Its sound, measured. Press play to see it live.
A vacuum cleaner running steadily, with a door between you and it. The sound is a wide, even roar, bright at the top and thick in the middle. It is louder and more intense than a fan, but it does not stop or move around. The result is one flat, full wall of sound, with a clean, dry, mechanical character.
Many adults use it for naps and for masking, since a vacuum is a sound most people already know well. The broad roar covers speech and street noise with ease. It is a strong sound, so low volume is usually enough. Many people keep it for short rests instead of the whole night.
To take the harshness off the top, blend in brown noise. Pink noise sits between the two and makes a softer wall. A box fan alongside gives a rounder, airier version of the same idea. Tuck the extra layer under the vacuum and the combination stays smooth.
