BRTF (Body-Related Transfer Function) and Whole-Body Vibration Reproduction Systems
If binaural recorded signals are played back via headphones, the transfer characteristic of the reproduction system has to be compensated for. The transfer characteristic depends not only on the transducer itself, but also on mounting conditions and individual properties of the respective ear. This is similar with reproduction systems for whole body vibration. The transfer characteristic depends to a great extend on the individual body properties, e.g. weight, body mass index. In this study BRTFs of 60 subjects are measured using an electrodynamic excitation system. In addition anthropometric data of the subjects are collected. This paper reviews the existing whole-body vibration reproduction systems and discusses the importance of the individual transfer functions for whole-body vibration reproduction.
