| Abstract(in English) | One of the most important problems of sound field control is that the room transfer function is changed drastically by the environmental change. In order to control the sound filed for a long span, we need to meaure the transfer function frequently or to adapt against the fluctuation. If we assume that there is no environmental change except temperature chage, we could assume that all the changes of transfer function is time axis scaling of sounds. In this paper, we propose the model using Taylor expansion to estimate the transfer function which changed by temperature change. Using this model, we can estimate the change of transfer function when the temperature chage is as small as 0.1℃. We can also estimate the impulse response change if it is smooth enough to get its derivative |
