That was the preview. Air Conditioner Hum plays all night in NoiseZ Plus.
What it sounds like
A smaller, closer unit than a wall-sized air conditioner: a soft, even hum with a little breathy air in it. It stays at one level, so your ear learns it quickly and stops tracking it. The tone is warm and rounded rather than whiny. There is nothing to follow, no ticking and no sweep, only a plain steady drone in the middle of the room.
When it helps
A natural fit for the hour before bed, when you want the room to settle into one even sound. It also works at a desk, where a flat hum can sit behind email, reading or writing. Light sleepers often choose a sound like this because it stays the same all night, so nothing changes to wake them.
What to pair it with
A soft drone sits well with slow ocean waves, which add a gentle, wide movement over the hum. Brown noise deepens the low end if the unit sounds thin on your speaker. For a drier room tone, pair it with a quiet fan. The pairing works quietly, below the hum itself.
