AFAIUI, being autistic can completely remove the ability for the brain to filter out certain types of stimuli. (Autism is a spectrum, but defective filtering of certain stimuli is a known autistic trait.) It might not necessarily be possible to train/practice dissociation like that.

I haven't tried it though, that sounds interesting. I would probably want to use headphones for it though, as otherwise, the volume required to actually bother me would probably fill the entire apartment complex ;D
