Abstract
The headphone transfer function (HpTF) is one major source of spectral coloration that occurs in non-individual binaural synthesis. Filters for frequency response compensation can be derived from measurements of HpTFs. Therefore, a reliable method for measuring at the blocked ear canal had to be developed. Subsequently, in comparing dynamic binaural simulations directly to reality we could assess effects of non-individual, generic and individual headphone compensation in listening tests. Additionally, we tested improvements of the regularization scheme of a LMS inversion algorithm, the effect of minimum phase inverse filters, and a method for the low frequency extension by means of integrating a subwoofer.
