The Diverging Sound Field of a Spherical Piston
Wednesday, October 17, 1984 12:00 p.m. Halvor Hobæk Department of Physics The University of Bergen Bergen, Norway Computations show that the nearfield of a spherical piston -in the sense that the directional properties are dependent on range- extends much farther out than for a plane source of similar dimensions. The reason for this can be seen by…
