Musical instruments are considered natural sound sources with specific directivities. Each instrument unique directivity needs to be identified and implemented in auralization of sound in room acoustic designs. This paper shows detailed directivity measurements on selected musical instruments, human voice, and impulse sources used in room acoustics design under realistic conditions. This work presents results that are measured using acoustic beamforming techniques. Measurements are based on simultaneous recording using a hemispherical array of 120 microphones. The directivity data are measured and analyzed in the time, and frequency domain, and effects in the near field of musical instruments are explored. Dynamic variations in the musical instruments’ directivity relative to sound power, loudness (intensity, pressure), projection, and the apparent size of the sound or volume are presented. Recorded data are presented in static or dynamic mode as well as in both 2- and 3-dimensional format using the beamforming software as well as Math lab algorithm. The results of this work are applicable toward improvement in the quality of auralization of musical instrument in simulation tools and vocal production studies and room acoustic sound filed. Evaluation of their projected radiations’ pattern contributes to a more realistic acoustic design simulations or virtual reality applications.Musical instruments are considered natural sound sources with specific directivities.
