If a child has trouble comprehending directions, mixes up words with similar pronunciations, or appears disoriented in noisy surroundings, parents might suspect that a hearing issue is to blame. But in some cases, the problem may not be with the ears at all: It could be a condition called auditory processing disorder (APD).
Even though hearing loss and Auditory Processing Disorder (APD) frequently present with comparable signs, they are distinct conditions that necessitate unique analyses and treatments. Below, we’ll break down the key differences to help you support your child’s unique requirements.
What is Hearing Loss?
Impaired auditory function, also called hearing loss, occurs when a person’s capacity to sense sound is diminished, often resulting from problems affecting the outer, middle, or inner ear.
Three key classifications:
- Conductive hearing loss: Happens as a result of blockages or damage in the outer or middle ear, including ear infections or build-up of earwax
- Sensorineural hearing loss: Consists of damage to the inner ear or the auditory nerve, often due to aging, noise exposure, or genetics
- Combination hearing loss: A mix of both outer/middle ear and inner ear problems
Doctors normally diagnose patients by carrying out examinations including audiograms, auditory brainstem response testing (ABR), and acoustic emission testing. If a child has 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 problem with interpreting sounds. Children with Auditory Processing Disorder might have normal hearing, but they struggle to decipher and comprehend the sounds they hear.
It’s often described as “hearing but not understanding.”
Common challenges faced in everyday situations:
- Trouble following multi-step verbal instructions
- Difficulty differentiating similar sounds or words
- Having difficulty focusing in noisy settings (such as schools or busy eateries)
- Misinterpreting jokes, sarcasm, or figurative language
A standard hearing exam may indicate no problems because the ears are functioning normally. But that doesn’t mean all is functioning as it should. In APD, the breakdown happens after sound is detected, during processing in the central auditory nervous system.
How Testing and Diagnosis Differ
In order to diagnose hearing loss, audiologists use traditional hearing tests that measure sound detection. Identifying Auditory Processing Disorder involves more in-depth evaluations that extend beyond basic hearing evaluations.
Evaluations frequently involve a multidisciplinary team, including:
- A hearing specialist to evaluate how the brain senses sound
- A speech-language pathologist to evaluate language comprehension and communication
- A psychologist to rule out attention or learning differences that may look similar to APD
Approaches for Treatment and Assistance
If your child is diagnosed with hearing loss, treatment might include:
- Hearing aids
- Cochlear implants
- Assistive listening devices
- Medical or surgical interventions
Or, if your child is diagnosed with APD, support typically involves:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written instructions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
Some Concluding Thoughts About Hearing Loss vs. APD
It’s important 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. The real issue might only be identified by more in-depth assessments. Children with the proper diagnosis and personalized treatment strategy can excel academically, in their home environment, and in various other aspects of their lives.
