When a child strains to follow instructions, confuses words that have very similar sounds, or seems distracted in noisy places, parents may wonder if hearing loss is the problem. However, in certain instances, the issue might not lie with the ears themselves, but instead with a condition known as auditory processing disorder (APD), which impacts the way the brain processes sound.
Even though hearing loss and Auditory Processing Disorder (APD) often present with comparable signs, they are distinct conditions that necessitate unique assessments and interventions. In this article, we will explore the fundamental distinctions to help you give your child the support they require.
What is Hearing Loss?
Hearing loss describes a reduced ability to detect sound, usually a result of issues in the outer, middle, or inner ear.
Three primary classifications:
- Conductive hearing loss: Triggered by obstructions or damage in the outer or middle ear (including ear infections or wax accumulation)
- Sensorineural hearing loss: Occurs when there is damage to the inner ear or the auditory nerve, which is typically triggered by factors including aging, exposure to loud noise, or genetic predisposition
- Combination hearing loss: A blend of both outer/middle ear and inner ear problems
Doctors normally diagnose patients by carrying out tests such as audiograms, auditory brainstem response testing (ABR), and acoustic emission testing. If a child suffers from hearing loss, the problem lies in their ability to detect sound to begin with.
What Does Auditory Processing Disorder Mean?
APD, on the other hand, is not a hearing problem; it’s a brain-based problem with interpreting sounds. Kids with APD can hear perfectly fine, but they have difficulty making sense of what they hear.
It’s commonly referred to as “perceiving sounds without grasping their meaning.”
Common obstacles faced in everyday situations:
- Trouble understanding and executing verbal instructions consisting of multiple steps
- Difficulty distinguishing similar sounds or words
- Struggling in noisy settings (like classrooms or restaurants)
- Misinterpreting jokes, sarcasm, or figurative language
A basic hearing test might indicate no issues because the ears are working normally. In APD, the malfunction occurs after sound is detected, during processing in the central auditory nervous system.
How Testing and Diagnosis Vary
Audiologists employ standard auditory assessments to identify hearing impairments by evaluating an individual’s ability to sense sound. 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 specialist in speech and language to assess understanding and expression skills
- A psychologist should be consulted to determine any underlying attention or learning conditions that might mimic the symptoms of Auditory Processing Disorder (APD)
Treatment and Support Options
If your child is diagnosed with hearing loss, treatment may include:
- Hearing aids
- Cochlear implants
- Assistive listening devices
- Medical or surgical interventions
Or, if your child is diagnosed with APD, assistance usually involves:
- 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 differentiate between hearing loss and auditory processing disorder in order to provide your child with the most reliable assistance and accommodations. If your child appears to have difficulty with listening despite having a normal hearing test, continue to explore further. A more detailed look at how they process sound could reveal what’s actually happening. With the correct diagnosis and tailored treatment plan, children with either condition can thrive in the classroom, at home, and beyond.
