Soft White Noise — A Softer White-Noise Hiss
Soft White Noise retains a broad hiss-like texture while reducing some upper-frequency emphasis compared with the standard White Noise master. It is a distinct ten-minute DSP file, not White Noise renamed.
Listen to Soft White Noise
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 Soft White Noise 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 Soft White Noise sound like?
The observed power-spectrum slope is moderately negative rather than flat. This filtered broadband balance gives the source a softer edge without making it equivalent to standard Pink Noise.
How it differs from related sounds
Traditional White Noise is close to flat per hertz; this softer variant tilts down somewhat toward treble, while Pink Noise follows a more established 1/f definition. Our measured slope is disclosed so the difference is not just a marketing label.
Five-band spectrum of Soft White Noise
A filtered broadband master, not a standardized noise color. This chart displays sampled decoded-signal amplitude density, grouped by frequency. Values come from our source QA measurement code; no frequency response is guessed from a color name.
Bars are relative to the strongest band of this track only, not calibrated SPL or loudness at your ears. Numeric dBFS values are for decoded source measurements, not decibels in the room. Audio was measured with 16,384-point Welch analysis across four sampled portions of the 10-minute master. The fitted 120–6,000 Hz spectral slope is -6.70 dB per decade. Digital integrated level: -23.7 LUFS; true peak -14.0 dBTP. Neither proves a particular hearing-safe volume.
Understanding Soft White Noise
How this sound is softened
This is not a separate acoustics standard called “soft white.” It is an independently synthesized broadband recording that uses additional filtering to reduce some of the stronger upper frequencies. The production DSP design includes a high-frequency roll-off around 4,200 Hz, and the actual decoded master measures approximately −6.70 dB per decade over 120–6,000 Hz. That figure describes this file, not a universal definition of Soft White Noise.
A theoretically flat White Noise reference carries equal power per hertz. This master is deliberately tilted and filtered, which can make its hiss feel less bright. However, it is not identical to textbook Pink Noise, which is conventionally around −10 dB per decade before additional playback filtering. Try them side by side instead of treating the labels as interchangeable.
Choosing between an even hiss and a quieter upper range
Start with a low volume through the device you will actually use. Softer treble may be more pleasant for some people, but a sound file's digital LUFS or filter cutoff is not a real-world sound-pressure measurement. The adult bedtime collection allows quick listening comparisons without asserting that one spectral curve guarantees better sleep. If you are listening around a baby or child, refer to our caregiver safety guidance rather than assuming any recording is pre-calibrated for infants.
For conventional spectral definitions, see IEEE's colored-noise overview and the American Academy of Audiology's listening-volume caution. These are references for the physical principles, not endorsements of the recording.
Choosing a listening situation
A reasonable first comparison for listeners who enjoy a steady hiss but find standard White Noise too sharp. Choose volume and duration by comfort, especially near children.

Questions about Soft White Noise
Is Soft White Noise an official scientific noise color?
No. It is a descriptive label for this independently filtered broadband master.
Is it identical to Pink Noise?
No. The full master has its own spectrum, digital level and source file. Compare directly to choose by ear.
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.
Is the Soft White Noise file just standard White Noise at lower volume?
No. It is an independent 600-second DSP render with a different frequency response, including a deliberate high-frequency roll-off. Simply lowering the output volume would not create that spectrum.
Why is this page separate from the White Noise reference?
It documents the specific measured filtering and provides a distinct playable sound. The site currently treats the standard White Noise page as the main search reference while this variant remains noindex.
