First and foremost, baby monitors work more efficiently between ground floor and first floor areas. However, if your home is made of thick concrete walls or has aluminum siding, then this can terribly decrease the strength of the transmitted signal. Instead, they receive muffled, indefinable, and sometimes almost inaudible sounds which resemble voices and words coming from a human.
