Air conditioner sound
An air conditioner vent humming. A low, steady drone.
A 2-minute recording played in random overlapping segments, the way the app plays it, so you won't hear a loop. Start with your volume low. Keep this tab open.
About this sound
An air conditioner vent humming in a quiet room: a low, steady drone of moving air, with no compressor cycling on and off.
We used a steady stretch of the original. The app plays 4 minutes of it as random stretches of about half a minute joined with 4-second crossfades, with no added volume drift, so it stays as flat as the real vent. The player on this page uses a 2-minute excerpt.
How people use it
People who sleep with the AC on in summer often miss the sound in winter or when travelling. It is low and even, so it covers traffic and household sounds well.
Keep it quiet and let it sit in the background. Rain on top makes it feel like a summer night with the window closed.
If you need more masking, brown noise underneath adds weight without adding hiss.
Questions
Does it click on and off like a real AC?
No. It is the steady hum only, without the compressor starting and stopping, so nothing changes during the night.
Is AC noise like brown noise?
It is similar: most of its energy is low and it has little hiss. It sounds more like a real room than generated noise does.
Why play an AC sound instead of running the AC?
You get the steady sound without the cold air, the running cost or the compressor switching on and off during the night.
