@pschwahn@mathstodon.xyz am I missing something, or did they show only spectrograms and not actually include sound files of the isospectral drums :(

@pschwahn@mathstodon.xyz I thought there were simpler pairs found, no? Here's an (old) paper https://arxiv.org/abs/1005.1839 in which is also claimed that there are distinguished points in the domains that one need to strike, to be "homophonic". It's a pity NOT to make a video where we can hear the sounds!
