抄録

Errors involved in bending vibration intensity measurement consist of systematical errors due to finite difference and random errors. Both errors are investigated through analysis and experimentation. A correction factor is proposed to minimize the errors due to the finite difference for the general measuring condition. The following results are obtained. ( 1 ) The method which uses 9 measuring points is recommended for measuring the intensity in a far-field condition. ( 2 ) The condition to minimize the random errors is proposed; the product of wave number k and the space Δ between sensors is specified in the paper. ( 3 ) The method which uses 4 measuring points gives a larger value than the actual one.
