You can hear any noise it doesn't have to be just voices---I was actually creating new music in my head at one point----it wasn't particularly good but it was something I had never heard before. Personally the TV thing would probably be an improvement from voices---because its not telling you what to do. Watch out for other types of hallucinations too while most people hear things you can physically feel things, smell things and see things as well---these are less common and can sometimes indicate a medical problem like epilepsy---the docs may want an MRI or EEG to rule this out but a lot of that depends on whether he responds to the meds or not.
