An empirical method for prediction of noise levels in ships is presented and the problems involved in the development of the method are summarised. The main problem is that different ships show large differences in bending-wave attenuation figures per deck. Problems involved in getting proper input data to the calculation steps concerning structureborne sound transmission between steel structure and cabin linings as well as radiation of sound into the cabins are discussed briefly. Some results of preliminary calculations with SEA-models using up to 25 subsystems are reported. Although the results are encouraging, more work needs to be done to confirm the validity of the method, particularly with respect to larger systems and other reference ships.
