SoundPLANnoise Frequently Asked Questions
Question number FAQ-1073
When predicting factory noise, is sound pressure level or acoustic power level the necessary data for the noise source?
Acoustic power level is required. 1/1 and 1/3 octaves are possible, and the frequency band can be set arbitrarily. It is also possible to calculate the power level at the dominant frequency alone. From Version 7.0 onwards, acoustic power level data for construction machinery has been incorporated into the library for your use.
