# Types and Levels of Hearing Impairment

Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited

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
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under qualified clinician care — never from an app or an online form. From there your family gets a clear baseline and a plan, with [audiology and speech support](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) shaped around your child. Learn more about [hearing and listening development](/hearing) and how [your child's starting point is measured](/ask/what-is-the-abilityscore-and-how-is-it-calculated).

## Trusted sources
WHO ICD-11 classification of hearing loss; CDC developmental and hearing milestones; American Academy of Pediatrics guidance on newborn hearing screening; Indian Academy of Pediatrics.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
