Sure, you can measure noise (of all kinds) with your iPhone or Android phone. That may (or may not) tell you something regarding the noise level in your facility or area. Truth is, though, that’s not the whole picture.
What is really important is the actual distribution of the frequencies.
That’s where spectral/spectrum analysis comes into play.
We can measure in 1/1 or 1/3 octaves the actual noise levels from 8 Hz on to the 20 kHz band. If necessary we can actually perform subsonic, or ultrasonic measurements to determine the actual noise emissions in situ.
