What it sounds like
A low, constant hum with a faint airy rush on top, like a cooled room somewhere out of sight. The pitch sits low and the edges are soft. There is no melody, no beat and almost no change from one minute to the next. What you notice most is what is missing: no sharp sounds, no rhythm to follow, nothing that asks for attention.
When it helps
People reach for it when they work or study and want the room to feel even. It also suits shared apartments and offices, where it can sit under voices and footsteps. Some listeners keep it on through a long reading session. Others use it as a quiet backdrop for chores or for winding down at the end of a loud day.
What to pair it with
Layer it with brown noise if you want more weight underneath, or pink noise to smooth the top of the hum. A distant rain bed can soften the mechanical feel without adding any rhythm. The hum is the steady center, so the second sound goes underneath.
