Creation of 2D Sound Source Location Maps for Acoustic Source Localization

In acoustic source localization, 2D sound source location maps serve as valuable tools for determining sound source positions and helping engineers better understand acoustic environments. These maps can simultaneously display sound source locations from multiple directions, providing comprehensive spatial information. To create accurate 2D sound source location maps, specialized acoustic software and hardware equipment are essential. The implementation typically involves signal processing algorithms such as cross-correlation techniques or beamforming methods to capture and analyze sound signals. Key functions include time-delay estimation between microphone pairs and sound intensity calculations for position triangulation. The process requires careful attention to technical considerations, including proper microphone array configuration, sound level calibration, and coordinate system alignment. Through correct implementation of these tools and techniques, engineers can create more precise and detailed sound source location maps, enabling better understanding of acoustic environments and supporting informed decision-making in applications like noise control, acoustic design, and source identification.
