Critical-band noise masking can be approximated by simple tone complexes

Evidence

Critical-band wide noise can be approximated by pure tones. Here a narrowband noise at 2 kHz is approximated by an increasing number of pure tones centered at 2 kHz. The lower slope of the masked threshold of the criticalband noise and the pure tones is shown in Fig. 4.11. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
