PREDICTION AND FULLSCALE MEASUREMENT OF UNDERWATER RADIATED NOISE FROM SHIPS

Since the mid 1970s, Ishikawajima-Harima Heavy Industries (IHI), Japan, has been studying methods for the full-scale measurement, prediction and control of the underwater radiated noise from ships for the purpose of designing and building more silent ships. This article focuses on describing the present status of IHI studies on underwater radiated noise, particularly from ship machinery sources. Some prediction and full-scale measurement results are provided as examples. Although certain important factors in improving the precision of low-frequency and spike noise prediction require further study, it can be said that the prediction method for broadbank underwater radiated noise is close to a practicality.
