If a child has trouble understanding instructions, mixes up words with similar pronunciations, or appears disoriented in loud surroundings, parents might presume that a hearing issue is to blame. However, in certain circumstances, the issue might not be with the ears themselves, but instead 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 necessitate unique assessments and treatments. Below, we’ll analyze the main differences to help you support your child’s distinct requirements.
What is Hearing Loss?
Hearing loss refers to a reduced ability to detect sound, often a result of problems in the outer, middle, or inner ear.
There are three primary types:
- Conductive hearing loss: Caused by blockages 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 caused by factors including aging, exposure to loud noise, or genetic predisposition
- Mixed hearing loss: A combination of conductive and sensorineural types
Doctors normally diagnose patients by conducting tests such as audiograms, auditory brainstem response testing (ABR), and acoustic emission testing. If a child suffers from hearing loss, the issue lies in their ability to sense 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 issue with deciphering sounds. Kids with APD can hear just fine, but they have trouble making sense of what they hear.
It’s frequently described as “hearing but not understanding.”
Typical challenges faced in everyday situations:
- Difficulty understanding and carrying out verbal directions consisting of multiple steps
- Struggling to differentiate between similar sounds or words
- Having difficulty focusing in loud settings (such as schools or busy eateries)
- Misinterpreting jokes, sarcasm, or figurative language
A basic hearing exam may indicate no issues because the ears are functioning normally. However, it does not indicate that everything is operating properly. In Auditory Processing Disorder, the issue occurs not with hearing the sound itself, but instead with how the brain interprets and processes the sound after it has been sensed.
Distinguishing Between Testing and Diagnosis
In order to diagnose hearing loss, audiologists use traditional hearing tests that assess sound detection. Pinpointing Auditory Processing Disorder involves more extensive evaluations that extend beyond standard hearing evaluations.
Evaluations frequently involve a multidisciplinary team, including:
- A hearing specialist to evaluate how the brain senses sound
- A specialist in speech and language to evaluate understanding and expression skills
- A psychologist to rule out attention or learning differences that may look similar to APD
Options for Treatment and Assistance
Treatment approaches 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, assistance typically 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: Final Thoughts
It’s essential to distinguish between hearing loss and auditory processing disorder in order to provide your child with the most effective support and accommodations. If your child seems to have a hard time listening but their hearing test is normal, don’t stop there. A more detailed look at how they process sound could reveal what’s actually going on. Children with the appropriate diagnosis and personalized treatment strategy can succeed academically, in their home environment, and in various other aspects of their lives.
