睡眠不好？记忆力衰退？最新研究表明，轻柔的“粉红噪音”可能有助解决这一问题。
Deep sleep is critical to maintaining a robust memory, but both decline with age.
深度睡眠对维持好的记忆力很重点，但无论是深度睡眠情况还是记忆力本身，都会伴随年龄的增长而出现衰退状况。
A small new study published inFrontiers in Human Neurosciencesuggests that one easy way for older adults to get deeper sleep and stronger memories is to listen to a certain soothing sound called “pink noise”—a mix of high and low frequencies that sounds more balanced and natural than its better-known cousin, “white noise.”
《人类神经科学前沿》期刊上发表的最新研究表明，老年人想要睡得更深和提升记忆力有个简单的办法，那就是听抚慰人心的“粉红噪音”。“粉红噪音”混合了高频和低频的声音，听上去比更出名的“白噪音”愈加和谐自然。
那样什么是粉红噪音呢？粉红噪音（pink noise）是自然界最容易见到的噪音，它主要分布在中低频段，瀑布声和小雨声都可称为粉红噪音。“粉红噪音”这名字起来自于这种噪声是介于白噪音与褐色噪音之间。
It may sound strange, but previous studies have found that playing so-called pink noise during sleep improves the memory of younger adults.
这听上去或许有的奇怪，但之前的研究发现，在睡眠时播放粉红噪音可以提升青年的记忆力。
