No accepted method rates subjective acceptability of ambient noise spectra

Evidence

NC contours are not ideal background spectra to be sought after in rooms to guarantee occupant satisfaction, but are primarily a method of rating noise level. There is no generally accepted method of rating the subjective acceptability of the spectral and time-varying characteristics of ambient sounds. In fact, ambient noise having exactly an NC spectrum is likely to be described as both rumbly and hissy, and will probably cause some annoyance. — Toole, Floyd E, Sound reproduction- the acoustics and…, 937
