Judgment of Sound Source Location in Semi-Enclosed Space Based on Sound Field Simulation

This study investigates the determination of sound source positions within the sound field of a small semi-enclosed space, utilizing finite element simulation based on wave acoustic theory. The acoustic simulation of the sound field is conducted using Abaqus CAE. A comparative analysis is conducted to assess the sound pressure characteristics of the sound field under varying frequencies in both enclosed and similarly sized semi-enclosed spaces. Furthermore, the study examines the characteristics of the sound field and sound pressure at different frequencies within semi-enclosed spaces with varying sound source locations. By analyzing these characteristics, the specific location of the sound source is accurately determined.
