Car road noise exceeds music spectra below about 200 Hz

Evidence

All of this is made directly relevant by the set of music spectra slicing through the middle of the display. These come from measurements done by Olive (1994) and represent four programs exhibiting unusually flat and extended spectra. These are long-term average spectra, which ignore whatever dynamic range the program had. The background car noise exceeds these spectra below about 200 Hz, explaining why car audio systems need large bass boosts at highway speeds. — Toole, Floyd E, Sound reproduction- the acoustics and…, 932
