A320 noise change in descent at 1.8 Delta PSI
Hey guys,

I have noticed that in the descent there is a noise change at 1.8 delta PSI. (Cabin VS-300 and cabin alt 500 feet).
This sounds like a change to the air con air as if there is more air flow coming out of the vents. A slight rushing sound. I'm sure that it's not anything to do with the air cond but that's the only way I can describe it.
This happens every descent. Any ideas?
