Does white noise actually help focus?

Yes. Studies show consistent background noise masks intermittent distracting sounds — conversations, traffic, barking dogs. The brain stops processing the consistent noise after minutes, but would keep reacting to random interruptions.

Where to place a white noise machine in an office?

Between you and the noise source — not right next to your ear. For home offices, place it near the door. For open offices, on your desk facing outward. 3-5 feet from your head is ideal.
