抄録

The following have been understood from this report.<BR>1. The data of the acceleration noise for 18 PWCs sold in Japan was obtained.<BR>2. The guideline to reduce the noise of PWC which make it meet the regulation or the restriction was obtained.<BR>3. The measured data almost meet the theoretical value about the distance attenuation, but in some area the effect by geographical features is necessary to be considered on the way to drive PWC.<BR>4. The frequency element which originated in the number of cylinders of engine and the number of wings of the internal propeller was shown.<BR>5. The time of the maximum of the acceleration noise did not meet the time of maximum revolution of engine. It is an appropriate way to measure the acceleration noise to evaluate the noise of PWC.
