最佳嬰兒助眠環境音
Finding the right background sound can transform your baby sleep experience. This activity engages your Infant Sleep Onset + Parental Sanity 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
white noise
The most studied sound for infant sleep. White noise mimics the broadband sound environment of the womb (blood flow, maternal heartbeat, digestive sounds). AAP recommends below 50 dB.
Recommended: 40-50 dBpink noise
Gentler than white noise due to reduced treble energy. For extended use (naps, overnight), pink noise is more comfortable for both baby and parent.
Recommended: 35-45 dBrain sounds
Natural sound with a pink-noise-like frequency distribution. Parents who find synthetic noise unpleasant often prefer rain as a more natural-sounding alternative.
Recommended: 35-45 dB立即試聽

專業建議
音量必須保持在50 dB以下——用手機App在寶寶耳朵高度測量。將音源放在距嬰兒床至少1公尺（3英尺）的地方，絕不要放在床內。使用定時器，不要在所有睡眠時段都持續播放。
常見問題
白噪音對嬰兒安全嗎？
在適當的音量（低於50 dB——大約安靜對話的音量）和距離（距嬰兒床1公尺以上）下，是安全的。AAP警告不要將大音量的白噪音機放在嬰兒床旁邊。在寶寶耳朵高度測量音量，而不是在設備處。使用定時器而不是整夜播放。
What does research say about sounds for baby sleep?
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 baby sleep?
For baby sleep, 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.
