If a child has difficulty comprehending directions, mixes up words with similar pronunciations, or seems disoriented in loud environments, parents may 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 disorder called auditory processing disorder (APD).
Although hearing loss and Auditory Processing Disorder (APD) frequently present with similar signs, they are distinct conditions that necessitate unique assessments and interventions. Below, we’ll analyze the key differences to help you support your child’s unique requirements.
Understanding Hearing Loss: A Definition.
Impaired auditory function, also known as hearing loss, happens when a person’s capacity to sense sound is decreased, frequently caused by issues affecting the outer, middle, or inner ear.
There are three main kinds:
- Conductive hearing loss: Occurs due to obstructions or damage in the outer or middle ear, including ear infections or accumulation 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 blend of both outer/middle ear and inner ear problems
Physicians usually make a diagnosis via conventional hearing assessments like audiograms, otoacoustic emissions, or auditory brainstem response (ABR) testing. If a child has hearing loss, the issue lies in their ability to sense 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 understand auditory information. Kids with APD can hear perfectly fine, but they have difficulty making sense of what they hear.
It’s often described as “hearing but not understanding.”
Common obstacles faced in everyday scenarios:
- Difficulty following multi-step verbal instructions
- Struggling to differentiate between similar sounds or words
- Struggling in noisy environments (like classrooms or restaurants)
- Having difficulty recognizing humor, irony, or expressions that aren’t meant to be taken literally
Because the ears work normally, a conventional hearing test might come back showing no issues. In Auditory Processing Disorder, the problem happens not with hearing the sound itself, but instead with how the brain interprets and processes the sound after it has been detected.
How Testing and Diagnosis Differ
Audiologists utilize standard auditory assessments to identify hearing impairments by assessing an individual’s ability to sense sound. Diagnosing APD, however, requires specialized testing that goes beyond detecting sound.
Evaluations often involve a multidisciplinary team, including:
- A hearing specialist to assess how the brain interprets sound
- A specialist in speech and language to evaluate understanding and expression skills
- A psychologist to rule out attention or learning impairments that might appear similar to APD
Options 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 Typically Includes:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written instructions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
Some Final Thoughts About Hearing Loss vs. APD
Understanding the difference between hearing loss and auditory processing disorder is crucial for getting your child the best support. If your child appears to have difficulty with listening despite having a normal hearing test, continue to explore further. The real problem might only be identified by more in-depth assessments. Children with the proper diagnosis and customized treatment approach can succeed academically, in their home environment, and in various other aspects of their lives.
