That's the whole point RD.
There are now three incidents to aircraft in the last year or so that have shown expectations from work/training in sims are not reflected in real life when masks are donned.
Whether through equipment shortomings, poor/complex switchery or other reasons regarding realism in training the hard evidence is showing serious communications problems when it happens for real.
Don't care whether the smoke/fumes are organo-phosphates or you're running a 70's retro disco revival in the back, there are real life recorded problems where cockpit communications are simply not working when they're most needed.
