This study assessed sound localisation definition in ambisonic systems using two-non-parametric and three parametric decoders, in a two-dimensional format. The sound samples were played back through eight loudspeakers arranged in a circle. The participants compared pairs of sound samples to determine which sample offered a more precise perception of the sound source’s location. The data analysis, using a Bradley-Terry probability mode, revealed that parametric decoders were preferred with a 60-83% probability. Among the parametric decoders, the COMPASS method, which utilizes the Multiple Signal Classification algorithm for sound source direction estimation, received the highest scores for sound localisation judgements.
