The buzzsaw sound is a well-known feature of modern turbofan engines like those on the Airbus A320, created when the fan tips approach supersonic speed at high thrust and heard most clearly during takeoff. Aviation fans and plane spotters have long shared recordings of it online, and editors now use the effect to make travel videos, flight simulations and airport scenes feel authentic. Its appeal comes from that realism: listeners recognise the exact tone of a departing jet without needing any picture to explain it.
