artithe intelligent virtual environment in an

artificial fish of virtual auditory system is designed in this

paper. Firstly, the model of artificial fish of auditory system in

intelligent virtual environment (IVE) is built. Secondly,

two-layer of artificial fish of auditory perception is designed

according to the biological mechanism of auditory. The first

layer is based on the design of the low frequency signal. The

second layer is based on the design of the high frequency signal.

And using the bayesian network(BN) to realize the acoustic

signals of artificial fish to learn and memory algorithm. Get a

satisfactory result through animation simulation.
