Paediatric Audiometry

How does paediatric audiometry work?

The methods used in paediatric audiometry vary depending on the age and developmental stage of the child. Here is how paediatric audiometry works:

• Objective testing methods: this methodis often used for infants and young children who cannot provide verbal feedback. This includes techniques like Auditory Brainstem Response (ABR) and Otoacoustic Emissions (OAE). ABR measures the electrical activity in the auditory nerve and brainstem in response to sound stimuli. OAE measures the sounds produced by the inner ear in response to external sounds.
• Behavioural testing: audiologists usually employ behavioural testing as children grow older and are better able to respond. Pure-tone audiometryinvolves presenting tones at different frequencies and intensities, and the child responds when they hear the sound. This is commonly used in older children who can participate actively.
• Play audiometry:this method turns the hearing test into a game, which makes it more engaging for young children. While utilising this method, the audiologist may ask the child to perform a simple task, such as placing a block in a bucket or putting a puzzle piece in a board, each time they hear a sound.
• Visual reinforcement audiometry (VRA):VRA uses visual stimuli, such as animated toys or lights, to reinforce the child's response to sound. The child is conditioned to associate the presentation of a visual reward with the perception of a sound.
• Diagnostic evaluations:paediatric audiologists may conduct detailed physical assessments to determine the type and degree of hearing loss, if present. This may involve assessing the function of the middle ear, inner ear, and auditory nerve through additional tests like tympanometry or acoustic reflex testing.
• Speech and language assessment:paediatric audiologists may collaborate with speech-language pathologists to assess speech and language development in children with hearing impairment.

It is essential to consider the child's developmental stage and choose appropriate testing methods to obtain accurate and reliable results. Paediatric audiometry aims to identify hearing issues early on, which can help plan timely intervention and support to promote optimal speech, language, and overall development in children with hearing challenges.

What conditions can paediatric audiometry diagnose?

Paediatric audiometry is a diagnostic tool used to assess and diagnose various hearing-related conditions in children. Some of the conditions that paediatric audiometry can help identify include:

• Otitis media:otitis media is a condition resulting in the inflammation of the middle ear, which is a common cause of temporary hearing loss in children.
• Sensorineural hearing loss:sensorineural hearing loss is caused by damage to the inner ear or auditory nerve, often permanent.
• Conductive hearing loss:in some cases, issues in the outer or middle ear that interfere with the transmission of sound to the inner ear can result in hearing issues among children.
• Speech and language delay:hearing impairment can impact speech and language development, and audiometry can help identify such delays.

It's important to note that while paediatric audiometry helps diagnose these conditions, the treatment plan would depend on the specific diagnosis. Treatment options may include medical interventions, such as hearing aids, cochlear implants, speech therapy, educational support, or a combination of these approaches.

What results can I expect from paediatric audiometry?

When you bring your child to D&S Audiology for audiometry evaluation, you can expect a thorough and child-friendly assessment of their hearing abilities. Our experienced audiologists will employ a combination of age-appropriate testing methods, such as play audiometry or visual reinforcement audiometry, to make the experience engaging and comfortable for your child.

The process begins with a detailed case history to understand risk factors or concerns. During the evaluation, the audiologist will carefully measure the child's response to various sounds and identify any signs of hearing impairment. The results will provide insights into your child's auditory health, which will help determine the root cause of their hearing issues.

If hearing impairment is identified, our team will guide you through the following steps and discuss appropriate treatments or further evaluations as needed. We aim to ensure a positive experience for you and your child while providing accurate information about their hearing capabilities.

How many audiometric assessment sessions are needed? 

The number of audiometric assessment sessions children need varies based on individual circumstances. Usually, an initial screening occurs shortly after birth to detect any immediate concerns. Subsequent assessments are often scheduled during key developmental stages, such as infancy, preschool, and school-age years. If risk factors or concerns arise, like delayed speech and language, additional evaluations may be recommended. Regular monitoring is crucial, as hearing abilities can change over time.

If you have concerns or doubts about hearing or balance issues in your child, please schedule an appointment with D&S Audiology for a detailed examination. Our audiologist will assess your child’s hearing health and recommend appropriate treatment.
