AB  - In this paper a method for estimation of individual Head-Related Impulse Responses (HRIRs) from impulse responses acquired in an ordinary sound field is proposed based on the Spatial Principal Components Analysis (SPCA) of the HRIRs. The average vector and the principal components matrix are assumed to be obtained by adopting the SPCA to the set of HRIRs of multiple subjects covering all directions. A part of the impulse response from sound source to an ear of a certain subject, regarded as one of his/her HRIR, is used together for estimating the weight coefficients of the principal components. Applying the method using the dataset involving the HRIRs of the multiple subjects covering all sound source directions to the estimation of the individual HRIRs showed that the acceptable estimation accuracy is obtained for the estimation of the HRIRs in an ipsilateral direction.
