of ILD can be used as a replacement for that of ICLD. But due to the attenuation influence of the transfer procedure from loudspeakers to humans ears, ICLD between loudspeakers signals are no longer the same with ILD between signals arrive at two ears. And these differences are always ignored in current spatial audio applications such as the perceptual coding of spatial parameters. So in this paper we focus on the analysis and comparison of ICLD and ILD from their formation and their values with different loudspeaker configurations. Experimental results showed that the difference of ILD and ICLD could be up to 55 dB, and the research of this paper may be an important part or reference for further research about spatial audio applications such as coding, reconstruction, etc.
