Abstract:
Musical instruments often have rather complicated radiation characteristics which have been documented for the case of free-field radiation. This paper studies the effect of the source location relative to the room boundaries on the sound radiation from musical instruments in rooms. The musical instrument is modeled by the equivalent source method, or source substitution method, so that the real source is replaced by a set of simpler sources which approximately reproduces the vibrations on the instrument’s surface. A single corner with rigid walls is used to model the effects of the room boundaries on the sound radiation. As an example, a tympani is studied and theoretical expressions for its surface vibrations are used as input data. The directivity, and total power output, are then studied for various source locations. Possibilities for simplified source directivity modeling for room acoustical simulation are discussed.
