Hearing Loss Grading (WHO Classification)

Grades severity of hearing loss based on average hearing threshold (dB HL) per WHO classification. Guides audiological and surgical referral.

Score interpretation

Normal or mild loss (0-40 dB)

→ Reassurance; hearing aids if bothered by mild loss; annual review; treat reversible causes (wax, otitis media)

Moderate loss (41-60 dB)

→ Hearing aid fitting; audiological review; ENT assessment; consider middle ear surgery if conductive component

Severe to profound loss (>60 dB) or sudden

→ Urgent ENT (sudden loss <72h: emergency steroids); cochlear implant assessment for severe-profound; MRI IAM; speech and language therapy

Interpretation bands for the Hearing Loss Grade. Apply clinical judgement and local guidance.
