Even very steep low-pass noise slopes produce pitch far weaker than a pure tone.
Evidence
As shown in Fig. 5.25, low-pass noise (sound 8) with extremely steep spectral slopes produces a pitch strength about 5 to 10 times smaller than the pitch strength of a pure tone, indicating a dependence On the steepness of the filter slope. — Professor Dr.-Ing.
