"...perhaps most useful of all, Muffliato, a spell that filled the ears of anyone nearby with an unidentifiable buzzing, so that lengthy conversations could be held in class without being overheard."
— Use of the charm[src]

The Muffliato Charm (Muffliato) was a charm used to fill the ears of any person in the vicinity of the caster with an unidentifiable buzzing sound so as to allow for conversation without being overheard.[4]


An individual under the effects of this charm

The charm was invented by Severus Snape and recorded during his time as a student at Hogwarts School of Witchcraft and Wizardry, meaning it would have been created sometime between 1971 and 1978.[6][7] It is unknown when Severus Snape invented this and many of his other spells as according to Sirius Black "he knew more curses when he arrived at school than half the kids in seventh year".[8]

During the 1988–1989 school year at Hogwarts, this charm was taught by Professor Filius Flitwick to his fifth-year Charms students.[9]

Harry Potter used this spell multiple times during the 1996–1997 school year after discovering the Half-Blood Prince's copy of Advanced Potion-Making.[4] Hermione Granger originally disapproved of using the spell,[10] but came to use it herself when it was needed.[11][1]

On the 15 October, 1996, Ron Weasley suggested that Harry Potter should have cast Muffliato during Herbology class, to have prevented Professor Pomona Sprout from overhearing their conversation.[10]

On the 2 September, 1997, during the infiltration of the Ministry, Harry Potter realised that in the corridors near Dolores Umbridge's office was such silence as the Muffliato Charm was cast on the entire floor. He was also thinking about throwing Muffliato in the courtroom on Dolores Umbridge and Corban Yaxley, but he said that saying the incantation would cause a violent reaction from Hermione Granger.[12]
