A linear four microphone array can be employed for acoustic event location in a real environment using an accurate time delay estimation. This paper refers to the use of a specific technique, based on crosspower spectrum phase (CSP) analysis, that yielded accurate location performance. The behavior of this technique is investigated under different noise and reverberation conditions. Real experiments as well as simulations were conducted to analyze a wide variety of situations. Results show system robustness at quite critical environmental conditions.
