True but I can tell you that if we even make 75dB noise per car the neighbours are still complaining keeping tracks in their grip. It is noise outside normal noise and on a higher frequency making it more anoying.
I am convinced some organisations do use the noise as an issue as a steady income through the homologation proces.
