Monopole Line Source or Point Source,cal Hankel function of the second kind . or the spherical Hankel function of the second kind . and the free-field wave number .. = ./.. with the free-field sound velocity ... Equivalent forms of the point source are:.with the spherical Bessel and Neumann functions j.(.), ..(.).

Reverberation with Mirror Sources,and we effectively failed. After we have demonstrated the application of the mirror source method for the evaluaion of sound fields in rooms (although up to now only in concave rooms) we expect that the mirror source method will be applicable also for the determination of the reverberation time of a room.
