What noise annoys an oyster?

VERY LOUD AT WORK TODAY TO MUCH NOISE whoops sorry still shouting but it been a shouty,banging,crashing,AARRRRGH kind of a day and it's nice to be home to some peace and quite. One machine lifts floor tiles,lino,anything stuck to the floor but seem to shake the whole building, just glad I'm not operating it.
Started to snow late afternoon but it didn't come to much, just a light dusting on the ground so didn't bother blipping,might be more tomorrow so might get a pic then.
