What's the sound we can be hear at 1:10 please? I have hear a similar noise in my travel with a Airbus A319 in the pushback, before the starting up of the engines.
The sound is from the Power Tranfer Unit which produces a distinctive dog barking sound.The PTU is a reversible motor-pump located between the Green and Yellow hydraulic systems. It enables the green system to pressurize the yellow system, and vice versa, without fluid transfer.

Gonna be really sad when JM A321 leaves the fleet later this year to be replaced with B757. A321's are such quiet aircrafts.

They keep talkin about it but they're not gone as yet.

it should be the other way around because the A321 is also newer than the 757 overall
