YVR wakes the dead

Just lying here hoping to quell the fluttery tired edge from travelling, eating, not sleeping, and it's impossible. For some reason announcements at this airport are at about 128db, virtually on the point of pain - I am wearing earplugs and it's like a very Loud Thing. Why? Are west coasters all deaf, or do they only plan to be that way?

Ps they only seem to do it when they feel like it - shouty bird II just came on then turned the local speakers off, I could hear the shouting elsewhere but not here (hear?!). They do have a horrible warbling pre-announcement tone too...
