Critical bandwidth stays constant with masker level up to about 50 dB.

Evidence

The location of the critical transition point in this experiment appears to be invariant with level, at least for a masker level up to about 50 dB. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 890

Above 500 Hz, critical-band rate grows logarithmically with frequency, roughly 20 percent per Bark.
BMLDs grow only slightly with masker density level and peak at intermediate bandwidths
Critical bandwidth at 2 kHz center frequency is 300 hertz
Critical bandwidth rises above 500 Hz, matching the 5-Bark reference point.
Fletcher's equal-power masking assumption is demonstrably false
