It seems to vary with airports.
I was asked only at Grenchen, Switzerland, in 2004, and since I didn't know I had it, I had to pay another 30 quid or so.
Never been asked since. But then I have not been to many German airports. The big ones don't seem to care. Maybe they have a system where they look up the aircraft type and get the noise figure from that. I could never understand the point of a noise certificate.
