Could you hear this whole chorus a mile away?

Maddie Coles

Abstract


Dolores Madrigal from the Disney musical Encanto has super-hearing and can hear her cousin Mirabel singing from a mile away. This paper explores the strength of this ability by calculating her threshold for hearing, -5.05 dB, and comparing it to the normal threshold for human hearing, 0 dB. If an average human were to hear this same song from a mile away, Mirabel would need to sing at a loudness of 125.05 dB, which is much louder than the typical human voice of 60 dB.
