ABSTRACT OF THE DISCLOSURE A method for optimally determining sensor positions for an acoustic pyrometry, which is capable of obtaining a minimum number of sensors satisfying a given error limit on the basis of an effective independence method and determining positions of the obtained number of sensors suitable for error minimization. A predetermined number of sensors are arbitrarily arranged on sides of a rectangular sectional area to be measured and a transfer matrix is calculated with respect to positions of all the sensors. Then, effective independence values are obtained for respective paths of each of the sensors by performing singular value decomposition with respect to the calculated transfer matrix and a total effective independence value of each of the sensors is obtained by summing up the effective independence values obtained for the respective paths. Subsequently, one having a smallest one of the obtained total effective independence values is removed from among the sensors and the above steps are repeated until the number of the remaining sensors becomes equal to a target value. The target value is set to be larger than a minimum number of the sensors, which is found by calculating variations in a conditional number of the transfer matrix while the sensors are reduced in number and detecting a point where the conditional number increases abruptly.
