If a child has trouble understanding instructions, mixes up words with similar enunciations, or seems disoriented in loud environments, parents might suspect that a hearing problem is to blame. However, in some circumstances, the problem might 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) frequently present with similar signs, they are distinct conditions that necessitate unique assessments and treatments. In this article, we will explore the fundamental differences to help you give your child the support they need.
What is Hearing Loss?
Hearing loss describes a reduced ability to sense sound, often a result of problems in the outer, middle, or inner ear.
Three primary classifications:
- Conductive hearing loss: Happens due to blockages or injury in the outer or middle ear, including ear infections or build-up of earwax
- Sensorineural hearing loss: Happens when there is damage to the inner ear or the auditory nerve, which is typically caused by factors such as aging, exposure to loud noise, or genetic predisposition
- Combination hearing loss: A blend of both outer/middle ear and inner ear issues
Doctors normally diagnose patients by conducting examinations 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, conversely, is not a hearing problem; it’s a brain-based issue with interpreting sounds. Kids with APD can hear perfectly fine, but they have trouble making sense of what they hear.
It’s often referred to as “perceiving sounds without grasping their meaning.”
Some common challenges include:
- Trouble understanding and executing verbal instructions involving numerous steps
- Struggling to differentiate between similar sounds or words
- Struggling in noisy environments (including classrooms or restaurants)
- Misunderstanding jokes, sarcasm, or figurative language
A standard hearing test might reveal no problems because the ears are functioning normally. But that doesn’t mean all is working as it should. In Auditory Processing Disorder, the issue happens not with hearing the sound itself, but rather with how the brain interprets and processes the sound after it has been detected.
How Testing and Diagnosis Vary
In order to diagnose hearing loss, audiologists use traditional hearing tests that measure sound detection. Diagnosing APD, however, calls for specialized testing that exceeds detecting sound.
Evaluations frequently involve a multidisciplinary team, including:
- A hearing specialist to evaluate how the brain interprets sound
- A speech-language pathologist to assess language comprehension and communication
- A psychologist should be consulted to determine any hidden attention or learning conditions that may mimic the symptoms of Auditory Processing Disorder (APD)
Treatment and Support Solutions
If your child is diagnosed with hearing loss, treatment may include:
- Hearing aids
- Cochlear implants
- Assistive listening devices
- Medical or surgical interventions
Support for Children with APD Diagnosis Usually Includes:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written directions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
APD vs. Hearing Loss: Concluding Thoughts
It’s essential to differentiate between hearing loss and auditory processing disorder in order to provide your child with the most reliable support 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 reveal what’s actually going on. With the right diagnosis and individualized treatment plan, kids with either condition can thrive in the classroom, at home, and beyond.
