Narrower noise bandwidth raises pitch strength while higher center frequency also raises it

Evidence

In this demonstration, you hear different noise bands with different pitch strength. First, three bands at 500 Hz centre frequency are played, with bandwidths increasing from 10 Hz, over 100 Hz to 500 Hz, leading to a decrease in pitch strength. After this, you hear three noises with a constant bandwidth of 100 Hz, centred at 250 Hz, 500 Hz, and 2000 Hz leading to an increase in pitch strength. — Professor Dr.-Ing.
