Abstract
Starting from human subject feeling, ship-radiated noise beat tune future is researched based on psychoacoustics. The relationships between beat tune and the shaft frequency harmonic structure of DEMON are found. Harmonic structures between targets of different types are different, and beat tunes are also different. A new feature-modulation degree-is distracted, that can be an important judge in target classification. The influence of noise frequency to beat tune is also analyzed.
