White noise may help you if there is general room noise that needs to be masked. Its structure allows your brain to block out the disturbing sounds that keep you from concentrating or sleeping. This may be especially true for people who have issues with attentiveness and become especially distracted by noise. Try listening to a soft background noise of rain in a tropical rain forest or waves lapping on the beach. Those sounds would surely be relaxing and provide a uniform sound background.
