Managing Auditory Sensitivities in Children with Autism

What are auditory sensitivities, and how can parents identify them in young or nonverbal children with autism?

Auditory sensitivities are common in children with autism and other sensory challenges. These sensitivities often lead to behaviors like covering their ears, even when sounds are not excessively loud. Children may show heightened or reduced sensitivity, resulting in various behavioral responses (Sinclair et al., 2017).

Experts believe auditory sensitivities are linked to differences in the limbic system, the brain region that processes emotions and reactions to sensory input (Danesh et al., 2015). In neurotypical children, the limbic system becomes less sensitive as they age. However, in autistic children, it may remain overly active. This helps explain why nearly 70% of people with autism experience hyperacusis and extreme sensitivity to everyday sounds like flushing toilets or alarms (Danesh et al., 2021).

Parents can identify auditory sensitivities by observing their child’s response to sounds. Common signs include:

• Covering their ears or avoiding noisy environments.
• Meltdowns or anxiety triggered by specific sounds.
• Self-soothing behaviors like rocking or humming when exposed to loud noises.

How do auditory sensitivities affect children with autism in daily life?

Auditory sensitivities can significantly disrupt a child’s day-to-day life, affecting emotional well-being, learning, and social interactions. For instance, children may avoid noisy places like schools, malls, or family gatherings, limiting their social and educational opportunities.

Background noise can make it difficult for children to focus, often leading to frustration during conversations or classroom activities. Loud or sudden sounds can also trigger meltdowns, feelings of anxiety, or shutdowns, making emotional regulation challenging. Over time, these issues can lead to social isolation and strained peer relationships.

Even at home, auditory sensitivities can disrupt sleep, as children may struggle to fall or stay asleep due to environmental noises. Families often need to adjust their routines or create quiet, sensory-friendly spaces, which can add stress to daily life.

What tools can parents use to help children with autism manage auditory overload?

Managing auditory sensitivities often requires a combination of preparation, tools, and emotional support. Here are some practical strategies:

• Plan and Prepare: Use visual schedules to help children anticipate potentially noisy environments, reducing anxiety. Establish consistent routines with designated quiet times to provide a sense of security.
• Noise Management: Invest in child-friendly noise-canceling headphones or soft earplugs to minimize exposure to loud sounds. Additionally, provide visual or verbal cues to prepare children for sudden noises, such as the sound of a fire alarm or vacuum cleaner.
• Create Calming Spaces: Designate a quiet area at home where children can retreat when overwhelmed. Include comforting items like pillows, blankets, or sensory toys.
• Teach Coping Skills: Introduce calming techniques like deep breathing or sensory tools like weighted blankets or compression clothing to help children self-regulate.
• Build Understanding: Use social stories to explain sounds and situations, helping children process and reduce noise-related anxiety. Encourage open communication so they can safely express their feelings about sounds.
• Reinforce Positivity: Acknowledge and praise children when they use effective coping strategies, building their confidence in managing auditory overload.

How does sensory integration therapy help children with autism and auditory sensitivities?

Sensory Integration Therapy, a play-based approach, is designed to help children process and respond to sensory input more effectively, reducing sensory-related challenges.

These activities gradually expose children to different sounds, helping them form positive associations and reducing anxiety. This therapy is particularly beneficial for improving the brain’s ability to process sensory input, assisting children to feel less overwhelmed by everyday sounds.

When should parents consider sensory integration therapy for their child?

Parents should consider consulting a certified occupational therapist (OT) if their child exhibits any of the following:

• Frequent distress or discomfort from everyday noises like loud appliances or bright lights.
• Extreme reactions, such as anxiety, or minimal responses to sensory input.
• Avoidance of activities or environments due to sensory sensitivities, such as skipping group outings or school events.
• Difficulty concentrating in noisy or busy settings, impacting learning or social interactions.

An OT can assess the child’s needs and develop a tailored sensory integration plan to address auditory sensitivities.
