Noise-type sounds have far weaker pitch strength than pure or complex tones.

Evidence

However, continuous variations in parameters of sounds may clearly influence their pitch strength. For example, amplitude modulation of pure tones with low modulation frequencies (4Hz) can reduce their pitch strength by some 10 to 20%. This decrease in pitch strength holds also true for AM-tones partially masked by broadband noise. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
