Analysis of Factors Contributing to the Sound Generated by Airboats

چکیده
Due to the large increase in Florida’s lakefront communities, the issue of noise generated by airboats has become very important. In response to this matter, Florida Fish and Wildlife Conservation Commission requested a study to determine the major factors and their contribution to the sound generated by airboats. In this study the effect of engine speed, engine type, muffler type, number of blades, blade’s size, and boat structure were analyzed. More than 450 stationary and drive-by sound level measurements were taken, using 15 different boats. This paper presents the analysis of the sound contributors using a factorial analysis model.

متن کاملNoise pollution analysis in Tehran cement plant
Background : Cement industry has many process units. Basically all of these units can be considered as a source of noise. Since noise pollution is defined based on its offensive hearing effects, the importance of the noise sources depends directly on the number of workers in the unit. Materials and Methods : An experimental study has been done at Tehran cement factory to recogn...
