Simultaneous masking originates in the cochlea while nonsimultaneous masking does not

Evidence

It can be shown that simultaneous masking appears within the peripheral cochlear processes before the signals are transformed into neural information by the first synapses. Nonsimultaneous masking, however, was found not to be measurable within the peripheral process of the cochlea. For this reason, we can describe only simultaneous masking using cochlear models. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 650
