最佳睡眠環境音
Finding the right background sound can transform your sleeping experience. This activity engages your Sleep Onset + Sleep Maintenance cognitive systems, which respond best to specific types of ambient sound.
Research says: Pink noise during sleep extends deep sleep (slow-wave sleep) by 25% and improves next-day memory recall. Pink noise matches the brain's own sleep oscillation frequency, reinforcing the slow waves responsible for memory consolidation. A separate ICU study found pink noise reduced time to fall asleep by 40%.

推薦聲音
rain sounds
The most universally effective sleep sound. Pink noise spectrum, parasympathetic activation, evolutionary safety signal. ICU studies show 40% faster sleep onset.
Recommended: 40-50 dBpink noise
The strongest scientific evidence: 25% deeper sleep, improved memory consolidation (Northwestern).
Recommended: 35-45 dBbrown noise
The TikTok favourite. Deep, enveloping, warm. Excellent for masking urban noise. Evidence is anecdotal but user reports are overwhelmingly positive.
Recommended: 35-50 dB立即試聽

專業建議
使用定時器（45-90 分鐘）而非整夜播放。Basner et al.（2025, UPenn）發現 50 dB 的持續粉紅噪音會減少約 18 分鐘的 REM 睡眠。讓聲音幫你入睡，然後讓安靜接管。
常見問題
整夜聽聲音安全嗎？
音量是關鍵因素。50 dB 以下不會有聽力風險。不過最新研究表明持續噪音可能減少 REM 睡眠。定時器（45-90 分鐘加漸弱淡出）能讓你獲得入睡幫助，同時避免整夜暴露。
What does research say about sounds for sleeping?
Pink noise during sleep extends deep sleep (slow-wave sleep) by 25% and improves next-day memory recall. Pink noise matches the brain's own sleep oscillation frequency, reinforcing the slow waves responsible for memory consolidation. A separate ICU study found pink noise reduced time to fall asleep by 40%. (Papalambros et al., Northwestern University / Frontiers in Human Neuroscience, 2017)
What volume should I use for sleeping?
For sleeping, set your volume to 40-50 dB. This range is based on acoustic research — loud enough to mask distracting noise, quiet enough to avoid auditory fatigue during extended listening.
