Preface
This book describes the latest findings from the fundamentals to applications of the head-related transfer function (HRTF). The HRTF plays a primary role in human perception of the direction of sound. By applying HRTFs, the three-dimensional acoustical sensation of an existing sound field (at concert halls, stadiums, or disaster sites) can be reproduced, and/or that of an imaginary sound field can be generated for video games and cinemas, independent of time and space. Such systems are currently being developed. Starting from the 1960s, when studies on HRTFs became active, a number of researchers around the world have obtained various findings. Considerable fundamental knowledge on HRTFs has been accumulated. However, no major breakthrough has been found in the application of HRTFs. At present, a truly threedimensional acoustic VR system for practical consumer use does not exist anywhere in the world. One of the principal reasons for this is that the problem on individual differences in HRTFs has not been solved. Blauert’s scenario was introduced in M
