Métodos PHAT, FLOS-PHAT e ML-Energia para Localização de Fontes de Sinais Acústicos com Características Impulsivas em Ambiente Não-Reverberante.

This paper evaluates the performance of three methods for acoustic signals sources localization with impulsive characteristics. Several simulations were performed considering four impulsive acoustic signals and values of signal to noise ratio (SNR) between 0 dB and 25 dB. In addition, the methods have been investigated for the location where the impulsive noise is additive and is represented by alpha-stable distributions. The results show that impulsiveness acts directly on the final performance of the location.
