My apologies, I actually haven’t checked in in 8 hours. But yes, if and when it’s nogeiah l’maaseh, hopefully not for a very long time, Wolf should ask a rav.
Or he could extrapolate from what I was told some time ago when in aveilus: when I rode Jewish transport (on a longish trip) I was told I did not have to tell anyone I was in aveilus and to turn off the music. (In fact, it would not be fair to the tzibbur were I to inform them I was in aveilus.)
