jakob, I’ve been to plenty of chasunahs where there are tables right near the speakers. But that’s not so relevant because the band cranks up the volume to ear-splitting levels for the dancing, which is usually near the speakers.
bplady, cotton balls are pretty useless. You need good-quality earplugs. I recommend the Flents Quiet Contour Foam earplugs.
Hoping for Brisk, how does he know in advance whether the band will be too loud?
