I have an old "CHASE" LP no one probably knows about but, they were a loud, very loud group with a few trumpets etc.blasting. I used it to test puppies a few days old for deafness. Just the opening bars would have puppies howling. I knew they could hear.
I probably should have tested again after the first trial
, to see if that destroyed their hearing. But, hey, I'm fine - huh, could you repeat that???
