Some measures for noise control of slipway and prediction of noise reduction effect are proposed. An actual case of slipway noise control is taken as an example. According to the characteristic of the slipway noise, a noise source model is built, and the noise reduction effect of these measures for noise control is predicted. The results show that the comprehensive treatment, including sound source control, sound transmission control and production management, is necessary to control the noise. In addition to considering the noise reduction effect, engineering feasibility, cost as well as social factors also need to be considered in building the sound barriers. This work provides a reference for slipway noise control and prediction.
