最佳婴儿助眠环境音
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%.

推荐声音
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立即试听

专业建议
音量必须保持在50 dB以下——用手机App在宝宝耳朵高度测量。将音源放在距婴儿床至少1米（3英尺）的地方，绝不要放在床内。使用定时器，不要在所有睡眠时段都持续播放。
常见问题
白噪音对婴儿安全吗？
在适当的音量（低于50 dB——大约安静对话的音量）和距离（距婴儿床1米以上）下，是安全的。AAP警告不要将大音量的白噪音机放在婴儿床旁边。在宝宝耳朵高度测量音量，而不是在设备处。使用定时器而不是整夜播放。
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.
