当孩子的语言发展不如预期时，许多家长都会疑惑，这只是孩子**“说话比较迟”，还是可能存在其他问题。虽然语言发育迟缓可能由多种因素引起，但听力损失**是其中一个经常被忽视的因素。
孩子是通过聆听来学习说话的。如果无法清楚地听到语音，学习语言的过程就会变得更加困难。越早发现听力损失，就越有机会帮助孩子发展沟通能力，并充分发挥他们的潜能。
在这篇文章中，我们将为您介绍听力损失如何影响语言发展、家长需要留意的警示信号，以及为什么新生儿听力筛查和儿童听力检查非常重要。
听力损失会导致语言发育迟缓吗？
是的。听力损失是导致儿童语言和言语发育迟缓的主要医学原因之一。
孩子通过聆听周围的声音、词语以及日常生活中的各种声音来学习语言。即使是轻度听力损失，也可能让孩子难以清楚地听到某些语音。随着时间推移，这可能会影响：
- 语言发育
- 词汇量发展
- 语言理解能力
- 学习与学业表现
- 社交互动
- 自信心与行为
听力损失发生得越早，如果未及时干预，对语言和言语发展的影响可能越大。
听力如何影响语言发育
从出生开始，宝宝就会不断通过声音学习。
他们会聆听：
- 父母的声音
- 日常对话
- 音乐
- 环境声音
- 不同的语音模式
通过反复聆听这些声音，宝宝会逐渐学习词语是如何形成的，并最终开始说话。
如果听力下降——即使只是轻微的听力损失——大脑接收到的语音信息也可能不完整。因此，孩子可能会难以模仿声音或正确发音。
孩子可能存在听力损失的迹象
许多有听力损失的孩子看起来与其他孩子一样健康，因此这种情况很容易被忽视。
请留意以下迹象：
婴儿（0–12个月）
- 听到巨大的声音时没有惊吓反应
- 6个月大时仍不会转向声音来源
- 不会持续地咿呀学语
- 叫名字时没有反应
- 对日常生活中的声音似乎没有反应
幼儿（1–3岁）
- 语言发育迟缓
- 与同龄孩子相比，使用的词汇很少
- 经常说“啊？”或“什么？”
- 说话时会注视对方的嘴唇
- 将电视音量调得很大
- 只有面对面说话时才会回应
Preschool Children
- Unclear speech
- 无法理解或执行简单的指令
- Frequently misunderstands conversations
- Easily distracted
- Learning difficulties
- Complains that people are mumbling
Not every child with speech delay has hearing loss—but every child with speech delay should have their hearing evaluated.
Hearing Loss Can Be Present From Birth
Many parents assume they would notice if their baby couldn’t hear.
Unfortunately, this isn’t always true.
Some babies are born with hearing loss that is not immediately obvious. Others develop hearing loss during infancy due to:
- 耳部感染
- High fever
- Certain viral infections
- Genetic conditions
- Premature birth
- Jaundice requiring intensive treatment
- Exposure to certain medications
Because hearing loss is not always visible, newborn hearing screening is strongly recommended for every baby.
Why Newborn Hearing Screening Is So Important
Newborn hearing screening is a quick, safe, painless test performed shortly after birth.
Its purpose is to identify babies who may have hearing loss before speech delay develops.
Early detection allows intervention to begin during the most critical period of brain and language development.
Research consistently shows that children identified and treated before 6 months of age have significantly better language outcomes than those diagnosed later. This
Evidence forms the basis of the Joint Committee on Infant Hearing’s internationally recognised 1-3-6 Early Hearing Detection and Intervention (EHDI) guidelines, which recommend:
- Hearing screening by 1 month
- Diagnostic audiologic evaluation by 3 months
- Appropriate intervention by 6 months
My Baby Passed the Newborn Hearing Screening. Do They Still Need Hearing Tests?
Yes.
Passing newborn screening only means your baby’s hearing was normal at the time of testing.
Some children develop hearing loss later due to illness, recurrent ear infections, genetic conditions, or progressive hearing loss.
Parents should seek a hearing assessment if they notice:
- Delayed speech
- Poor response to sounds
- 频繁耳部感染
- 听力损失的家族史
- Concerns raised by teachers or childcare providers
What Happens During a Children’s Hearing Test?
At Soundlife Hearing, children’s hearing assessments are designed to be child-friendly, comfortable, and age-appropriate.
Depending on your child’s age, the assessment may include:
- Video otoscopy to examine the ear canal
- Tympanometry to assess middle ear function
- Behavioural hearing tests (Visual Reinforcement Audiometry or Conditioned Play Audiometry)
- Pure Tone Audiometry for older children
- 耳声发射（OAE）
- Auditory Brainstem Response (ABR) or Auditory Steady-State Response (ASSR) for babies or children who cannot complete behavioural testing
Our audiologists will explain the results clearly and recommend the most appropriate next steps.
What If My Child Has Hearing Loss?
A diagnosis of hearing loss does not mean your child cannot learn to speak.
With early intervention, many children develop excellent speech and language skills.
Treatment depends on the type and severity of hearing loss and may include:
- Medical treatment by an ENT specialist
- Monitoring of hearing
- Speech and language therapy
- Hearing aids
- Family communication strategies
- Regular hearing review
The key is early identification and timely intervention.
Can Hearing Aids Help Children with Speech Delay?
If hearing loss is contributing to your child’s speech delay, hearing aids can make a significant difference.
Modern pediatric hearing aids are designed specifically for children and can:
- Improve access to speech sounds
- Support speech and language development
- Enhance learning in school
- Improve social communication
- Increase confidence
Children who receive hearing aids early generally achieve better communication outcomes than those whose hearing loss is identified later.
When Should Parents Arrange a Hearing Test?
Arrange a hearing assessment if your child:
- Is not meeting speech milestones
- Has unclear speech
- Frequently asks people to repeat themselves
- Has recurrent ear infections
- Failed newborn hearing screening
- Has a family history of hearing loss
- Shows behavioural changes related to listening
- Has concerns raised by teachers or doctors
Trust your instincts. If you are worried about your child’s hearing, it is always worth having it checked.
Early Detection Changes Lives
Speech delay is not always caused by hearing loss—but hearing loss should never be ruled out without proper testing.
The earlier hearing problems are identified, the sooner children can receive the support they need to communicate, learn, and thrive.
If you have concerns about your child’s speech or hearing, don’t wait.
A comprehensive hearing assessment can provide answers and peace of mind.
