How can hearing loss affect my baby's language development?

Hearing loss. Hearing is the most important sensory function necessary for speech development. If an infant cannot hear, he/she likely may become a deaf mute. It is important the baby needs full otological evaluation to correct the hearing loss. The earlier the detection the better for the baby.
Definitely. Children learn to talk by hearing us speak. Depending on the severity of the hearing loss you can loose the ability to hear certain frequencies and by this parts of word can not be heard. Newborn screening programs are very helpful in detecting some children with hearing loss. The earliest it is detected, the better the outcome for learning good speech and language.
Negatively. If a baby has hearing loss they cannot hear some sounds well, particularly the quieter sounds of "s, " "sh, " "f, " "t, " and "k". This makes it harder for them to understand language and slows their own language development. The earlier and more severe the hearing loss, the more delayed their language may be.
It may be delayed. Hearing loss can have profound implications for baby's speech development. This is why newborn hearing screening programs are now carried out. Early identification of hearing loss leads to early intervention to correct hearing, and early speech therapy. Even infants with hearing loss can be taught sign language. If further hearing testing is recommended for your baby, be sure to follow-up.
Significant impact. Even mild hearing loss can impact speech and language development, both receptive (understanding what others say) and expressive (communicating words to others). Single sided hearing loss (one good and one deaf ear) puts a child at substantial risk of academic difficulties, with 1 in 3 failing a grade. It is vitally important to address hearing loss early, even as a baby if you can.
