Hearing Assessment (Children)

Behavioral Hearing Tests

This test is used to determine the nature of hearing loss: conductive, mixed, sensorineural and central loss. It also differentiates hearing loss severity into five main categories: mild, moderate, moderately-severe, severe and profound loss.

(a) Pure Tone Audiometry (PTA)

It can determine ear and frequency specific hearing thresholds in children from 5 years of age.

(b) Play Audiometry (PA)

It can determine ear and frequency specific hearing thresholds in young children from 3 years of age through playing games.

(c) Visual Reinforcement Audiometry (VRA)

It is a reliable method to evaluate the minimum response level in children from 7 months of age through head-turn response.

Immittance Audiometry (IA)

(a) Tympanometry

This test can evaluate eardrum mobility. It can also help to diagnose middle ear pathology, e.g. middle ear infection.

(b) Acoustic Reflex Threshold

This test is used to assess the function of reflex muscles in the middle ear. Middle ear muscles will contract in response to loud sound s in normal hearing person. It can also use d to cross-check audiometric results.

Otoacoustic Emissions (OAE)

This test is used to assess inner ear (cochlear) function and also help to rule out middle ear pathology. It also provides objective inference of hearing sensitivity.
