You have to wonder, are the flaps really much louder though, or is the A380 just extremely quiet, i remember reading an article about the pilots complaining that the A380 was too quiet and they couldnt get good quality rest because of noises they wouldnt normally hear during a flight.

I flew MAN-DXB and back a couple of weeks ago, outbound on an A380 and the return on the 77W, there is a massive difference in cabin noise between the two, the 777 of course being very noisy compared. I also did pickup on the noises as mentioned by the OP on approach in the 777 which sounded to me like a cargo door opening (it obviously wasn't). It sounded like there was a lot more going on even during taxi whereas with the 380 the only thing I heard of note was the flap retraction which was pretty loud, no doubt because of the sheer size and due to the requirements of the components moving them.

I was on a flight last week with my girl.  Airbus.  The PTU started going off, so I started barking like a dog.  She was confused and asked me multiple times to stop.  Did I?  Nope.  This flight was weird too.  The PTU was going on for at least a minute.  It got to the point where I started wondering about my sanity.  I was just sitting there, face pressed against the window barking with the PTU.  

 

That noise in the linked video is pretty cool though.  I hope we get it in wing view.  

I've always enjoyed the sounds of the cargo dog on the 'buses (the PTU).

 

Why?  Because it sounds like a dog.

I actually have a phobia of dogs (got attacked when little) - so it's not the nicest sound in the world. (Runs to the bathroom)

 

Airbus! Messing with Luke Pabari since 1995!!

Luke, is it THAT similar where you actually get a little anxious or is it because you've learned it's nickname?
