Measurement of HRTF/HRIR for in-ear and hearing aid microphones with respect to the change of distance of the sound source

Head Related Transfer Function (HRTF) describes the characteristic and transformation of sound due to the effect of the head and torso as well as the external ears that provide spatial cues to the human auditory system to localize sound. It has been widely used in the virtual sound spatialization. B...
