The authors investigated the effect of changes in the acoustic signal propagation speed and the accuracy of sensor
positioning on the accuracy of sound source localization. The mean absolute error grows with the displacement of the microphones
relative to the nominal coordinates (X, Y). The same trend is observed with an increase in the actual acoustic signal velocity
deviation from the velocity under normal environmental conditions.
The authors propose two ways to reduce the error caused by these factors. The first method is to introduce a correction
factor for the speed of the acoustic signal. The second method is to reduce the distance between the system's sensors. This makes it
possible to place them more accurately relative to each other.
