Desk Fan Sound — Synthetic Airflow Noise
This Desk Fan sound approximates the steady airflow and low motor-like background associated with a small desktop fan. It was generated digitally rather than recorded beside a physical appliance.

Press Play; nothing starts automatically. With JavaScript, the shared player keeps listening active across pages and gives access to Volume, Sleep Timer and Dark Screen. Native MP3 controls remain available without JavaScript.
This master passed automated source checks. The site owner has approved the current 10-minute audio master. Realism varies by listener; use a comfortable volume.
Compare Desk Fan — Synthetic with other sounds
Hear the actual, different audio files. Switching selections preserves the existing sleep-timer deadline; recordings are not automatically matched for loudness. Start at a low volume when changing tracks.

What does Desk Fan — Synthetic sound like?
The recording is an independent ten-minute DSP render with a low-frequency weighted sound floor. Its measured spectral tilt is reported below; the source is not an authentic fan make, model or speed.
How it differs from related sounds
For an actual fan recording, explore Box Fan. That source is a different, short CC0 field recording and has more genuine environmental detail, but its independent capture is much shorter than this DSP master.
Measured sound spectrum: Desk Fan (synthetic)
This chart is derived from the decoded approved master, not estimated from the sound name. The bands summarize signal-amplitude density in a four-region Welch analysis of the encoded audio. Each bar is normalized against the strongest band of this track only; it is not suitable for comparing absolute playback levels across tracks.
The fitted spectral slope over 120–6,000 Hz is -28.59 dB per decade. Integrated source level is -24.2 LUFS and measured true peak is -12.4 dBTP. These are decoded-source measurements, not calibrated SPL or loudness at your ears. Analysis uses four sampled 20-second regions of the 600-second master with 16,384-point Welch windows. The slope is a regression over a subset of frequencies, not a universal physical law for the sound label.
The mechanical character of this simulated desk fan
A tabletop fan typically combines airflow turbulence, motor vibration and some blade-related modulation. This track is an interpretation of that texture, not a recording of a fan operating in a room. Its generator shapes broadband noise, adds a quiet 112 Hz synthetic motor component with a harmonic, and applies gentle modulation. These are deliberate synthesis choices; they do not establish the blade speed, electrical frequency or acoustic output of any specific appliance.
In the approved decoded MP3, the 80–250 Hz and 250–750 Hz analysis bands are close in sampled level. The high-frequency end declines markedly above 5 kHz. This explains why the sound has a relatively soft, mechanical background rather than the bright hiss of the Shower simulation. The measured −28.59 dB-per-decade fit describes part of this file, not a general fan-noise formula.
The real Box Fan recording is preferable if you want genuine environmental artifacts and motor detail. That CC0 source contains 67.52 seconds of independent recording before repeat; this independently generated desk-fan master contains 600 seconds of distinct rendered material. Longer does not automatically mean more realistic. A useful comparison is to listen for small fluctuations in airflow, identifiable motor detail and how obvious the loop boundary feels.
The Airplane Cabin and Desk Fan masters share some broad-band spectral shape in our five-band screening, despite different synthesizer profiles. That screen is not a listener identity test. The two files include different tonal and modulation settings, but users should audition them before assuming they deliver sharply different experiences.
Choosing a steady work background
Use this track as a predictable background when reading or completing desk work, especially if you like fan-like ambience but have no fan switched on. The sound is not positioned as a productivity treatment. Check the level when using headphones: changing tracks can change perceived loudness even if the website volume slider stays in the same position.
What the A/B control actually compares
The controls above switch among separately stored tracks in the shared player. Desk Fan is synthetic; Box Fan is real and repeats its short approved field capture. Air Conditioner is a different DSP composition with a darker spectral balance, and Low Rumble is intentionally much more bass-concentrated. The player does not loudness-match these files or infer which source sounds closest to a real appliance.
When to choose the real recording instead
Choose Box Fan when authenticity matters more than the length of independent source material. Choose Desk Fan when you want an even, purpose-built fan-like texture without incidental room noise. Neither should be described as an actual desk-fan brand, speed setting or calibrated acoustic model.
The measurements come from this site's source-generation and QA code, with track-level values preserved in the DSP manifest. The figures help compare frequency emphasis; they do not substitute for a calibrated listening experiment or actual field recording.
Choosing a listening situation
Choose this source if you prefer consistent machine-like background sound while reading, working or relaxing. Do not expect the same blade modulation as a specific real-world desk fan.

Questions about Desk Fan — Synthetic
Was this sound recorded from a real desk fan?
No. It is an original synthesized fan-like approximation; the source label is deliberately transparent.
Why can a synthetic fan sound feel more even?
The DSP is not constrained by room reflections and incidental environmental sounds in a real field recording. Realism still requires subjective listening approval.
Does the sound stop after ten minutes?
No. Ten minutes describes the MP3 master; the player uses continuous HLS or MP3 looping until stopped, the timer expires, or your device interrupts playback. HLS repeats the master rather than creating additional independent audio.
Can this reproduce the sound of a particular fan model?
No. The tonal and airflow components are generated by code, with no measured make/model profile. A real recording remains the right choice for appliance-specific sound.
Why does the real Box Fan page mention a shorter duration?
That file has 67.52 seconds of independently recorded CC0 material and is looped during playback. This synthetic page uses a separate, independently rendered 600-second file; both can play beyond their source durations.
