Diffraction effects in sonar array
, 2014 Humans can localize a sound source with the help of three effects, Head Related Transfer Function (HRTF), Interaural Time Difference (ITD) and Interaural Level Difference (ILD). With help of these three effects humans can sense where in the space the signal is coming from.
