Ripple-noise pitch strength stays level-independent across a 40 dB range.

Evidence

Pitch strength of peaked ripple noise is almost independent of sound pressure level. Within a level range of 30 to 70 dB, pitch strength decreases only by about 10%. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 828
