Neutral Mid Noise — Compare the Mid-Band Texture
Neutral Mid Noise is a separately synthesized background sound designed for listeners who want an alternative to the familiar named noise colors. Its label describes an intended listening character, not a formally standardized spectral class.

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 Neutral Mid 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 Neutral Mid Noise sound like?
The overall measured spectral slope is relatively close to flat, but a single slope cannot fully describe the whole frequency response. The actual recording and its quantitative measurements, rather than the name alone, define this sound.
How it differs from related sounds
This is not interchangeable with our Green Noise: Green Noise has explicitly documented 165 Hz and 1,550 Hz filters, while this is an older independent DSP source with a different processing profile.
Five-band spectrum of Neutral Mid Noise
An independent band-shaped experiment, not an acoustics standard. 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 -2.76 dB per decade. Digital integrated level: -22.9 LUFS; true peak -12.9 dBTP. Neither proves a particular hearing-safe volume.
Understanding Neutral Mid Noise
Why a near-flat slope does not make this White Noise
The measured slope across 120–6,000 Hz is approximately −2.76 dB per decade, much closer to flat than several other variants. However, a single fitted line hides individual differences across frequency bands. This source was generated with its own mid-band-oriented filtering, including a stronger low-frequency high-pass stage around 680 Hz and upper filtering around 4,500 Hz. The per-band measurements below show what that combination actually produced.
“Neutral Mid Noise” is a site-specific name, not an internationally standardized spectral category. It does not mean that listeners should hear the entire midrange as equally loud, and it does not imply a specific medical or cognitive effect. This independent source may offer a different texture from ordinary White Noise despite superficially similar overall slope numbers.
Do not confuse it with Green Noise
Our separate Green Noise candidate has an explicitly declared 165 Hz high-pass and 1,550 Hz low-pass and is still awaiting listening approval. It is not a rename or an approved replacement for Neutral Mid Noise. Until the green candidate passes review, use the independently approved White, Pink or Blue files as reference comparisons; this page itself remains noindex pending a clearer standalone search intent.
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
Compare it with the defined Green and White masters to hear whether its balance is more comfortable in your room and on your playback system.

Questions about Neutral Mid Noise
Is Neutral Mid Noise a recognized acoustic standard?
No. It is a WhiteNoiseChoir descriptive name for this original DSP master.
Does it have the same band-pass filters as Green Noise?
No. Green Noise is a separate master with declared filter cutoffs. We do not attribute those settings to this file.
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 Neutral Mid Noise an official color of noise?
No. It is a descriptive WhiteNoiseChoir name for an independently rendered DSP master with its own band filtering. Its measured response matters more than the label.
Is Neutral Mid Noise a substitute for Green Noise?
No. The Green Noise candidate has different documented filters and is not yet approved for listening. The two files are distinct, and neither label is a universally standardized spectrum.
