It's not so much *stimulus* that's to be blocked as *arousal*. Some regular or highly-structured stimuli actually have a calming, relaxing, quieting or regularizing effect, the opposite of arousal...such as a mother's heartbeat and breathing, or white noise. Music has been used for centuries to help induce altered stated of conciousness, including meditative states. A regular stimulus can serve to mask random distractions in the external environment.
