Auditory Processing Disorder (APD) and ADHD

Do you struggle to follow conversations, mishear instructions, or zone out, despite normal hearing? ADHD and auditory processing disorder (APD) share many symptoms and often co-occur.  
A structured assessment can tell you which condition is driving your difficulties, or whether it’s both, get clarity now:

Is There a Link Between Auditory Processing Disorder and ADHD?

While ADHD and APD are separate conditions, they frequently co-occur and share several outward behaviours. Both can cause a person to appear as if they are ‘zoning out’ or ‘not listening’, which is why they are often mistaken for one another. However, while ADHD affects attention and impulse control more broadly, APD specifically impacts how the brain interprets sounds and speech, particularly in noisy environments.

50% of children with APD show significant ADHD symptoms² Up to 70% of children with ADHD show auditory processing difficulties¹

Understanding whether a struggle is rooted in a lack of focus or a processing delay is essential for getting the right support.

Auditory Processing Disorder and ADHD Symptoms

Symptoms vary by age and environment. While auditory processing disorder symptoms involve how the brain interprets sound rather than hearing loss, ADHD affects attention, organisation, and impulsivity more broadly.

Note: Every person’s experience of APD and ADHD is different. The patterns below are intended to help you recognise and name what you might be going through, not to replace a professional assessment.

Common Auditory Processing Disorder Symptoms

The primary signs of auditory processing disorder in children and adults involve difficulty making sense of what is heard, even if a standard hearing test shows normal results. This struggle is most intense in noisy environments or when instructions are complex and multi-layered.
In children:
- Often says ‘What?’ or ‘Huh?’ despite having healthy hearing.
- Frequently mishears or confuses similar-sounding words.
- Struggles to follow multi-step instructions without repetition.
- Performs much better one-on-one than in noisy classrooms.
- Appears to ‘ignore’ people when their name is called.
In adults:
- Great difficulty following group conversations or meetings.
- Finding phone calls stressful or hard to decipher.
- Trouble understanding speech that is rapid or has a strong accent.
- Frequently needing people to repeat themselves.
- Feeling physically or mentally exhausted by the effort of listening.

Common ADHD Symptoms

Living with ADHD often feels like your brain is jumping between several channels at once, making it difficult to regulate focus or physical energy. ADHD symptoms in children often manifest as visible restlessness, while ADHD symptoms in adults tend to appear as internalised struggles with time and planning.

In children:

Easily distracted by background sights or sounds.
Often fidgety or unable to stay seated for long periods.
Frequently forgets or misses instructions.
Rushes through work, leading to careless mistakes.
Often blurts out answers or interrupts others.

In adults:

Significant trouble focusing during long meetings or conversations.
Persistent challenges with time management and deadlines.
Frequently losing essential items like keys or phones.
Making impulsive decisions without considering consequences.
Feeling a constant internal sense of restlessness.

How to know if it’s
Auditory Processing Disorder (APD) or ADHD

Difficulties with listening can arise from ADHD, APD, or a combination of both.

What is Auditory Processing Disorder (APD)?

Auditory Processing Disorder is a difficulty with how the brain interprets sound. Even with “normal” hearing, it makes following speech in noisy environments or complex instructions a major challenge.

What is ADHD?

It is a neuro developmental condition affecting attention, activity, and impulse control. It can manifest as physical restlessness in children or chronic organisational struggles in adults.

Recognise yourself in both columns? If you’re seeing symptoms of both APD and ADHD, the only way to know for certain is a structured assessment. Our clinicians look at the full picture — not just one condition in isolation.

Is it a lack of focus, or a processing delay?

Both conditions can look like 'not listening' or missing details during conversations, especially in noisy group settings. Because of these shared symptoms, ADHD and auditory processing disorder are often confused and mislabelled as a lack of effort or laziness.

The core difference lies in why the information is missed. ADHD affects broad attention and focus regulation across all senses. In contrast, APD is specifically about how the brain handles sound; it is a difficulty with accessing the auditory signal correctly rather than a lack of motivation.

It is possible to have ADHD and auditory processing disorder at the same time. Because symptoms are so intertwined, a specialist assessment, including cognitive screening and listening tests, is the only way to tease them apart and target the root cause.

How Auditory Processing Difficulties Can Look Day to Day

Understanding how APD presents in real-life situations helps clarify why simple listening can feel so exhausting. These examples illustrate common struggles with or without a co-occurring ADHD diagnosis.

In the Classroom or Lecture Hall

A student with auditory processing disorder at school may struggle to isolate a teacher’s voice from background noise like humming projectors. They might mishear similar-sounding words or lose the thread if information is delivered too quickly. When combined with listening difficulties with ADHD, a wandering mind often means they miss the start of instructions entirely.

At Work and in Meetings

In open-plan offices, APD can make speech feel like a wall of indistinguishable noise. Following conference calls or group discussions becomes a high-effort task, often leading to a ‘delayed’ response as the brain decodes sound. Navigating ADHD and auditory processing in the workplace is doubly taxing; as the brain struggles to process the signal, ADHD-related frustration can cause the person to disengage.

In Conversations and Social Situations

Social gatherings in busy cafes are often the most difficult. Someone with APD may rely on lip-reading or frequently ask for repetition to make sense of a conversation. They might appear to ‘zone out’ during long stories, not due to a lack of interest, but because their brain is physically drained by the constant effort of filtering out background chatter.

How ADHD & Auditory Processing Disorder Are Diagnosed

Obtaining a formal ADHD and auditory processing disorder diagnosis requires looking at how you process information from two different angles. As the symptoms overlap, a thorough evaluation is the only way to ensure you receive the correct support and avoid misdiagnosis.

An ADHD assessment is usually carried out by a psychiatrist or specialist clinician. They use a combination of clinical interviews, standardised rating scales, and a detailed look at your developmental history to see if attention and impulsivity patterns have been present since childhood.

Specialist tests for auditory processing disorder are typically performed by an audiologist or a speech and language professional. After first ruling out physical hearing loss, they use specific listening tests to see how the brain interprets sounds in various environments, such as identifying speech against background noise.

Support for ADHD and Auditory Processing Difficulties

Treatment plans for these conditions are highly individual. Clinicians usually focus on the symptoms causing the most daily disruption, often using a mix of environmental adjustments, skill-building, and professional guidance.

Support for ADHD

ADHD treatment options focus on managing attention through behavioural strategies, coaching, and routines.

Practical tools like visual reminders and structured planners are essential for organisation.

Additionally, medication can be discussed with a qualified prescriber to help regulate focus and reduce internal restlessness.

Support for Auditory Processing Disorder

Auditory processing disorder support often involves environmental changes, like reducing background noise or using preferential seating.

Specialists may suggest auditory training or speech therapy to improve sound discrimination.

In some cases, assistive technology like FM systems may be recommended to help clear speech reach the brain.

When ADHD and APD Occur Together

Managing support for ADHD and auditory processing disorder together requires a blended plan.

This combines ADHD-friendly tools, like chunking tasks, with APD-friendly aids like captions and quiet workspaces.

Using digital planners alongside noise-cancelling headphones can significantly reduce the mental fatigue of processing and attending to information simultaneously.

If you recognise the patterns on this page, in yourself or your child, you don’t have to keep guessing.

The overlap between ADHD and APD means that without a proper assessment, it’s very easy to receive support for one condition while the other goes unaddressed.

Our clinical team assesses the full picture. We don’t look at attention and processing in isolation, we consider how these patterns interact, and what that means for your daily life. Whether you’re an adult who has spent years struggling in meetings and conversations, or a parent trying to understand why your child is falling behind despite working hard, a structured assessment is the clearest path forward.

How do I know if it’s ADHD, APD, or both?

The difference between ADHD and auditory processing disorder usually comes down to “focus” versus “signal.” ADHD is a broad struggle with attention across all senses, while APD is specifically about the brain’s struggle to decode sound. A specialist assessment is the only way to be sure.

Can you have both ADHD and auditory processing disorder?

Yes, it is common to have ADHD and auditory processing disorder at the same time. When they co-occur, the effort of trying to focus while simultaneously decoding garbled speech can be incredibly exhausting. We recommend discussing these overlapping patterns with a qualified professional.

Is APD a type of ADHD or a hearing problem?

APD is neither; it is a neurological processing issue. While a person usually passes a standard hearing test, their brain struggles to “translate” what the ears hear. Understanding this distinction in ADHD vs auditory processing disorder in children is vital for getting the right support.

Why does my child say ‘What?’ all the time but pass hearing tests?

This is one of the most common signs parents notice before an APD diagnosis. The ears are doing their job, the problem happens a step later, when the brain tries to decode what it heard. In a quiet room, one-to-one, your child may follow you perfectly. In a noisy classroom, at the dinner table, or when you call from another room, the brain can’t keep up with the signal fast enough.

You may wonder, ‘can ADHD cause auditory processing problems?’ ADHD doesn’t cause APD, but it makes a processing delay significantly harder to manage — because the brain is fighting on two fronts at once. The first step is usually a referral to an audiologist for specific listening tests that go beyond a standard hearing check. Your GP can help you with that referral.

Can ADHD medication help auditory processing difficulties?

ADHD medication may improve general attention, which can help a person “stay tuned in” to a conversation. However, it does not directly treat the underlying sound-processing delay of APD. Always defer to your clinician for a tailored treatment plan.

Who diagnoses auditory processing disorder?

APD is typically diagnosed by an audiologist or a speech and language professional. Because they look at the “auditory signal” while a psychiatrist looks at “attention,” it is often helpful to have both perspectives. Your GP can help you find the correct referral pathway.

What should I do if I suspect ADHD and APD?

Start by noting down specific examples, such as if you or your child struggle more in noisy rooms than quiet ones. Share these observations with a healthcare professional to determine which assessments are needed. A suitably qualified clinician can help provide a clear path forward.
