On the low frequency characters of head-related transfer function

  • A method to correct the measured head-related transfer functions(HRTFs) at low frequency is proposed. By analyzing the HRTFs from the spherical head model at low frequency,it is proved that below the frequency of 400 Hz,amplitude of HRTF is nearly constant and the phase is linear function of frequency both for the far and near field.Therefore,if the HRTFs above 400 Hz are accurately measured by experiment,it is able to correct the HRTFs at low frequency by the theoretical results.The results of calculation and subjective experiment show that the proposed method is feasible.
