01 Seeking Sound Sources
Newborns should have undergone hearing screenings shortly after birth. Infants with normal hearing will be highly attentive to human voices in the first month, especially to higher-pitched "baby talk." When you speak to them, they will turn their heads to find you and carefully listen to the different syllables and words you utter. If you observe closely, you may even notice their arms and legs making slight movements in response to your speech.
02 Sensitivity to Noise
Newborns are also sensitive to various levels of noise. If you produce loud tapping sounds near their ears or bring them into a crowded, noisy room, they may become startled, seemingly unresponsive as if they haven't heard anything; or they may exhibit extreme sensitivity, suddenly crying and struggling to move away from the noise. However, if they hear gentle rattling or quiet music, they become alert and turn their heads to locate the source of these intriguing sounds.
03 Recognition of Familiar Sounds
Newborns not only have good hearing but also remember certain sounds. Research has shown that some mothers who loudly repeated a particular story during late pregnancy found that their babies seemed to recognize it after birth—they became quieter and appeared more engaged when the story was read to them again.
