Hearing Impairment
Types and Levels of Hearing Impairment in Children
Hearing impairment is described by type — conductive (outer/middle ear), sensorineural (inner ear or nerve) and mixed — and by degree, from mild through moderate, severe and profound. It can affect one or both ears. Early identification through newborn screening and listening milestones means most children can be supported well.
When a parent first hears the words "hearing impairment," the next question is always: which kind, and how much? Here's the clear map.
In short
Hearing impairment is described in two ways: the type (where in the hearing pathway the difficulty sits) and the degree (how loud sounds need to be before a child can hear them). The main types are conductive (outer or middle ear), sensorineural (inner ear or hearing nerve), and mixed (a blend of both). The degree runs from mild through moderate, severe and profound. Hearing loss can affect one ear (unilateral) or both (bilateral) — and most types can be supported beautifully when picked up early.The types, simply
By where it sits:- Conductive — sound is blocked in the outer or middle ear (for example by fluid, frequent ear infections or wax). Often temporary and treatable.
- Sensorineural — the inner ear (cochlea) or hearing nerve carries sound less well. Usually permanent, and the most common type present from birth.
- Mixed — features of both conductive and sensorineural together.
By degree (how soft a sound a child can detect):
- Mild — quiet speech and distant voices are missed.
- Moderate — normal conversation is hard to follow without help.
- Severe — only very loud speech is heard.
- Profound — even very loud sounds may not be heard; visual and amplified support matter most.
Hearing also matters for talking: even a mild or one-sided loss can quietly slow speech and language, which is why early identification — through newborn screening and watching listening milestones — is so important.
When to check
India's newborn hearing screening, your child's responses to your voice, and listening milestones (startling to sound as a baby, turning to their name, babbling, first words) all give early clues. Any concern at any age, or a recent loss of words or attention to sound, deserves a prompt hearing check.The Pinnacle way

What to watch
Does your baby startle to loud sounds, turn to your voice, babble by around 6–9 months, respond to their name, and say first words by their second year? Watch for any loss of attention to sound or words at any age.
Try this at home
Talk and sing to your child face-to-face, close by, in a quiet room — and notice whether they respond to soft sounds from behind, not just loud ones they can feel or see.

Frequently asked
What is the difference between conductive and sensorineural hearing loss?
Conductive loss is a blockage in the outer or middle ear — such as fluid or infection — and is often temporary and treatable. Sensorineural loss involves the inner ear or hearing nerve, is usually permanent, and is the most common type present from birth. A child can have both together, called mixed hearing loss.
What do mild, moderate, severe and profound mean?
These describe the degree of hearing loss — how loud a sound must be before a child can detect it. Mild means quiet and distant speech is missed; moderate means normal conversation is hard without help; severe means only very loud speech is heard; and profound means even very loud sounds may not be heard, so visual and amplified support matter most.
Can hearing impairment affect just one ear?
Yes. Hearing loss can be unilateral (one ear) or bilateral (both ears). Even one-sided or mild loss can quietly affect speech, language and listening in noisy places like classrooms, which is why early identification and support are so valuable.
When should I get my child's hearing checked?
India's newborn hearing screening offers a first check soon after birth. Beyond that, see a clinician if your child does not startle to loud sounds as a baby, does not turn to their name, is slow to babble or talk, or seems to lose attention to sound or words at any age.
