Hearing is one of the most important senses that humans possess. It allows us to communicate, learn, and interact with the world around us. As a parent, you must be wondering when does a baby develop hearing? It’s a common question that most parents have, and rightfully so. The ability to hear is crucial for a baby’s development. In this article, we’ll explore when and how babies develop hearing.

The Development of the Ear
The development of the ear begins during the first few weeks of gestation. The ear is one of the first organs to develop in a fetus, and by week 20, the baby’s ears are fully formed. However, they are not yet functional. It’s not until around week 25 or 26 that the baby’s inner ear is fully developed, and the auditory system starts to function.

Although the ears are fully formed by week 20, the baby cannot yet hear. The amniotic fluid that surrounds the baby in the womb blocks most sounds from reaching the baby’s ears. However, some sounds can still penetrate the fluid, such as the mother’s heartbeat, voice, and other internal sounds.
Research has shown that babies can recognize their mother’s voice while still in the womb. They can also respond to music, singing, and other external sounds. Studies have found that playing music for babies in the womb can have a calming effect and promote their cognitive development.
Hearing After Birth
After birth, the baby’s ear is fully functional, and they can hear a wide range of sounds. Babies are born with a preference for their mother’s voice and can recognize it within hours of birth. They can also hear their own cries, other voices, and environmental sounds.
It’s important to note that babies are born with a limited ability to hear. They can hear sounds as low as 20 decibels, which is equivalent to a whisper. However, they cannot yet distinguish between different sounds or locate the source of the sound. These abilities develop over time as the baby’s brain processes and interprets the sounds they hear.
The Importance of Early Hearing Screening
Hearing is crucial for a baby’s language, cognitive, and social development. Undetected hearing loss can cause delays in these areas, which can have long-term consequences. That’s why early hearing screening is essential. The American Academy of Pediatrics recommends that all babies have a hearing screening before they leave the hospital.
If a baby fails the hearing screening, further testing will be done to determine if there is a hearing loss. Early intervention is key to preventing delays in language and cognitive development. If a hearing loss is detected, the baby can be fitted with hearing aids or cochlear implants, and speech therapy can be started as soon as possible.
Conclusion
In conclusion, a baby’s ability to hear starts to develop in the womb, but they cannot yet hear until around week 25 or 26. After birth, the baby’s ear is fully functional, and they can hear a wide range of sounds. Early hearing screening is essential to detect any hearing loss and prevent delays in language and cognitive development.

The signs of hearing loss in a baby include not responding to sounds, not turning their head towards sounds, and not babbling or making other vocalizations.
4. Can hearing loss be cured?
Most cases of hearing loss cannot be cured, but they can be managed with hearing aids or cochlear implants.
5. How can I promote my baby’s language development?
