If a child has difficulty comprehending directions, mixes up words with similar pronunciations, or appears disoriented in noisy surroundings, parents may presume that a hearing problem is to blame. But in some situations, the issue might not be with the ears at all: It could be a disorder called auditory processing disorder (APD).

Even though 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 break down the main differences to help you support your child’s unique needs.

What is Hearing Loss?

Impaired auditory function, also called hearing loss, happens when a person’s ability to perceive sound is diminished, frequently caused by problems impacting the outer, middle, or inner ear.

Three key classifications:

• Conductive hearing loss: Caused by obstructions or damage in the outer or middle ear (including ear infections or wax buildup)
• Sensorineural hearing loss: Occurs when there is damage to the inner ear or the auditory nerve, which is typically triggered by factors including aging, exposure to loud noise, or hereditary predisposition
• Mixed hearing loss: A mix of conductive and sensorineural types

Physicians usually make a diagnosis via standard hearing tests like audiograms, otoacoustic emissions, or auditory brainstem response (ABR) testing. If a child suffers from hearing loss, the issue lies in their ability to sense sound in the first place.

What Does Auditory Processing Disorder Mean?

In contrast, APD is not associated with hearing difficulties, but rather a neurological issue that affects the brain’s ability to process and comprehend auditory information. Kids with APD can hear just fine, but they have difficulty making sense of what they hear.
It’s frequently described as “hearing but not understanding.”

Typical challenges faced in everyday situations:

• Difficulty understanding and executing verbal directions involving multiple steps
• Struggling to distinguish between similar sounds or words
• Having difficulty focusing in loud settings (such as schools or busy eateries)
• Misunderstanding jokes, sarcasm, or figurative language

Because the ears work normally, a conventional hearing test may come back revealing no problems. However, it does not indicate that everything is operating properly. In APD, the malfunction happens after sound is detected, during processing in the central auditory nervous system.

Distinguishing Between Testing and Diagnosis

Audiologists employ conventional auditory evaluations to identify hearing impairments by assessing an individual’s ability to sense sound. Pinpointing Auditory Processing Disorder involves more extensive evaluations that go beyond basic hearing tests.

Evaluations frequently involve a multidisciplinary team, including:

• A hearing specialist to assess how the brain interprets sound
• A specialist in speech and language to assess understanding and expression skills
• A psychologist to rule out attention or learning differences that might look similar to APD

Options for Treatment and Assistance

If your child is diagnosed with hearing loss, treatment might include:

• Hearing aids
• Cochlear implants
• Assistive listening devices
• Medical or surgical interventions

Or, if your child is diagnosed with APD, assistance usually involves:

• 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

It’s important to differentiate between hearing loss and auditory processing disorder in order to provide your child with the most effective assistance and accommodations. If your child seems to struggle with listening but their hearing test is normal, don’t stop there. The real problem may only be identified by more in-depth evaluations. With the correct diagnosis and tailored treatment plan, children with either condition can do well in the classroom, at home, and beyond.
