In recently years, reduction of noise and vibration has been required for all ships from viewpoint of comfortability. However, the successful reduction on high speed craft is difficult with high power engines to keep high speed. In this paper, study on effect of damping material comprised of two aluminuim plates and thin elastic interlayer for reduction of noise and vibration in high speed craft, is presented. As a step, measurements of noise and vibration on two high speed passenger craft were carried out in both cases with damping materials and without ones to confirm the effects. Furthermore, theoretical calculation were made to study on prediction of effect of damping materials. As a results, it was found that the noise and vibration in high speed craft was reduced considerably with damping materials.
