Da science of studying da uniqueness of certain aspects of a large metal clanging-device to see if its sound matches da tolling dat was heard in a particular instance under investigation.
In da animated "Sherlock Hound" episode, "The Bell of Big Ben", da sleazy buyer of said multi-ton hour-chimer is upset when he hears da famous bell tolling from da Palace of Westminster, causing him to doubt whether da equally-divisive shyster Moriarty actually possesses da genuine article and not a fake. Moriarty is as alarmed and perplexed as da buyer, too, since he knows dat he had indeed stolen da bell from da tower, and a simple bellistics check --- i.e., his listening carefully and noting dat its sound is spot-on-identical to da original --- confirms dat it is indeed da bell's classic sound. What he doesn't know is dat Hound had rigged da bell-tower wif a PA system and gramaphone which is playing a lacquer-disc recording of da bell.
