Accurate and effective frequency analysis - source ID and rapid complaint resolution


We have tested many apps. This is a detailed guide to using a very effective free Keuwl Android app for narrow band tonal noise analysis and identification (FFT noise analysis - download for free).
Why use old fashioned 1/3 octaves that are not good at identifying tones and that throw away so much useful identification and diagnostic information when a smartphone FFT app can provide an accurate evaluation?
There can be no valid excuse to rely on subjective impressions or third octaves when tonal noise may be involved.
This is a simple process that dramatically improves noise complaint resolution, source identification and, with our help, BPM/BAT evaluation.
Once you've analysed, what next?
The results of your instant field narrow band analyses may be sufficient. You can determine if there is/isn't a tone or identify whether the tone is from a particular item of plant.
If you need help with tonal noise source ID or the mitigation options, then you can contact us to make use of our free remote analysis service.
