When a child strains to follow instructions, confuses words that have very similar sounds, or seems distracted in loud places, parents may wonder if hearing loss is the problem. However, in some circumstances, the problem may not lie with the ears themselves, but rather with a condition called auditory processing disorder (APD), which affects the way the brain deals with sound.
Even though hearing loss and Auditory Processing Disorder (APD) frequently present with similar signs, they are distinct conditions that necessitate unique analyses and treatments. In this article, we will explore the key distinctions to help you give your child the support they need.
Comprehending Hearing Impairment: A Definition.
Impaired auditory function, also called hearing loss, occurs when a person’s capacity to sense sound is diminished, frequently caused by problems impacting 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 accumulation)
- 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 issues
Doctors normally diagnose patients by conducting tests such as audiograms, auditory brainstem response testing (ABR), and acoustic emission testing. If a child has hearing loss, the problem lies in their ability to detect sound to begin with.
What Is Auditory Processing Disorder?
In contrast, APD is not related to hearing problems, but rather a neurological issue that impacts the brain’s ability to process and understand auditory information. Kids with APD can hear just fine, but they have trouble making sense of what they hear.
It’s often described as “hearing but not understanding.”
Typical challenges faced in everyday situations:
- Difficulty understanding and executing verbal instructions consisting of multiple steps
- Struggling to distinguish between similar sounds or words
- Struggling in loud environments (including classrooms or restaurants)
- Having trouble recognizing humor, irony, or expressions that aren’t meant to be taken literally
Because the ears are working normally, a standard hearing test might come back showing no problems. However, it does not mean that everything is operating correctly. In APD, the breakdown occurs after sound is detected, during processing in the central auditory nervous system.
How Testing and Diagnosis Differ
To diagnose hearing loss, audiologists use conventional hearing exams that measure sound detection. Identifying Auditory Processing Disorder involves more in-depth assessments that extend beyond basic hearing evaluations.
Evaluations frequently involve a multidisciplinary team, including:
- A hearing specialist to assess how the brain senses sound
- A specialist in speech and language to assess understanding and expression skills
- 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 typically involves:
- Speech-language therapy
- Classroom accommodations (e.g., seating changes, written directions)
- Environmental modifications to reduce background noise
- Auditory processing therapy
Some Final Thoughts About Hearing Loss vs. APD
It’s essential to distinguish between hearing loss and auditory processing disorder in order to provide your child with the most effective assistance and accommodations. If your child appears to have trouble with listening in spite of having a normal hearing test, continue to explore further. A deeper look at how they process sound could expose what’s really going on. Children with the appropriate diagnosis and customized treatment strategy can excel academically, in their home environment, and in a variety of other aspects of their lives.
