Acoustic Power Level Measurement System for Construction Machinery CAT-SA02-CPWL

Designed for measuring acoustic power levels of construction machinery, the computer running the software controls a multi-channel signal analyzer of the SA-02 series to acquire 1/3 octave band acoustic power levels.
Sound pressure level values are measured for six measurement points arranged on a hemispheric virtual measurement surface (fixed point method), and data for levels produced by the operating sound source are compiled by the computer.
