When a child struggles to follow instructions, confuses words that have similar sounds, or seems distracted in loud places, parents may question if hearing loss is the problem. However, in certain circumstances, the issue might not lie with the ears themselves, but instead with a condition known as auditory processing disorder (APD), which impacts the way the brain deals with sound.
Even though hearing loss and Auditory Processing Disorder (APD) frequently present with comparable signs, they are distinct conditions that require unique assessments and treatments. Below, we’ll analyze the key differences to help you support your child’s unique needs.
Understanding Hearing Loss: A Definition.
Hearing loss describes a reduced ability to sense sound, usually caused by problems in the outer, middle, or inner ear.
There are three main types:
- Conductive hearing loss: Caused by obstructions or damage in the outer or middle ear (like ear infections or wax buildup)
- Sensorineural hearing loss: Involves 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 suffers from hearing loss, the problem lies in their ability to sense sound in the first place.
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 may have normal hearing, but they struggle to interpret and understand the sounds they hear.
It’s commonly referred to as “perceiving sounds without grasping their meaning.”
Some common challenges include:
- Difficulty understanding and executing verbal instructions involving multiple steps
- Difficulty distinguishing similar sounds or words
- Struggling in loud environments (like classrooms or restaurants)
- Misinterpreting jokes, sarcasm, or figurative language
Because the ears work normally, a conventional hearing test might come back revealing no issues. However, it does not mean that everything is operating properly. 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.
Distinguishing Between Testing and Diagnosis
Audiologists utilize standard auditory evaluations to identify hearing impairments by assessing an individual’s ability to perceive sound. Identifying Auditory Processing Disorder involves more in-depth assessments that go beyond basic hearing evaluations.
Evaluations often involve a multidisciplinary team, including:
- A hearing specialist to assess how the brain senses sound
- A speech-language pathologist to evaluate language comprehension and communication
- A psychologist to rule out attention or learning impairments that might look 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 Usually Includes:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written instructions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
APD vs. Hearing Loss: Final Thoughts
Understanding the distinction between hearing loss and auditory processing disorder is crucial for getting your child the right help. If your child appears to have trouble with listening in spite of 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 strategy can succeed academically, in their home environment, and in various other aspects of their lives.
