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