How noise affects children

Modern life is loud – but what is the impact of excessive sound on your child?

In today’s fast-paced world, noise has become an unavoidable part of daily life. From busy roads and construction sites to televisions, video games and smartphones, children are constantly exposed to different levels of sound. While some background babble is completely normal, research is beginning to reveal how excessive or consistent sound can impact children’s development, health and wellbeing.

As parents, it’s important to understand how this affects children and what can be done to create a more balanced and peaceful environment. Let’s take a closer look.

Children’s health

Noise is more than just an irritation – it can have measurable effects on physical and mental health, even for children. Studies show that exposure to excessive sound levels can increase stress hormones like cortisol and adrenaline in kids, just as it does in adults. Over time, elevated stress hormones may contribute to issues like poor sleep, reduced concentration and anxiety.

Sleep is especially important for children, as it plays a key role in their growth and brain development. The din from traffic, construction or even loud household appliances can disturb sleep cycles, preventing children from getting the rest they need. Poor sleep can lead to fatigue, irritability and difficulty focusing in school, which may ultimately affect academic performance.

In addition to sleep disturbances, high sound levels may contribute to:

• Elevated blood pressure
• Poor digestion
• Increased aggression
• Anxiety and irritability
• Lowered grades

Long-term exposure to loud noise has even been linked to hearing damage, which may go unnoticed until it begins affecting language development and communication. Children who are frequently exposed to high volumes through headphones or music systems may be at higher risk, highlighting the need for volume limits and breaks during listening activities.

Learning and study

One area where noise has a particularly noticeable impact is learning. Children are highly sensitive to auditory distractions, especially in environments like classrooms where concentration is so central to success. Excessive background commotion can make it difficult for children to process information, follow instructions and retain what they’ve learned, and this is the same for environments where they do their homework.

Studies have shown that younger children who attend schools near busy roads or airports may experience delays in language and reading development due to noise interference. This is because loud or sudden sounds disrupt the brain’s ability to focus and filter out unnecessary information, making it harder for kids to absorb new material.

Even at home, auditory clamour can influence learning. Loud music, TV shows and video games may compete with homework time, leaving children feeling overwhelmed and distracted. Creating quiet, dedicated spaces for study and relaxation can go a long way in supporting children’s academic success.

Emotions and noise

The emotional effects of sound on children are equally important to consider. High noise levels can lead to feelings of irritability, frustration and restlessness. Younger children, in particular, may not have the vocabulary to express their discomfort, leading to tantrums or mood swings.

For children with sensory processing difficulties, such as those with autism or ADHD, noise can feel especially overwhelming. Sudden loud sounds might trigger stress or fear responses, making it challenging for these children to feel calm and secure.

On the flip side, excessive quiet can sometimes create its own set of challenges. Children need a mix of activity and calm, and complete silence may leave them feeling isolated. The key lies in finding the right balance between stimulating sounds and restful quiet.

Prolonged exposure to chaotic environments can also increase feelings of helplessness and overstimulation, which can sometimes look like low motivation to do anything. Over time, if this is a regular experience, it can really affect children’s ability to regulate their emotions effectively, impacting their social skills and interactions with others.

Modern life is noisy and overstimulation or a lack of auditory ‘rest’ is a real thing that can easily go unnoticed. A great approach is to trial some soothing moments throughout the day and see if they have a positive impact on your child’s emotional state. This could look like ‘reading time’ together in the evening, perhaps listening to classical music, or colouring together while listening to nature sounds – whatever works for your family! By providing moments of calm within the day, you’ll be giving little ones the tools they need to reset and feel more grounded.

Noise sensitivity may also impact friendships and social experiences and no parent wants to see their little one struggle socially at school or with friends! Children who feel overwhelmed by loud parties, busy classrooms, or noisy playdates may begin to withdraw socially. Helping them manage this by preparing them for noisy situations or offering breaks when needed can build their confidence and resilience in group settings.

A calm environment

So, what can parents do to reduce the impact of auditory disturbances and create a more peaceful environment at home? Here are a few strategies to consider:

Background babble

Turn off TVs and radios when they’re not in use, and encourage children to use headphones at a low volume if they’re watching videos or playing games.

Quiet zones

Designate certain areas of your home as quiet spaces where children can read, study or relax without distractions. This is an essential escape for overstimulated kids.

Noise reduction

Thick curtains, rugs and wall hangings can help absorb sound and reduce echoes in busy rooms. White noise machines or fans can also provide soothing background sounds that mask disruptive sounds.

Outdoor fun

If you live in a noisy urban area, consider spending time in parks or quieter, green spaces where children can unwind and recharge.

Sound boundaries

Teach children about noise levels and encourage them to be mindful of how loud they speak or play, especially when others are resting or working.

Sleep-friendly spaces

Ensure your child’s bedroom is as quiet as possible at night. Blackout curtains, sound machines and avoiding screen time before bed can all help promote better sleep.

The right balance

It’s important to remember that not all sounds are bad. Music, laughter and play are essential parts of childhood and can help nurture your little one’s creativity and sense of connection. What matters most is balance. By being intentional about when and where noise occurs, parents can create spaces that support both activity and calm.

Encouraging children to spend time outdoors will also help. Nature sounds, like birds chirping or waves crashing, have been shown to have a calming effect on both children and adults. Even short walks in the park can help counterbalance the overstimulation of noisy city life.

The role of schools

While much of the focus is on home environments, schools also play a significant role in managing auditory levels for children. Teachers and school administrators can help by creating quieter classrooms, using soft furnishings to dampen sound and ensuring playgrounds are designed with noise control in mind.

Parents can advocate for noise-friendly policies in schools where it is appropriate, such as limiting announcements during class time or scheduling noisy maintenance work outside of learning hours.

Clamour and commotion is an inescapable part of modern life, but its impact on children shouldn’t be underestimated. From affecting sleep and concentration to influencing emotional health, the effects of sound can be far-reaching. The good news is that with a few simple changes, you can create calmer, healthier environments for your family to flourish in. After all, every child deserves a space where they can feel calm, focused and happy.
