Loudness and Masking Patterns of Narrow Noise Bands
The loudness of narrow noise bands of equal intensity at 8.5 kHz increases for bandwidths Δf ≦ 300 Hz. The masking pattern of a 10 Hz wide masker at 8.5 kHz is inferior to the masking pattern of an equally intense 1800 Hz wide masker at 8.5 kHz. The loudness differences are correlated to the different masking patterns of the narrow noise bands. Differences in the masking of test tones by narrow noise bands with different bandwidths at high centre frequencies can be estimated, when weighting the envelope fluctuations of the masker by backward- and forwardmasking functions.
