Despite its prevalence, APD often goes undiagnosed or misunderstood, leaving many individuals struggling with daily communication and academic challenges.
This guide aims to shed light on the diagnosis and treatment of Auditory Processing Disorder. It will explore the nature of APD, discuss the steps involved in obtaining a proper diagnosis, and outline various treatment options available. By providing this information, the article seeks to help individuals, parents, and professionals better understand and address this often overlooked auditory condition.
Understanding Auditory Processing Disorder
Auditory Processing Disorder (APD), also known as Central Auditory Processing Disorder (CAPD), has an impact on how the brain interprets sound. It can significantly affect a person’s ability to understand speech, follow directions, and learn effectively. APD often goes undiagnosed or misunderstood, leaving many individuals struggling with daily communication and academic challenges.
What is APD?
APD is a complex condition that affects how the brain processes auditory information. It is not a hearing problem, but rather a difficulty in understanding and interpreting sounds, especially speech. Kids with APD can’t understand what they hear in the same way other kids do because their ears and brain don’t fully coordinate. Something interferes with the way the brain recognizes and interprets sounds, especially speech.
The auditory system isn’t fully developed until kids are about 14 years old. Many kids diagnosed with APD can develop better listening skills over time as their auditory system matures. Early diagnosis is important. If the condition is not identified and managed early, a child is at risk for listening and learning problems at home and school.

Common symptoms
Symptoms of APD can range from mild to severe and can take many different forms. Some common signs and symptoms include:
- Trouble understanding speech, especially in noisy environments
- Difficulty following verbal directions, whether simple or complicated
- Trouble with spelling, reading, or phonics
- Difficulty with verbal math problems
- Trouble following conversations
- Often mishearing sounds and words
Kids with APD can have trouble understanding what is being said to them when they’re in noisier places like a classroom, playground, sports event, school cafeteria, or party.
Differences from other conditions
APD is often misunderstood because many of its symptoms are similar to those found in other disorders. APD symptoms can be hidden by other problems, like speech-language delays, learning disabilities, attention deficit hyperactivity disorder (ADHD), and depression.
It’s important to note that auditory memory deficits, auditory attention problems, and sound sensitivity are not symptoms of APD, but also may involve trouble with using sound information correctly. Seeing an audiologist and other related specialists can help parents understand these conditions and how they differ from APD.
The Diagnosis Process
Diagnosing auditory processing disorder (APD) involves a comprehensive evaluation by a team of specialists, including audiologists, speech-language pathologists, psychologists, and teachers. The process aims to identify the specific auditory deficits and determine the appropriate treatment plan.
When to seek professional help
If an individual experiences difficulty understanding speech, following verbal directions, or struggles with reading and spelling, it may be time to seek professional help. Children with APD often have trouble paying attention, understanding words spoken quickly or in noisy environments, and may frequently ask for repetition or clarification.
Types of diagnostic tests
Audiologists play a crucial role in diagnosing APD by administering a series of tests in a sound-treated room. These tests may include:
- Tympanometry: Assesses the movement of the eardrum in response to air pressure changes.
- Acoustic reflex test: Evaluates the ear’s response to loud sounds.
- Auditory brainstem response: Measures how well the inner ear and brain pathways process sound.
- Evoked potential test: Determines how efficiently sound travels along the nerves connecting the ears to the brain.
Additionally, computer-based programs may be used to train the brain to recognize and understand sounds, similar to auditory training conducted by therapists.

Specialists involved
A multidisciplinary team approach is essential for accurately diagnosing and understanding the cluster of problems associated with APD. The team may include:
- Audiologists: Responsible for conducting hearing tests and diagnosing APD.
- Speech-language pathologists: Assess written and oral language, speech, and related capabilities.
- Psychologists: Evaluate cognitive functioning and mental health.
- Teachers: Provide insights on academic difficulties and learning challenges.
It is important to note that while the multidisciplinary team contributes valuable information to understand an individual’s strengths and weaknesses, only an audiologist can make the actual diagnosis of APD. Accurate diagnosis is crucial for determining the specific type of auditory deficit and developing an individualized treatment plan.
Treatment Options for APD
Treatment for auditory processing disorder (APD) typically involves a combination of approaches tailored to the individual’s specific needs. The primary goal of treatment is to improve auditory processing skills, enhance communication abilities, and help the person better cope with their auditory challenges. The following are the main treatment options for APD:
Auditory training
Auditory training is a key component of APD treatment, aiming to improve the brain’s ability to process and interpret auditory information. It involves engaging in structured listening exercises designed to target specific auditory deficits, such as temporal processing, dichotic listening, or auditory discrimination. These exercises may include:
- Listening to and identifying different sounds, tones, or speech patterns
- Practicing listening in the presence of background noise
- Engaging in dichotic listening tasks, where different stimuli are presented to each ear simultaneously
Auditory training can be conducted in a clinical setting with the guidance of an audiologist or speech-language pathologist, or through computer-based programs that can be used at home.
Assistive listening devices
Assistive listening devices (ALDs) can help individuals with APD better access and understand auditory information in various settings. Some common ALDs include:
- FM systems: These devices consist of a microphone worn by the speaker and a receiver worn by the listener, which helps to amplify the speaker’s voice and reduce background noise.
- Sound-field systems: These systems use strategically placed speakers to evenly distribute sound throughout a room, making it easier for individuals with APD to hear and understand speech.
- Personal amplifiers: These small, portable devices amplify sound directly into the listener’s ears, helping to improve speech clarity and reduce background noise.

Environmental modifications
Modifying the listening environment can significantly improve auditory processing for individuals with APD. Some effective environmental modifications include:
- Reducing background noise: Minimizing sources of competing noise, such as fans, air conditioners, or outside traffic, can help improve speech clarity and understanding.
- Improving room acoustics: Using sound-absorbing materials, such as carpets, curtains, or acoustic panels, can help reduce echo and reverberation, making speech easier to process.
- Preferential seating: Placing individuals with APD closer to the speaker or in a location with the best acoustics can enhance their ability to hear and understand speech.
In addition to these primary treatment options, individuals with APD may also benefit from language therapy, cognitive skill-building exercises, and the development of compensatory strategies to help them better navigate auditory challenges in their daily lives. A multidisciplinary approach involving audiologists, speech-language pathologists, educators, and family members is essential for creating a comprehensive and effective treatment plan for individuals with APD.
