Hearing loss analysis for children When and how is it done

Have you noticed that your child doesn't respond to sounds around them? Is their speech delayed compared to other children their age? You may need to consider a hearing delay test to identify the cause and take appropriate action.In this Dalili Medical article, we provide a comprehensive guide to the importance of hearing delay analysis, its types, how it's performed, and how to interpret the results.

What Is a Hearing Delay Test?

A hearing delay test is a set of hearing evaluations performed for children (and even adults) when there is a suspicion of hearing loss that may cause speech delay or communication difficulties. The goal is to determine whether the child has hearing impairment, and if so, identify its type and severity to plan the proper treatment.

Why Is Hearing Delay Testing Important?

Hearing is fundamental to the development of language and communication skills. When a child shows delays in response or speech, hearing loss may be the underlying cause. Early hearing tests help to:

Detect the problem as early as possible.
Start treatment at the right time.
Prevent long-term effects on speech, learning, and behavior.
Improve the child’s quality of life and support healthy development.

When Should a Hearing Delay Test Be Done?

It is recommended to perform the test in the following cases:

The infant does not respond to sounds during the first months.
The child does not say their first words by 12–18 months.
Noticeable speech or language delay.
Difficulty following instructions or responding to names.
Family history of hearing loss or genetic conditions.
The child was born prematurely or has frequent ear infections.

Types of Hearing Delay Tests

Hearing assessments vary depending on the child’s age and ability to cooperate. Common tests include:

1. Otoacoustic Emissions (OAE) Test

Used for newborns up to 6 months old.
Measures how the inner ear (cochlea) responds to sound.
Quick, painless, and non-invasive.
Indicates whether cochlear hair cells are functioning properly.

2. Auditory Brainstem Response (ABR) Test

Evaluates the auditory nerve and brainstem pathways.
Performed while the child is sleeping or under mild sedation.
Measures the brain’s electrical response to sound.
Accurately determines the degree of hearing loss.

3. Behavioral Audiometry

For children over one year old.
Observes the child's behavioral response to different sounds.
Uses lights or toys to engage the child during testing.

4. Pure Tone Audiometry

For older children and adults.
Determines how well a person hears various sound frequencies.
Measures both the type and severity of hearing loss.

5. Tympanometry

Measures the movement of the eardrum in response to pressure changes.
Helps detect fluid, infections, or blockages in the middle ear.

How Is the Hearing Delay Test Performed?

These tests are conducted in audiology clinics or hearing centers by certified audiologists. The steps include:

Collecting the child’s full medical history (birth, development, infections, family history).
Choosing the appropriate test based on the child's age and condition.
Performing the test in a quiet setting or while the child is asleep (especially for ABR).
Recording and analyzing the results to determine if there is a hearing delay and what type it is.

Understanding Hearing Test Results

Hearing loss is classified by its severity level:

Hearing Level	Hearing Loss (dB)	Impact
Normal	0–25 dB	No hearing problem
Mild	26–40 dB	Difficulty hearing soft sounds
Moderate	41–70 dB	Difficulty understanding normal speech
Severe	71–90 dB	Only hears loud sounds
Profound	90+ dB	Hears very loud sounds or none at all

What Happens After Diagnosis?

Once hearing delay is confirmed, the specialist will create a tailored treatment plan based on the type and severity of the hearing loss:

1. Hearing Aids

Used for children with mild to moderate hearing loss to amplify sounds.

2. Cochlear Implants

Recommended in cases of severe to profound hearing loss when hearing aids aren’t effective. They stimulate the auditory nerve directly.

3. Speech Therapy and Auditory Rehabilitation

Essential for improving speech, communication, and language skills—typically starts after hearing support is provided.

4. Medical or Surgical Treatment

For example, treating chronic ear infections or placing ventilation tubes to drain fluid from the middle ear.

The Importance of Early Hearing Screening

Studies show that intervention before 6 months of age leads to the best outcomes in:

Natural speech and language development.
Better social interaction and integration.
Closing the language and learning gap between the child and their peers.

Is Hearing Delay Testing for Adults Too?

Yes, adults may also need hearing tests if they experience:

Persistent ringing (tinnitus) or ear blockage.
Difficulty understanding speech, especially in noisy environments.
Needing to increase the volume of devices like TV or phone.

Tests like pure tone audiometry and auditory nerve assessments are used to find the cause.

Helpful Tips for Parents

Monitor your child’s speech and hearing milestones regularly.
Don’t delay testing if you notice warning signs.
Commit to therapy sessions and follow-up care.
Avoid exposing your child to loud noises or prolonged earphone use.

Conclusion

Hearing delay testing plays a vital role in diagnosing and treating auditory problems in children. Early detection and intervention can significantly improve your child’s speech, learning, and social development. If you suspect hearing issues, don’t hesitate—schedule a test and take the first step toward your child’s brighter future.
