Abstract :
Marine noise is a complex audio signal combined by multi-sources, marine noise simulation is one of the important parts in various training and research area such as sonar and ship collision prevention. Based on signal spectrum analysis, spectrums for independent sources in various steady statuses are established, and dynamic spectrum in transiting status is reached with spectrum interpolation. With acoustic spread attenuation model and Doppler effects model, spectrum at listening position is obtained. Time series data of combined noises is generated, and listened noise simulation for multi-sources is implemented finally.
