Pulsed neurons are suitable for processing time series data, like sound signals, and can be easily implemented in hardware. In this paper, we propose an aural information processing system based on the human auditory system using a pulsed neuron model and a correspondent implementation in an FPGA device. Experimental results show that an FPGA based implementation of the proposed system can successfully identify the results faster than a similar software implementation. Noise tolerance experimental results are also presented.
