This is one of my favorite problems :) It's so easy to state to people and surprisingly wasn't solved in the 2 dimensional case until 1992!
I also like how unrealistic the "drumheads" proposed in the proof were: https://en.wikipedia.org/wiki/Hearing_the_shape_of_a_drum https://en.wikipedia.org/wiki/Hearing_the_shape_of_a_drum

Of course, the head was ancient, as the creator had (IIRC) REMO put their heads on the hoops that he custom bent and sent to them. Sounded different than a normal drum. Was pink sparkle coated, so perhaps that had something to do with it :) The drum kit is still in the shop to this day (crazy old guy wants far too much for anything in the shop, as it has been there for an eternity, and well, all old is expensive, right?) I think about that set every now and then, as I myself was interested at one time.
