Speaking about f-ed up sound...
I was playing Sunset Valley, the beachfront lot between the Wan-Goddard and the Ursine house lots. I hear a baby crying; no kid on my lot. More crying; I'm like wtf? I move over to the Ursine lot and behold, there is a crying baby whose cries could be heard in one lot over.
Then I hear a doorbell, look down and nobody is at the door. Again I go wtf...scroll to the neighboring lot and...you guessed it...someone was ringing the doorbell of the Wan house.
My sims moved out shortly after that. Although, the view is lovely, so I may just evict those idiots and put in a family with NO close neighbors
