Is Brown noise better than white noise?

As the video explains, white noise has ahigherfrequency and we perceive it to sound louder than itreallyis. Pink noise, which they play in the video, takesthisinto account and balances out the frequency. Brownnoise,which sounds like a low rumble or an ocean, lowers thehigherfrequencies even more.
