Sound field rendering technique is becoming possible to reproduce it accurately with recent computation power. Furthermore, multi-channel sound field system can be realized with low-cost digital-to-analog converter modules. Moreover, some researchers are trying to implement sound field techniques with over-hundred-channel loudspeaker arrays. However, we cannot physically reproduce up to 20 kHz because of spatial aliasing. We must use an incomplete system currently. Threfore, we have to investigate whether it’s possible to discriminate sound fields, which are different in upper-limit frequency of the spatial aliasing with virtual environments. As a result, listeners cannot discriminate the sound fields over 4 kHz. |
