Sound Power Estimated by a Proposed Acoustic Intensity Method in Production Field

Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes a full vector intensity measurement system developed here and a procedure for sound power determination based on minimum measurement data (ln models) [1] in production field is experimentally discussed. The probe has three pairs of microphones at equal spacing of 12 mm that set up in each of the x, y, and z directions and share the same observation point. The sound field calibration method using a precision sound intensity measurement system (RION Co., a probe SI-21, which has a maximum intrinsic phase mismatch of 0.25 degree at 150 Hz, and a FFT analyzer SA-74) is effective to correct errors. Consequently, it is possible to reconstruct only parts of a constant voltage transformer (Ichikawa Co., CVT) emitting the most noise (120 Hz and 1,325 Hz) and measure efficiently the sound power level.
