When a child struggles to follow instructions, confuses words that have similar sounds, or seems distracted in noisy places, parents might question if hearing loss is the problem. However, in certain circumstances, the problem may not be with the ears themselves, but instead with a condition called auditory processing disorder (APD), which impacts the way the brain processes sound.
Although hearing loss and Auditory Processing Disorder (APD) often present with comparable signs, they are distinct conditions that necessitate unique assessments and interventions. In this article, we will explore the key distinctions to help you give your child the support they require.
What is Hearing Loss?
Hearing loss refers to a decreased ability to sense sound, often caused by problems in the outer, middle, or inner ear.
There are three main types:
- Conductive hearing loss: Happens due to obstructions or injury in the outer or middle ear, such as ear infections or build-up of earwax
- 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 hereditary predisposition
- 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. When a child experiences hearing loss, the issue is with their ability to perceive sound at all.
What Does Auditory Processing Disorder Mean?
In contrast, APD is not related to hearing problems, but instead a neurological problem 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 interpret and comprehend the sounds they hear.
It’s often referred to as “perceiving sounds without grasping their meaning.”
Some common challenges include:
- Trouble following multi-step verbal directions
- Trouble distinguishing similar sounds or words
- Struggling in noisy environments (like classrooms or restaurants)
- Having difficulty understanding humor, irony, or expressions that aren’t meant to be taken literally
Because the ears work normally, a standard hearing test might come back showing no problems. However, it does not indicate that everything is operating correctly. 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 detected.
How Testing and Diagnosis Differ
Audiologists utilize standard auditory assessments to identify hearing impairments by evaluating an individual’s ability to sense sound. Diagnosing APD, on the other hand, calls for specialized testing that goes beyond detecting sound.
Evaluations frequently involve a multidisciplinary team, including:
- An audiologist to assess auditory processing capabilities
- 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 Options
Treatment options 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, support usually involves:
- 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
Understanding the difference between hearing loss and auditory processing disorder is essential for getting your child the right support. If your child seems to have a hard time listening but their hearing test is normal, don’t stop there. The real issue might only be identified by more in-depth evaluations. Children with the appropriate diagnosis and personalized treatment approach can excel academically, in their home environment, and in a variety of other aspects of their lives.
