In this paper, we present a study to improve using neural networks for acoustic reflection localization. Our study focuses on the reimplementation of the proposed neural network model by Bologni et al. and investigates the effect of adding a third microphone to the microphone array. We reimplemented and trained the neural network using the same framework and hyperparameters as the original model, and then evaluated it using the same metrics. Our results show that the addition of a third microphone improves the amount of detected sources from 43% to 58%, it also improved the front-back ambiguity from 25% to 18%. Conclusively, have demonstrated the potential benefits of adding a third microphone to the neural network approach for acoustic reflection localization.
