If a child has trouble understanding directions, mixes up words with similar pronunciations, or appears disoriented in loud surroundings, parents may suspect that a hearing problem is to blame. But in some cases, the issue might not be with the ears at all: It could be a condition called auditory processing disorder (APD).
Although hearing loss and Auditory Processing Disorder (APD) frequently present with similar signs, they are distinct conditions that require unique analyses and interventions. In this article, we will discover the fundamental distinctions to help you give your child the support they need.
What is Hearing Loss?
Impaired auditory function, also called hearing loss, happens when an individual’s ability to perceive sound is decreased, frequently caused by issues affecting the outer, middle, or inner ear.
There are three primary types:
- Conductive hearing loss: Occurs due to blockages or damage in the outer or middle ear, including ear infections or accumulation of earwax
- Sensorineural hearing loss: Involves damage to the inner ear or the auditory nerve, often caused by aging, noise exposure, or genetics
- Combination hearing loss: A blend of both outer/middle ear and inner ear issues
Doctors usually diagnose patients by carrying out examinations 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 in the first place.
What Is Auditory Processing Disorder?
In contrast, APD is not associated with hearing difficulties, but instead a neurological issue that affects the brain’s ability to process and comprehend auditory information. Children with Auditory Processing Disorder might have normal hearing, but they struggle to decipher and understand the sounds they hear.
It’s frequently described as “hearing but not understanding.”
Common challenges faced in everyday scenarios:
- Difficulty following multi-step verbal directions
- Difficulty differentiating similar sounds or words
- Struggling in noisy settings (like classrooms or restaurants)
- Having trouble understanding humor, irony, or expressions that aren’t meant to be taken literally
A basic hearing test may indicate no issues because the ears are working normally. But that doesn’t mean everything is functioning as it should. In APD, the breakdown happens after sound is detected, during processing in the central auditory nervous system.
Differentiating Between Testing and Diagnosis
To diagnose hearing loss, audiologists use conventional hearing tests that assess sound detection. Identifying Auditory Processing Disorder involves more extensive assessments that extend beyond standard hearing tests.
Multidisciplinary teams will typically include:
- A hearing specialist to assess how the brain interprets sound
- A speech-language pathologist to assess language comprehension and communication
- A psychologist should be consulted to determine any underlying attention or learning conditions that might imitate the symptoms of Auditory Processing Disorder (APD)
Approaches for Treatment and Assistance
Treatment options for children with hearing loss diagnosis:
- 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
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 reliable assistance and accommodations. If your child appears to have trouble with listening despite having a normal hearing test, continue to explore further. The real problem may only be identified by more in-depth assessments. With the right diagnosis and tailored treatment plan, children with either condition can thrive in the classroom, at home, and beyond.
