AbstractThis study explored the target sound source location at unknown situation and processed the received signal to determine the location of the target, including the reconstructed signal of source immediately. In this paper, it used triangulation sound sources localization and time reversal method (TRM) to reconstruct the source signals. The purpose is to use a sound source localization method with a simple device to quickly locate the position of the sound source. This method uses the microphone array to measure signal from the target sound source. Then, the sound source location is calculated and is indicated by Cartesian coordinates. The sound source location is then used to evaluate free field impulse response function which can replace the impulse response function used in time-reversal method. This process reduces the computation time greatly which makes possible for a real time source localization and source signal separation.

A series of experiments, in which the sample gas of a gas chromatograph has been perturbed with a pseudo-random binary sequence, is described. The detector response was cross correlated with the input to obtain the system impulse response, which, in this case, is proportional to the chromatogram. The experiments were carried out to determine the advantages and disadvantages of this technique compared with the conventional (single sample injection) method, and it is concluded that, while the technique is most unlikely to be used as a straight replacement for the conventional method, it could prove useful where a rapid qualitative indication of a composition change is required.
