音の設計で参考にした研究と技術資料です。研究が扱った音・対象者・利用条件は、本アプリとは異なります。
ノイズとマスキング
周囲の音を目立ちにくくする可能性がありますが、睡眠改善の根拠は不確かです。連続ノイズで睡眠が妨げられた研究もあります。

集中と背景音
白・ピンクノイズの小さな利益は主にADHDや注意困難のある小児の課題研究によるものです。一般成人やブラウンノイズ、日常の仕事への効果は確立していません。

自然音
短時間のストレス回復を支持する研究がありますが、指標によって結果は異なります。本アプリの合成音の効果を確かめたものではありません。
音楽的要素と静寂
音楽には主観的な睡眠の質を改善する根拠があります。特定の和音やノイズとの相乗効果は未確立です。本アプリのイベント休止は、研究で用いた無音とは異なります。

音合成とゆらぎ
音づくりの参考資料です。1/fの音量変化や合成方法による睡眠・集中の改善を示すものではありません。

安全設計と個人差
乳児向け機器の音圧研究と、騒音への反応の個人差に関する研究です。成人に最適な音量や、本アプリの安全性を保証するものではありません。

これらは本アプリとは独立に行われた研究であり、本アプリによる効果を実証するものでも、研究者らが本アプリを推奨するものでもありません。本アプリは医療機器ではなく、診断・治療を目的としません。

Research and technical references consulted in sound design. The sounds, participants, and conditions studied differ from this app.
Noise and Masking
Noise may make surrounding sounds less noticeable, but evidence for better sleep is uncertain. Some studies found that continuous noise disrupted sleep.

Attention and Background Sound
Small benefits of white and pink noise mainly come from task studies in children with ADHD or attention difficulties. Benefits for adults in general, brown noise, or everyday work are unestablished.

Nature
Some studies support short-term stress recovery, but results vary by outcome. They did not test this app's synthesized sounds.
Musical Elements and Silence
Music has evidence for improving perceived sleep quality. Benefits of specific chords or synergy with noise are unestablished. Pausing this app's sound events differs from the silence used in studies.

- Jespersen KV, et al. (2022). Listening to music for insomnia in adults. Cochrane Database of Systematic Reviews, CD010459.
Sound Synthesis and Fluctuation
These are sound-design references. They do not establish sleep or attention benefits from 1/f volume changes or synthesis methods.

Safety and Individual Differences
These studies concern infant sound-machine levels and individual responses to noise. They do not establish an optimal volume for adults or guarantee this app's safety.

These studies were conducted independently of this app. They do not demonstrate this app's effects, nor do their authors endorse this app. This app is not a medical device and is not intended for diagnosis or treatment.
