White noise refers to a period of sound in the frequency component of the power in the entire audible range (0 ~ 20KHZ) are uniform, simply put, is the frequency of uniform sound, such as fan sound, hair dryer sound, vacuum cleaner sound, the sound of the waves, rain, radio no signal sound, etc.. The reason why babies like white noise is because it sounds similar to the mother’s heartbeat, mother’s intestinal peristalsis, and umbilical cord blood flow sound heard by the baby in the tummy, and the baby will calm down faster after listening to it and feeling back in the womb. The International Professional Sleep Organization mentions that white noise can be used as a method of putting babies to sleep when they are first born, listed in the 5s method of putting them to sleep. However, it is not encouraged as the only way to settle down to sleep and needs to be gradually replaced by other methods. Proper white noise relaxes the brain, and it is also very detrimental for babies to live in a silent environment. Too much reliance on white noise is not good for infants. 1, is not conducive to auditory development Noise in a broad sense is still a sound that makes the listener feel uncomfortable. Especially in favor of unpleasant, noisy, loud white noise, such as vacuum cleaners, motorcycle exhaust, aircraft takeoff. 2, improper use will be made into injury If the loudspeaker is too close to the baby’s ears, or adults are rushing to the baby’s ears “Sh” sound, easy to make the newborn frightened, injury to the eardrum. 3, is not conducive to the establishment of emotions Although it can temporarily quiet the baby, but can not meet the baby’s emotional needs. This method is often used to stop crying, which will make the baby insecure. 4. It is not conducive to the establishment of other soothing methods Over time, babies will form the habit of stopping crying only when they hear white noise and rely on white noise to help them sleep. Suggestions: Increase the amount of natural sound stimulation during the day to promote baby’s sensory development and reduce the dependence on white noise for sleeping. 1.Mother’s voice Babies will also feel warm and familiar with their mother’s voice. Humming to sleep can not only soothe the baby, but also build a good parent-child relationship. 2.Dad’s voice Dad’s voice is low, broad and raspy, and the baby responds positively to dad’s voice. The father-to-be should actively participate in the fetal education, and the baby will feel familiar with the father’s voice after birth and adapt to the new environment more quickly. 3.The sound of nature The white noise of nature is incomparable to the recorded white noise or wind turbine sound or mechanical noise. Take your baby outdoors to listen to the sounds of nature’s birds chirping, running water and falling leaves to stimulate the development of the senses. 4, listen to music reasonably Less high-tone high-frequency classical music and soft music. Music with low and medium frequencies is a gentle massage for baby’s eardrums, with rhythm, speed and beauty, laying the foundation for future learning.
