✦ Synopsis

A BSTRA CT

To obtain the geometry of a sound source with omnidirectional emission which better simulates the piano as a musical source, for the calculation of sound levels in closed rooms, it is compared, by means of a theoretical model implemented in a computer, with three different sound sources: spherical point, ellipsoidal point, and line. The model has been devised for these three sources, taking into account four directivities for each of them: omnidirectional revolution, with planar symmetry, and without any symmetry. It has been verified by means of the experimental data obtained in three different halls, using a pattern sound source. The experimental data obtained from the piano and the theoretical model results are compared in order to study the relationship between them.
