Answer 1

EVPs from dead people!!! AHHHH!!!

Answer 2

It has something to do with the movie, something only children can hear. In the movie, only the children of the family can see and hear the spirits. There's a ringtone from the movie that only children can hear. It's wierd. But I didn't hear the sounds from the commercial (hint). 0_0
