You put earplugs in your ears, and then turn up the volume?

Isn't that sorta like holding the brakes whilst flooring the accelerator?
What, exactly, are you trying to accomplish?

Ive done it too, Jay..

When I fly alone, and others arent there who dont have/wont use
earplugs.. I sometimes do that.

Most noise suppression occurs in lower frequencies, both with ANR and
the passive devices.

Most Radio audio is in the middle frequencies.. So in effect you
suppress LOTS of loud low freq engine noise and suppress minimal
voice-spectrum sound.
