Widespread night-fears to the contrary, you could probably get away even without shielding unless the signals venture through heavy-duty magnetic fields (electrostatic fields are unlikely to be a problem, since capacitive coupling wiull be ineffective at low Z. Watch out for ground-loops or the like- there's the most likely source of corruption. Also beware RF interference (maybe you'd better use shielded cables after all!) :
