I know its one of the amityville horror movies but there's so many of them I can't remember which one. All I remember is this teenage girl (think she had short blond hair if I remember correctly) and there was this hole in the floor that echoed anything you said and she was messing around with it and making funny noises so it would echo and it did in a deep voice.

Possibly Amityville 3-D. There is a glowing hole type thing in the basement, and a short blonde haired character (young Meg Ryan).
