If a child has trouble comprehending directions, mixes up words with similar pronunciations, or seems disoriented in loud environments, parents might presume that a hearing issue is to blame. However, in some instances, the problem may not be with the ears themselves, but rather with a condition called auditory processing disorder (APD), which impacts the way the brain deals with sound.
Although hearing loss and Auditory Processing Disorder (APD) often present with comparable signs, they are distinct conditions that require unique assessments and interventions. In this article, we will discover the fundamental differences to help you give your child the support they need.
What is Hearing Loss?
Impaired auditory function, also known as hearing loss, takes place when a person’s ability to perceive sound is decreased, often resulting from problems affecting the outer, middle, or inner ear.
There are three main kinds:
- 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 commonly caused by factors including aging, exposure to loud noise, or genetic predisposition
- Mixed hearing loss: A mix of conductive and sensorineural types
Physicians usually make a diagnosis via standard hearing assessments like audiograms, otoacoustic emissions, or auditory brainstem response (ABR) testing. When a child experiences hearing loss, the issue is with their capacity to perceive sound at all.
What Is Auditory Processing Disorder?
APD, conversely, is not a hearing issue; it’s a brain-based issue with interpreting sounds. Kids with APD can hear perfectly fine, but they have difficulty making sense of what they hear.
It’s frequently described as “hearing but not understanding.”
Some common challenges include:
- Difficulty following multi-step verbal instructions
- Difficulty distinguishing similar sounds or words
- Struggling in loud environments (including classrooms or restaurants)
- Having difficulty understanding humor, irony, or expressions that aren’t meant to be taken literally
A standard hearing test may reveal no problems because the ears are functioning normally. In Auditory Processing Disorder, the problem happens 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 tests that assess sound detection. Diagnosing APD, however, calls for specialized testing that exceeds detecting sound.
Multidisciplinary teams will usually include:
- An audiologist to assess auditory processing abilities
- A speech-language pathologist to assess language comprehension and communication
- A psychologist should be consulted to determine any hidden attention or learning conditions that might mimic the symptoms of Auditory Processing Disorder (APD)
Approaches for Treatment and Assistance
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 directions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
Some Concluding Thoughts About Hearing Loss vs. APD
It’s essential to differentiate between hearing loss and auditory processing disorder in order to provide your child with the most effective assistance and accommodations. If your child seems to struggle with listening but their hearing test is normal, don’t stop there. A deeper look at how they process sound could expose what’s really happening. With the correct diagnosis and tailored treatment plan, children with either condition can do well in the classroom, at home, and beyond.
