Attention Advantages with Background Noise

Research Spotlight

Could background sound be the key to improving focus for those with attention-deficit/hyperactivity disorder (ADHD)? Emerging research suggests it can certainly help! A recent study reveals that as we attempt to focus, specific types of background sounds can enhance task performance in individuals with ADHD, opening up new possibilities for treatment. The types of sounds that work best may be white and pink noise, which can block out distractions and help the brain stay attentive. Up to 12% of all employed adults say they have difficulty concentrating on work tasks, so it’s possible that incorporating supportive soundscapes can help teams achieve greater productivity.

ADHD is one of the most common neurodevelopmental disorders, affecting up to 10% of children and youth between the ages of 3 and 17. In adults, the prevalence of ADHD may be around 3% according to recent studies. While traditional treatments like medication and behavioral therapy are effective for many, they come with their own set of challenges. Some experience side-effects, while others may have limited access to care. These challenges drive researchers to find non-pharmacological approaches that are safe and easy to access. Noise exposure has finally been put to the test in populations with ADHD.

Background Noise Variations

White, pink, and brown noise are all types of sound that vary in how they distribute energy across different sound frequencies.

  • White noise, often described as a consistent hissing sound, contains equal intensity across all frequencies and is frequently used to mask other noises.
  • Pink noise, with its deeper, softer tones resembling rainfall or rustling leaves, decreases in intensity as frequency increases.
  • Brown noise has an even steeper drop in intensity, producing a deep rumbling sound akin to distant thunder or a powerful waterfall.

The recent study found that both white and pink noise can modestly improve task performance in people diagnosed with ADHD.

How powerful is this attentional advantage?

To quantify this, researchers find the effect size. The effect size of background white and pink noise is smaller than that of traditional ADHD medications, but it is significant. The potential of brown noise remains unexplored, though its conceptual similarities to white noise suggest it could offer similar benefits. While anecdotal reports suggest that these background sounds help those without ADHD, this study did not find a significant benefit for those without an ADHD diagnosis. 

How background noise helps: 

In ADHD, the brain struggles to pay attention during times when arousal is either too low or too high. Getting the right amount of brain activation is key for mental performance, and ADHD seems to make this sweet spot even more important to target. That’s where background noise comes in: By increasing brain activity just enough, a person can concentrate a little easier. While background sound is not cure, it is a simple and cost-effective approach to helping the brain stay focused!

Put Background Noise to the test

For those with ADHD, these findings offer an intriguing new tool for consideration. Incorporating noise exposure, particularly white and pink noise, could provide an accessible and non-invasive way to help improve focus and attention in those who need it most.

Treo provides a wide array of background sounds that most members use for sleep support, including background noise. While water-based background noises are most popular for falling asleep, our pink and brown noise tracks promise a new use for promoting concentration and attention. While further research will shed more light on sound-based approaches, the current evidence suggests that background noise is a promising option for tuning out distractions and focusing on the task at hand.

Nature is also a great way to connect to your feelings and emotions. Certain sounds convey that the outside world is threatening, even at low decibels. Sounds of nature can help us achieve more positive moods. Nature soundscapes can provide a wonderful outlet for those leading busy or stressful lives. Anything you need, Treo has you covered!
