If a child has trouble understanding instructions, mixes up words with similar enunciations, or appears disoriented in loud environments, parents might suspect that a hearing issue is to blame. However, in certain circumstances, the issue may not be with the ears themselves, but instead with a condition known as auditory processing disorder (APD), which impacts the way the brain deals with sound.

Hearing loss and APD share several of the same symptoms, but they’re actually very different conditions that require specific assessments and support. Below, we’ll break down the key differences to help you support your child’s unique needs.

What is Hearing Loss?

Hearing loss refers to a decreased ability to detect sound, usually a result of problems in the outer, middle, or inner ear.

There are three main kinds:

• Conductive hearing loss: Happens due to blockages or injury in the outer or middle ear, including ear infections or build-up of earwax
• Sensorineural hearing loss: Happens when there is damage to the inner ear or the auditory nerve, which is commonly triggered by factors such as aging, exposure to loud noise, or genetic predisposition
• Combination hearing loss: A blend of both outer/middle ear and inner ear issues

Doctors normally diagnose patients by carrying out tests including audiograms, auditory brainstem response testing (ABR), and acoustic emission testing. When a child experiences hearing loss, the problem is with their capacity to perceive sound at all.

What Does Auditory Processing Disorder Mean?

APD, on the other hand, is not a hearing issue; it’s a brain-based problem with interpreting sounds. Children with Auditory Processing Disorder may have normal hearing, but they struggle to decipher and comprehend the sounds they hear.
It’s commonly referred to as “perceiving sounds without grasping their meaning.”

Some common challenges include:

• Trouble understanding and executing verbal instructions involving numerous steps
• Struggling to distinguish between similar sounds or words
• Having difficulty focusing in loud settings (such as schools or busy eateries)
• Having trouble understanding humor, irony, or expressions that aren’t meant to be taken literally

A basic hearing exam may reveal no issues because the ears are functioning normally. However, it does not mean that everything is operating correctly. In APD, the malfunction occurs after sound is detected, during processing in the central auditory nervous system.

Distinguishing Between Testing and Diagnosis

Audiologists utilize standard auditory evaluations to identify hearing impairments by evaluating an individual’s ability to sense sound. Pinpointing Auditory Processing Disorder involves more extensive assessments that extend beyond standard hearing tests.

Evaluations often involve a multidisciplinary team, including:

• An audiologist to evaluate auditory processing abilities
• A specialist in speech and language to evaluate understanding and expression skills
• A psychologist should be consulted to determine any underlying attention or learning disorders that may mimic the symptoms of Auditory Processing Disorder (APD)

Treatment and Support Solutions

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

• 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 directions)
• Environmental modifications to reduce background noise
• Auditory processing therapy

APD vs. Hearing Loss: Concluding Thoughts

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 despite having a normal hearing test, continue to explore further. The real problem may only be pinpointed by more in-depth assessments. With the correct diagnosis and individualized treatment plan, kids with either condition can do well in the classroom, at home, and beyond.
