When a child strains to follow instructions, mixes up words that have very similar sounds, or seems distracted in noisy setting, parents may wonder if hearing loss is the problem. However, in some instances, the issue might not lie with the ears themselves, but rather with a condition called auditory processing disorder (APD), which impacts the way the brain processes sound.
Even though hearing loss and Auditory Processing Disorder (APD) frequently present with comparable signs, they are distinct conditions that require unique assessments and treatments. Below, we’ll break down the main differences to help you support your child’s distinct requirements.
Comprehending Hearing Impairment: A Definition.
Hearing loss refers to a decreased ability to sense sound, often caused by issues in the outer, middle, or inner ear.
Three primary classifications:
- 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 triggered by factors such as aging, exposure to loud noise, or hereditary predisposition
- Combination hearing loss: A blend of both outer/middle ear and inner ear issues
Physicians typically make a diagnosis through standard hearing assessments like audiograms, otoacoustic emissions, or auditory brainstem response (ABR) testing. If a child has hearing loss, the problem lies in their ability to detect sound in the first place.
What Is Auditory Processing Disorder?
APD, on the other hand, is not a hearing problem; it’s a brain-based problem with interpreting sounds. Children with Auditory Processing Disorder may have normal hearing, but they struggle to interpret and understand the sounds they hear.
It’s frequently described as “hearing but not understanding.”
Some common challenges include:
- Trouble following multi-step verbal instructions
- Difficulty distinguishing similar sounds or words
- Struggling in noisy environments (like classrooms or restaurants)
- Misinterpreting jokes, sarcasm, or figurative language
Because the ears are working normally, a conventional hearing test may come back revealing no problems. But that doesn’t mean all is working as it should. In APD, the malfunction occurs after sound is sensed, during processing in the central auditory nervous system.
Differentiating Between Testing and Diagnosis
In order to diagnose hearing loss, audiologists use conventional hearing tests that assess sound detection. Diagnosing APD, on the other hand, calls for specialized testing that exceeds detecting sound.
Multidisciplinary teams will typically include:
- An audiologist to assess auditory processing abilities
- A speech-language pathologist to assess language comprehension and communication
- A psychologist should be consulted to identify any hidden attention or learning disorders that might 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
Support for Children with APD Diagnosis Typically Includes:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written instructions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
APD vs. Hearing Loss: Concluding Thoughts
It’s important to distinguish between hearing loss and auditory processing disorder in order to provide your child with the most effective assistance and accommodations. If your child appears to have difficulty with listening in spite of having a normal hearing test, continue to explore further. The real problem might only be pinpointed by more in-depth evaluations. Children with the proper diagnosis and personalized treatment strategy can succeed academically, in their home environment, and in various other aspects of their lives.
