How does the prices of hearing differ between a person who is awake and a person who is asleep?

While you sleep, your brain continues to register and process sounds on a basic level. Noise can jostle your slumber—causing you to wake, move, shift between stages of sleep, or experience a change in heart rate and blood pressure—so briefly that you don't remember the next morning. Whether sounds disturb your sleep depends on factors such as the stage of sleep you're in, the time of night, and even your feelings about the sounds themselves.
