An attempt to obtain soft magnetic materials with high saturation magnetic flux density and thermal stability has been carried out with respect to a multilayered type of films containing Fe-N prepared by two-source magnetron rf sputtering. The addition of small amounts of elements such as Al is effective in improving soft magnetic properties of Fe-N films. Multilayered films of Fe-Al-N intervened by thin Si-N layers showed softer magnetic properties than the Fe-Al-N single layer films and also showed high thermal stability. Typically, Fe-Al-N (500 Å)/Si-N (12 Å) multilayered films exhibited a saturation magnetic flux density of 20 kG, a coercivity Hc of 0.3 Oe, and a permeability μ of 1900 at 5 MHz after annealing at 550 °C for 1 h.

Individualization of head-related transfer functions (HRTFs) is important for highly accurate sound localization systems such as virtual auditory displays. A method to estimate interaural level differences (ILDs) from a listener's anthropometry is presented in this paper to avoid the burden of direct measurement of HRTFs. The main result presented in this paper is that localization is improved with nonindividualized HRTF if ILD is fitted to the listener. First, the relationship between ILDs and the anthropometric parameters was analyzed using multiple regression analysis. The azimuthal variation of the ILDs in each 1/3-octave band was then estimated from the listener's anthropometric parameters. A psychoacoustical experiment was carried out to evaluate its effectiveness. The experimental results show that the adjustment of the frequency characteristics of ILDs for a listener with the proposed method is effective for localization accuracy.
