| 内容記述 | Many kinds of ducts are employed in many places for such purposes as water supply and drainage, inhalation and exhaust of gases, electromagnetic wave guides, and transmitting sound. In this paper the dependence of sound propagation in a finite unflanged circular duct and sound radiation from the open end of a duct on duct length and sound frequency is discussed. The sound pressure at the central duct axis, amplitude and phase of the sound pressure at the open end, and the radiated sound pressure directivity were measured. From these values, the end correction, radiation impedance at the open end, and attenuation value were obtained and compared with similar values in other references. The experimental results were explained from the general theory of sound. As shown in table 1 the experimental values are much the same as in other papers and, in cases with different characteristics, they are similar. | |||||||||||||
