This isn't just spin. Neuronal adaptation at many time scales to changes in auditory stimuli has been demonstrated in many areas of the brain (primary auditory cortex, medial geniculate nucleus of the thalamus, inferior colliculus, etc.) in several species (from mice to monkeys, just considering mammals). Whatever else your electronics may be doing, your brain is definitely "burning in."
