There are three main approaches to predict the noise level : similitude structure method including the frequency - response method and proportion method , modal method including finite element method ( fem ) and boundary element method ( bem ) , and statistical energy analysis ( sea ) . the advantage of similitude structure method is to give the predicting data fast , but it has some error because of dealing with rough similitude parameter and mass load
