Speak up for a lower volume. Loud sounds, even those of good music, adversely impacts hearing -- and too loud sounds can make it difficult to think and otherwise function, too.
Continuing exposure to loud sounds has prematurely impaired the hearing of far too many.
One should be able to hear what a partner says in a normal voice when the music is playing. Otherwise the music's too loud.
Speak up. It's your hearing (and that of others) at risk. It's your thinking and functiong (and that of others) at risk.
And if the volume is not turned down to a satisfactory level? Fire the person/place. What does it mean to fire in this context? A core part of firing someone is that you no longer pay them. So, if the music continues too loud, cease hiring (paying money to) that person/place. Of course, tell them why you're firing them, nicely but clearly. Your money has power. If necessary, use it.
