There have been many times when I have heard the sirens and then maybe a minute or 2 later I would hear the cars (of the firefighters - I assume) who were driving to the firehouse.
When I first moved up here the sirens bothered me too. I also believe that there was a time when the sirens would sound at noon everyday but I'm pretty sure that they don't do that anymore.
since then I have come not to mind the sirens because I know that the firehouse is sounding them for a very specific reason.
