When a child struggles to follow instructions, mixes up words that have similar sounds, or seems distracted in loud setting, parents may question if hearing loss is the issue. However, in some instances, the problem might not be with the ears themselves, but instead with a condition called auditory processing disorder (APD), which impacts the way the brain processes sound.
Although hearing loss and Auditory Processing Disorder (APD) often present with comparable signs, they are distinct conditions that necessitate unique assessments and treatments. In this article, we will discover the key differences to help you give your child the support they require.
Understanding Hearing Impairment: A Definition.
Impaired auditory function, also known as hearing loss, takes place when a person’s ability to sense sound is diminished, frequently caused by problems affecting the outer, middle, or inner ear.
There are three primary types:
- Conductive hearing loss: Happens as a result of obstructions or injury in the outer or middle ear, including ear infections or accumulation of earwax
- Sensorineural hearing loss: Involves damage to the inner ear or the auditory nerve, often due to aging, noise exposure, or genetics
- Combination hearing loss: A mix of both outer/middle ear and inner ear issues
Physicians usually make a diagnosis via conventional hearing assessments like audiograms, otoacoustic emissions, or auditory brainstem response (ABR) testing. When a child experiences hearing loss, the issue is with their ability to perceive sound at all.
What Does Auditory Processing Disorder Mean?
APD, on the other hand, is not a hearing problem; it’s a brain-based issue with interpreting sounds. Children with Auditory Processing Disorder may have normal hearing, but they struggle to interpret and comprehend the sounds they hear.
It’s often described as “hearing but not understanding.”
Common obstacles faced in everyday situations:
- Trouble following multi-step verbal directions
- Difficulty differentiating similar sounds or words
- Having difficulty concentrating in noisy settings (such as schools or busy eateries)
- Having trouble recognizing humor, irony, or expressions that aren’t meant to be taken literally
A basic hearing exam might indicate no issues because the ears are working normally. In Auditory Processing Disorder, the issue occurs not with hearing the sound itself, but rather with how the brain interprets and processes the sound after it has been sensed.
Differentiating Between Testing and Diagnosis
Audiologists employ standard auditory assessments to detect hearing impairments by evaluating an individual’s ability to perceive sound. Identifying Auditory Processing Disorder involves more extensive assessments that go beyond standard hearing evaluations.
Evaluations often involve a multidisciplinary team, including:
- A hearing specialist to assess how the brain senses sound
- A speech-language pathologist to evaluate language comprehension and communication
- A psychologist to rule out attention or learning differences that may appear similar to APD
Approaches for Treatment and Assistance
If your child is diagnosed with hearing loss, treatment might include:
- Hearing aids
- Cochlear implants
- Assistive listening devices
- Medical or surgical interventions
Support for Children with APD Diagnosis Usually Includes:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written instructions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
Some Final Thoughts About Hearing Loss vs. APD
Understanding the difference between hearing loss and auditory processing disorder is crucial for getting your child the right support. If your child appears to have difficulty with listening in spite of having a normal hearing test, continue to explore further. The real issue may only be identified by more in-depth assessments. With the right diagnosis and individualized treatment plan, children with either condition can do well in the classroom, at home, and beyond.
