When a child struggles to follow directions, confuses words that have similar sounds, or seems distracted in loud places, parents may question if hearing loss is the issue. However, in some circumstances, the problem may not lie with the ears themselves, but instead with a condition called auditory processing disorder (APD), which affects the way the brain deals with sound.
Even though hearing loss and Auditory Processing Disorder (APD) frequently present with similar signs, they are distinct conditions that require unique assessments and treatments. In this article, we will explore the fundamental distinctions to help you give your child the support they need.
What is Hearing Loss?
Impaired auditory function, also called hearing loss, happens when a person’s ability to perceive sound is diminished, often resulting from problems affecting the outer, middle, or inner ear.
There are three main types:
- Conductive hearing loss: Caused by blockages or damage in the outer or middle ear (like ear infections or wax buildup)
- Sensorineural hearing loss: Happens when there is damage to the inner ear or the auditory nerve, which is typically caused by variables including aging, exposure to loud noise, or hereditary predisposition
- Combination hearing loss: A blend of both outer/middle ear and inner ear issues
Physicians usually make a diagnosis through standard hearing tests like audiograms, otoacoustic emissions, or auditory brainstem response (ABR) testing. If a child suffers from hearing loss, the issue lies in their ability to detect sound in the first place.
What Is Auditory Processing Disorder?
In contrast, APD is not associated with hearing difficulties, but instead a neurological problem that affects the brain’s ability to process and comprehend auditory information. Kids with APD can hear just fine, but they have difficulty making sense of what they hear.
It’s commonly referred to as “perceiving sounds without grasping their meaning.”
Typical obstacles faced in everyday situations:
- Trouble following multi-step verbal instructions
- Struggling to differentiate between similar sounds or words
- Struggling in noisy settings (including classrooms or restaurants)
- Misunderstanding jokes, sarcasm, or figurative language
A standard hearing test might indicate no issues because the ears are working normally. In Auditory Processing Disorder, the problem occurs not with hearing the sound itself, but instead with how the brain translates and processes the sound after it has been detected.
Differentiating Between Testing and Diagnosis
In order to diagnose hearing loss, audiologists use traditional hearing exams that assess sound detection. Identifying Auditory Processing Disorder involves more in-depth evaluations that extend beyond basic hearing tests.
Evaluations frequently involve a multidisciplinary team, including:
- An audiologist to assess auditory processing abilities
- A speech-language pathologist to evaluate language comprehension and communication
- A psychologist should be consulted to determine any underlying attention or learning disorders that may imitate the symptoms of Auditory Processing Disorder (APD)
Treatment and Support Solutions
Treatment options for children with hearing loss diagnosis:
- Hearing aids
- Cochlear implants
- Assistive listening devices
- Medical or surgical interventions
Or, if your child is diagnosed with APD, support usually involves:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written instructions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
Some Concluding Thoughts About Hearing Loss vs. APD
Understanding the difference between hearing loss and auditory processing disorder is crucial for getting your child the best support. If your child seems to have a hard time listening but their hearing test is normal, don’t stop there. A deeper look at how they process sound could reveal what’s actually happening. Children with the appropriate diagnosis and customized treatment approach can succeed academically, in their home environment, and in various other aspects of their lives.
