Near-field head-related transfer functions (HRTFs) are essential to scientific researches of binaural hearing and practical applications of virtual auditory display. In contrast to far-field HRTFs measurement, the near-field measurement is more difficult because high efficiency, accuracy, and repeatability are required in a near-field HRTF measurement. When multiple sound sources are adopted to accelerate the near-field HRTF measurement, multiple scattering among sound sources could be the major factor to influence the accuracy. In the present work the well-designed multiple sound sources solution is used to accelerate the near-field HRTFs measurement. Results show that the error caused by the multiple scattering among sound source can be controlled within the acceptable values through reasonable design and arrangement for sound sources.
