Q宝宝睡前哭闹,可以听白噪音吗?我家宝宝4个月大,最近睡觉前闹得厉害,听说有一种白噪音,我能让宝宝听吗?李璞医生:白噪音,是指一段声音中的频率分量的功率在整个可听范围(0~20KHZ)内都是均匀的。因为人耳对高频较敏感,所以这种声音听上去是很吵耳的沙沙声,近似于电台FM频段空白处的声音。在一些西方国家,很多接受过白噪音治疗的人形容其听上去像下雨的声音,或者像海浪拍打岩石的声音,再或者像是风吹过树叶的沙沙声。你可 Q baby sleep before crying, you can listen to white noise?

Because the human ear is more sensitive to high frequencies, it sounds like a loud noise, similar to the sound in the blank space of the FM band of a radio station. In some western countries, many people who have been treated with white noise describe their sounds as if they were raining, or the sounds of waves rocking the waves, or the rustle of wind blowing through leaves. you can
