In the ICF, Auditory (code b230, Hearing functions) maps to the Body Functions component — Chapter 2, Sensory functions and pain. It describes the sensory functions of detecting and discriminating sound, and sits upstream of the Activities and Participation domains it enables, such as listening and communication. b230 is a foundational sensory function, distinct from its structural correlate (s260) and from higher auditory perception (b1560).

*Hearing is not just an ear function — in the ICF it is mapped as a distinct body function that underpins how a young child orients, listens and learns.*

## In short
In the **International Classification of Functioning, Disability and Health (ICF)**, *Auditory* — coded **b230, Hearing functions** — maps to the **Body Functions** component, specifically Chapter 2: *Sensory functions and pain*. It describes the sensory functions of sensing the presence of sounds and discriminating their location, pitch, loudness and quality. In early childhood, b230 sits upstream of the activity-and-participation domains it enables — listening, communication and social interaction — making it a foundational sensory function rather than an activity in itself.

## The science: where b230 sits and what it enables
The ICF separates *what a body system does* (Body Functions and Structures) from *what a person does* (Activities and Participation). **b230 Hearing functions** is a Body Function within the sensory chapter, distinct from its structural correlate **s260 (structure of the inner ear)** and from the higher-order processing captured under **b1560 (auditory perception)**. This matters in early-childhood profiling: a child may have intact peripheral hearing (b230) yet differences in auditory perception or in the *use* of hearing for listening and attending (mapped to Activities and Participation, e.g. **d115 listening**, **d310 communicating — receiving spoken messages**).

Framing auditory ability this way keeps assessment precise. It separates the sensory channel from the developmental skills it feeds — language, joint attention and social reciprocity — so that support can target the right level rather than conflating a hearing function with a communication outcome. For researchers and clinicians, b230 is therefore best read as the sensory *input* node in a functioning chain that extends into participation.

## When clinical referral matters
Because early auditory function underpins speech and language acquisition, any concern about a young child's responsiveness to sound — not orienting to voice, not startling, or delayed babble — warrants prompt audiological review alongside developmental assessment. The ICF domain mapping guides where to look, but confirmation of hearing status is a medical and audiological matter, not a therapy-first one.

## The Pinnacle way
This is general classification information, not a diagnosis — a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a [Pinnacle Blooms Network](/) centre, under qualified clinician care, through a clinician-administered structured assessment, never from an app or form. Where auditory function influences communication, our team links sensory profiling to targeted [speech therapy](https://www.pinnacleblooms.org/top-speech-therapy-center-india-proven-improvement-rate) and listening-skill development within an individualised plan.

**Next step —** If you are profiling a young child's auditory ability against the ICF, book a developmental and audiological review to map sensory function through to listening and communication outcomes.
