Why is the A320 so noisy?
Why is the A320 so noisy? It's called the PTU, or Power Transfer Unit. It's basically an extra hydraulic pump that assists the system as necessary, and also does a self-test during engine start. But, it's very loud and people don't like strange, loud noises on airplanes, so I understand how it can be disconcerting!
Is the A320 quieter than the 737?
However, because of the logarithmic scale used in reporting decibels, this means the Boeing is about 50% "louder" than the Embraer aircraft. Similarly, the 737 is 0.9 decibels louder than the A320, or about 10% "louder".
What is the failure rate of the Airbus A320?

Is A320 noisy?
What I do find noisy on A320 series aircraft are the brake fans. Sometimes used on taxi out, and almost always used on taxi in, they can be very very noisy.
Why are Airbus planes so loud?
It's the PTU that makes the barking noise. It transfers hydraulic pressure from one of the systems to the other when there is a measurable pressure difference, 500 psi. between the two. When the pressure drops, the PTU kicks in.
What is the quietest plane in the world?
