Abstract

    For the acoustical design of comfortable environment in a car, authors have been applied the Finite-Difference Time-Domain method as a numerical simulation method. In a previous research^{1, 2)}, on the basis of the assumption of an extended reacting boundary, the analytical model considering wave propagation inside seats was introduced. By comparing the actually measured and calculated impulse responses inside the car cabin, the predictability of the model was investigated. On the other hand, for the car interior design in consideration for easiness of making conversation, sound field analysis taking into account the effect of the listener/talker’s direction during conversation should be used. For the purpose, in this study, the calculation method modeling of the shape of head and torso was examined.<br>
