Understanding Why Autistic People Make Noises: A Close Look

Autism is a developmental disorder that affects communication, social interaction, and sensory processing. It’s a spectrum disorder, which means that it can manifest differently in different individuals. One of the common characteristics of autism is difficulty with communication. This can include challenges with verbal and non-verbal communication. As a result, many individuals with autism may use vocalizations as a means of expression.

However, vocalizations in autism are not always related to communication. Autism can also affect sensory processing, leading to hypersensitivity or hyposensitivity to different stimuli. For some individuals with autism, vocalizations can serve as a way to regulate sensory input or seek out sensory stimulation. In other cases, vocalizations may be a form of self-stimulation, also known as stimming.

With that in mind, let’s take a closer look at vocalizations in autism.

Communication Challenges in Autism

If you know someone with autism, you may have noticed that they sometimes make unusual sounds or vocalizations. These sounds may seem out of place or difficult to understand, but they often serve an important purpose in communication. People with autism experience communication challenges that can make it difficult to express themselves in ways that are easily understood.

Autism can affect both receptive and expressive language skills, making it difficult to understand spoken language, follow social cues, and use language effectively. Non-verbal communication can also be a challenge, making it difficult to read body language or understand tone of voice. These communication challenges can lead to frustration, anxiety, and difficulty expressing oneself effectively.

As a result, vocalizations can become a form of communication for individuals with autism. With limited verbal communication abilities, vocalizations may serve as a way to express emotions or convey needs. For example, a person with autism may make a specific vocalization when they are happy or excited. Alternatively, they may make a different sound when they are feeling upset or uncomfortable.

Alternative Communication Methods:

When verbal communication is difficult, individuals with autism may also use alternative communication methods. These can include sign language, picture communication systems, or electronic devices that produce speech. These alternative methods allow individuals with autism to communicate more effectively and reduce the need for vocalizations as a primary form of communication.

Understanding the communication challenges faced by individuals with autism is an important step in understanding vocalizations. By recognising the role that vocalizations play in communication, we can support individuals with autism in expressing themselves in ways that are comfortable and effective for them.

Sensory Processing and Vocalizations

One of the significant factors contributing to vocalizations in autism is sensory processing difficulties. Individuals with autism often experience sensory overload or may seek sensory stimulation, leading to vocalizations as a way to cope. Sensory processing may involve any of the five senses: touch, taste, smell, sight, and sound.

Some individuals with autism may have sensory sensitivities, where they experience certain sensory stimuli as overwhelming or even painful. For example, a loud noise may be unbearable, or a particular texture may feel uncomfortable. In contrast, others may have sensory seeking behaviours, where they may seek out intense sensory experiences.

The relationship between vocalizations and sensory processing can be complex, and it is essential to understand the individual’s specific sensory needs and challenges. For instance, vocalizing may serve as a distraction from an overwhelming sensory experience or provide a sense of comfort in a chaotic environment.

It is crucial to support individuals with autism by providing them with sensory tools and accommodations to help them manage their sensory experiences. Some of these accommodations may include noise-cancelling headphones, weighted blankets, or fidget toys. It is recommended to consult with a sensory processing disorder specialist to develop an individualized sensory plan that could help manage the sensory needs of the individual with autism.

Stimming and Vocalizations in Autism

If you have witnessed an individual with autism making repetitive movements, such as hand-flapping, you may have wondered why they do it. These behaviours, known as stimming, are a common characteristic of autism and serve as a way for individuals with autism to self-regulate their sensory and emotional experiences.

Stimming can also manifest as vocalizations, such as humming or making clicking noises. These sounds may be comforting to the individual and help them filter out overwhelming sensory information. In some cases, vocalizations can also serve as a form of self-expression or social communication.

It’s important to note that stimming and vocalizations are not behaviours that need to be “fixed.” Rather, they should be accepted and supported as a part of the individual’s unique way of coping with the world around them.

There are different types of stimming behaviours, such as visual stimming, auditory stimming, and tactile stimming. Some individuals may engage in multiple forms of stimming, while others may only exhibit one type.

If you are a caregiver or professional working with an individual who stims, it’s essential to understand and respect their stimming behaviours. You can support their self-regulation by providing them with safe and appropriate ways to engage in stimming, such as fidget toys or sensory tools.

Coping Strategies for Vocalizations in Autism

Understanding and managing vocalizations is an essential part of supporting individuals with autism. Here are some coping strategies that can help:

Visual supports: Many individuals with autism benefit from visual aids such as picture schedules or social stories. These can help them understand what is expected of them in certain situations and reduce anxiety that may lead to vocalizations.

Sensory tools: Providing sensory tools such as fidget toys or weighted blankets can help individuals with autism regulate their emotions and reduce the need for vocalizations.

Relaxation techniques: Encouraging relaxation techniques such as deep breathing or meditation can help individuals with autism manage stress and anxiety that may lead to vocalizations.

Positive reinforcement: Rewarding positive behaviours can help reinforce self-regulation and reduce the frequency or intensity of vocalizations.

Individualized approaches: It is essential to develop coping strategies that are tailored to the individual’s needs and preferences. Working with professionals such as occupational therapists or speech therapists can help identify effective coping strategies.

Remember, vocalizations are a form of communication for individuals with autism, and it is essential to understand and respect them. With the right support and coping strategies, individuals with autism can learn to manage their vocalizations and communicate effectively.

Supporting Vocalizations in Autism

As a support system for individuals with autism, it is important to understand and respond to their vocalizations in a supportive and respectful manner. By recognising vocalizations as a valid form of expression, you can create a safe and inclusive environment that promotes self-regulation and emotional wellbeing.

One effective way to support vocalizations in autism is by providing appropriate interventions. These interventions may include visual supports, social stories, and sensory tools that can help promote self-regulation and reduce the frequency or intensity of vocalizations. It is important to note that interventions should be individualised to meet the unique needs and preferences of each person with autism.

In addition to interventions, creating an inclusive environment that respects and values the expressive forms of individuals with autism is crucial. This may involve educating peers and caregivers about the importance of vocalizations in autism and providing accommodations that support self-expression and participation in social activities.

As a support system, it is also important to recognise your role in providing emotional support and validation for individuals with autism. By listening actively and responding with empathy and understanding, you can help promote emotional wellbeing and reduce stress levels.

Overall, supporting vocalizations in autism requires a combination of interventions, accommodations, and emotional support. By taking a person-centred approach and promoting self-expression and emotional regulation, you can create a positive and inclusive environment for individuals with autism to thrive in.


Now that you have a better understanding of why autistic people make noises, it’s important to recognise and support their self-regulation of sound. Vocalisations can serve as a crucial form of communication and self-expression for individuals with autism, especially when faced with communication challenges or sensory overload.

There are various interventions and coping strategies available to support individuals with autism and their vocalizations. These can include visual supports, social stories, and sensory tools that aid in self-regulation and reducing the frequency or intensity of vocalizations. It’s essential to recognise that each person with autism has unique needs and preferences, and interventions should be tailored to their individual circumstances.

Creating inclusive environments that value and respect diverse forms of expression is also crucial in supporting vocalizations in autism. This involves ensuring that professionals, caregivers, and peers are adequately informed and equipped to provide appropriate support and accommodations for individuals with autism and their vocalizations.
