Why noise irritates some people more than others: It's all in the brain
Noise sensitivity, often dismissed by health professionals, can significantly impact both mental and physical wellbeing. Affecting up to 40% of the population, this condition is linked to anxiety, sleep disturbances, and long-term health risks. read more While noise sensitivity is often overlooked by health professionals, it can have long-lasting effects on the mental and physical wellbeing of humans. Studies suggest that between 20% to 40% of people are more sensitive to everyday sounds than the average, leading to a higher levels of stress, annoyance, or anxiety. Research shows that noise sensitivity has biological roots rather than being just a personality trait. In recent years, neuroscientists have discovered that the brains of noise-sensitive people process sound differently, which might make them more reactive to noise. STORY CONTINUES BELOW THIS AD Daniel Shepherd, a neuroscientist at Auckland University of Technology in New Zealand stated, 'It's been one of those what we might call a wastepaper basket sort of issues… that just gets pushed away by health professionals." Only in recent years 'have people actually really started to say, right, this is at an experiential level really impacting patients', he added. 'We really need to actually start getting a handle on this.' Although noise sensitivity is not a formal medical diagnosis, but it can be identified via questionnaires like the 21-question Weinstein's noise sensitivity scale, which assesses reactions to various everyday sounds. It differs from similarly related conditions such as misophonia, which involves a strong negative reaction to specific sounds like chewing or tapping, or hyperacusis, where sounds are perceived as louder or more painful than they really are. In contrast, noise sensitivity includes a heightened reactivity to a wide range of sounds, irrespective of its volume. Physiologically, the noise can trigger a 'fight-or-flight' response in sensitive individuals, and can raise their heart rate and blood pressure. In some cases. sleep can also be affected. A 2021 study of 500 adults in China found that while noise itself did not drastically change sleep quality, noise-sensitive participants reported feeling less rested and more fatigued the day after. STORY CONTINUES BELOW THIS AD There are connections to long-term health as well. Research led by Professor Stephen Stansfeld at Queen Mary University of London found that noise-sensitive men in the Welsh town of Caerphilly were more likely to face anxiety and depression when exposed to road traffic noise. A 2023 French study of residents near airports reported that those who were highly disturbed by aircraft noise were more likely to rate their general health as poor. Brain studies provide more insights. According to Shepherd's research, noise-sensitive individuals have increased brain activity in response to both threatening and non-threatening sounds. This may be linked to differences in the medial geniculate nucleus, which is a part of the brain that filters sound information, which appears less efficient at filtering out irrelevant noise. The reduced filtering is also observed during sleep, where fewer brain 'spindles' happen, making it harder to adapt to background noise. The causes of noise sensitivity are still being explored. While twin studies from Finland suggest there might be a genetic component, environmental factors might also play a role. STORY CONTINUES BELOW THIS AD The condition is more common in individuals with anxiety, schizophrenia, autism, or a history of brain injury, and it often lasts a lifetime. Addressing noise at its source looks like the most effective long-term solution. Urban planning measures like sound-dampening road surfaces, noise barriers, reduced speed limits, and quiet zones have been put in place in some European cities. However, the change is slow, and many people cope with noise sensitivity symptoms by themselves by using ear protection, or noise-cancelling devices. In certain cases, treating underlying issues like anxiety with medication or cognitive behavioural therapy can help lessen the stress. Music therapy that uses soft, calming tunes, such as Renaissance or Baroque chamber music, may also be useful. Art therapy can offer a different way to relax and manage emotions. While noise is an unavoidable part of modern life, understanding its effects on sensitive people could lead to better public health measures and, ultimately, quieter and healthier living environments.

'Security is everyone's responsibility' – Firas Jadalla, Genetec
Firas Jadalla, Regional Director for the Middle East, Turkey & Africa at Genetec spoke to Daniel Shepherd from CPI Media Group at the Genetec empower360 roadshow in Dubai. The event delved into the importance of open architecture and IoT technologies in developing smarter cities. There was also a strong focus on new trends in access control technology, simplifying video management and providing advanced scalable solutions. With almost 20 years at the Genetec, Firas Jadalla has witnessed their humble beginnings in 2005, to its expansion across nine Middle Eastern cities. In addition to their focus in Dubai and Riyadh, Genetec has local teams in Doha, Cairo and Cape Town South Africa. They have also been recognised as a leader in innovation worldwide with headquarters in Montréal and offices in multiple countries. Which security trends do you believe organisations should keep in mind when it comes to secure solutions? When you consider security, we are seeing more awareness around cybersecurity which was triggered by the pandemic. We see more end users and system integrators looking for solutions that can meet the current challenges of cybersecurity. Another element is an increased focus on unification. 20 years ago, people were interested in the idea of having an interface between physical security solutions. They wanted to have alarms, control systems and video feeds interfaced together, which we now know as integration. Today, the trends are more focused around unification. In integration multiple different systems are combined definitively for efficiency and unification represents a unique concept. To elaborate on the last point, how does unified security differ from current security solutions businesses use? When we talk about a built-in unified product there is a big difference between that and an integrated solution. A unified solution is built from the ground-up with the same code and aspects as most physical products. With unified solutions we take one solution that can meet all your requirements such as physical security, video management, access control system, license distribution system, intercom and more. Some projects might not require all these features, but broadly it provides one solution with one interface. Consider it like Microsoft Office which includes Excel, PowerPoint and Word under a familiar interface. With the Genetec Unified Platform, it is one platform and one interface that meets all these requirements in a seamless package. This is advantageous because it becomes easier to deploy, train employees or perform updates without breaking any links. Do you see cloud security solutions becoming more common or is hybrid still popular with your customers? All of us in Genetec agree that the cloud is going to dominate the future of security solutions. For us it is not a question of will, it is a question of when. When will we see this adoption reach over 50%? When will over 50% of physical security installations rely on an on-prem cloud? When you look at enterprise solutions, there is a bigger appetite for hybrid verses cloud. If we look at small deployments like shop cameras, the owners will likely prefer everything to be linked via cloud. However, with bigger examples like airports that use thousands of cameras it becomes more meaningful and cost effective to use a hybrid solution. Hybrid offers the best of both worlds as you can address issues related to bandwidth and the cost of bandwidth whilst being able to use cloud access from anywhere to gather insights. Can your security centre solutions incorporate and develop alongside the changes we are seeing in access control technology? Our flagship product offers a unified platform for management control. What you get with this platform is that every time a software update is available you only need to do it once to keep things running smoothly. There are no unnecessary integration links or interfaces. Our latest products feature an element called GUS (Genetec Upgrade Service) which when enabled, automatically checks for updates during night hours. Before we wrap up, is there anything else you would like to say to our readers? As a company, Genetec has taken a very strong stance on cybersecurity since 2016. We've seen people become aware of the importance of having a secure security solution right after the pandemic. During that time more people were working from home leading to an increase in the number of cyberattacks. We've continued to encourage our system integrator, channel partners and end users to give cybersecurity the importance it is due. At Genetec, with have improved our solutions with built-in cybersecurity and created guidelines for our system integrator during deployment to tighten security measures. Our solution includes many features such as, encryption to avoid man-in-the-middle attacks between cameras and the servers' workstation. I would like to take this opportunity to remind people of the critical nature of their own security systems and at the end of the day it is everyone's responsibility. Whether it's Genetec being the supplier, our system integrator deploying it or the end user running it, everyone is accountable. We must all work together to share the responsibility.
