Application of multiple regression method to prediction of A-weighted noise levels in ship accommodation spaces

In about one third of accommodation spaces in ships the required noise level is exceeded. Building of the ‘quiet’ ship requires applying prediction methods at a very early design stage. In this paper a new approach to prediction of A-weighted noise levels and octave band noise levels, based on the statistical multiple regression theory is proposed. The results of this method correspond with the measurement results and the accuracy of this method is comparable with other equivalent methods of prediction of A-weighted noise levels.
