本文报道了互功率谱相位分析(CSP)作为一种精确的时延估计(TDE)技术的应用,并将其应用于麦克风阵列系统中,用于噪声和混响环境中的声事件定位。介绍了一种相应的相干测度(CM)及其图形表示,以显示TDE的精度。真实的实验表明,在6米× 6米的区域内,平均定位误差小于10厘米。
This correspondence reports on the use of crosspower-spectrum phase (CSP) analysis as an accurate time delay estimation (TDE) technique, It is used in a microphone array system for the location of acoustic events in noisy and reverberant environments, A corresponding coherence measure (CM) and its graphical representation are introduced to show TDE accuracy, Using a two-microphone pair array, real experiments show less than 10 cm average location error in a 6 m x 6 m area.
