Why In The World Does The Airbus A220 Sound Like A Whale?

Aviation enthusiasts can tell if it’s an Airbus A220 taking off just by the distinctive sound it makes. This howling sound is sometimes described as sounding something like a whale, and is indirectly related to its Pratt & Whitney PW1500G geared turbofan. Variants of the PW GTF also power the Embraer E-Jet E2 series and some of the Airbus A320neos, but those aircraft do not have the same degree of howling sound.
