Uniform masking noise can substitute for threshold-in-quiet across all frequencies.

Evidence

If it could be shown that the effect described in Fig. 6.1 takes place not only at threshold in quiet but also at the threshold produced by uniform masking noise, then it would be possible to measure this effect over the whole frequency range of hearing. — Professor Dr.-Ing.

Delayed emissions are suppressed in proportion to the evoking burst's audibility
Digital noise can be shaped to hide where hearing is least sensitive
Frequency-domain coding using masking avoids transmitting masked sound information
Inner-ear blood-flow noise is adapted out because it never stops
Noise bandwidth below the critical band does not raise masked threshold.
Synthetic noises deviate from Gaussian masking when line counts or phases are poorly chosen
The hearing system groups frequency bands together when their level variation is similar
Uniform quantization noise requires about 60 dB signal-to-noise to stay masked
White masking noise affects consonant perception in time slices as short as 100 ms.
