Hoping Bluetooth 5.2 with mass broadcasting features could be a solution. Some 5.2 hearing aids with voice pass through options to keep back ground music down, half the reason the music is so loud is they're old and going deaf anyway. With current tech, bunch of grandmas still need to sync up ipods like a flash mob which isn't going to happen. Add in spatial audio to simulate physical boom box. Apple get on this. As someone with ANC headphones all the time, personally very excited for when communal audio / seemless enviromental broadcast becomes a thing.
