What all Items muffle your voice in Prox. chat?

I have been looking for about an hour now on youtube in here and on the wiki. i haven't found a single thing that lists what head wear muffles Prox. chat. I already know the Motorcycle helmet, and Gas masks do. Does anything else?

Gags muffle you too. From my experience the only things that muffle you are motorcycle helmets, gas masks and gags.
