a plumback you shouldn't hear anything at all, if anything you will hear a little woosh, a tiny one, which is just the noise from the air going from the BOV through the pipe and back into the turbo compressor inlet. The idea of a plumback BOV is to recycle the air that has already gone through the compressor, and put it back into the compressor, and make no noise in the process.
I think it's also the fact that the air has gone through the intercooler that the EPA doens't like when using an atmo BOV.
