Sound source localization is a complex and cumbersome task that most acoustics engineers face on a daily basis. Luckily, there are standard methods to help accelerate the process. Basically, sound source localization methods fall into three categories: near-field acoustic holography, acoustic beam-forming, and inverse methods. Unfortunately, there is not a single “magical solution” to sound source localization, so engineers will have to select one method or another, depending on the test object, nature of the sound, and the actual environment.
Read about sound source localization theory to determine which of the three methods is the best one for your job.
