How does she react if you squeak her favorite toy, cry "Squirrel!" or get out her food and begin preparing it when she is in another room? Does she immediately come running?
She may have hearing issues where the tone of some sounds is more easily heard than others. It could be congenital but also could be from a small cyst on the nerve or inside the ear or a partially perforated ear drum, unusual growth of hairs or things in the ear canal(s) wad of ear wax - or it could all be behavioral and she ignores what she wishes to ignore. I'd have the vet check her hearing and her ears and try to find if anything physical is behind this.
