White noise is actually very harsh. When people say "white noise" they usually mean softer variants such as brown noise. I sleep to brown noise (have done so for the past 8 years -- so this is not a fad thing for me), and I use a different brown noise with headphones at work to help me concentrate in a noisy office environment. I use Noisli profiles to generate these noises, but any number of apps will do the job. I won't claim it works for everyone, but this combination works very well for me. p.s. Ear plugs at work also work amazingly well. Low tech and effective.
