Free Database of Head-Related Impulse Response Measurements

We have measured a set of horizontal plane Head-Related Impulse Response (HRIR). The impulse responses were acquired in an anechoic chamber using a KEMAR manikin at four different loudspeaker distances – 3m, 2m, 1m and 0.5m – reaching from the far field to the near field. The loudspeaker was positioned at ear height and the manikin was rotated with a high-precision stepper motor in one degree increments. Besides the raw HRIRs also datasets are available which have been compensated for the use with specific headphone models.

    is it possible to download the database as a non-member?
    I just did study at the TU. I am looking for impulse responses like those you created for private interests only.

    Hi Piet.

    Yes, the link was broken. You can find the database here:

    The link requires a login. Is there a direct link available?
