Road traffic noise has a detrimental effect on cognitive performance, especially in office buildings.
- Traffic noise to which people who work near roadways are exposed affects their performance.
- The traffic noise to which people who work near roadways are exposed affects their performance.
- These situations are increasingly numerous due to urban densification.
- Even moderate background noise has an impact on cognitive abilities and the feeling of difficulty in accomplishing a task.
Road traffic noise is often considered a nuisance, but it can have serious consequences for the health, well-being and productivity of employees. A recent study by researchers at Chalmers University of Technology in Sweden demonstrated that this noise can disrupt the cognitive performance of employees at work.
The study found that even low noise levels of 40 decibels – a common level in an office environment – can have a negative effect on ability to concentrate and process information. The tasks seem more difficult to perform and the results are worse than in the absence of background noise.
Noise harmful to health and well-being at work
Noise in the work environment can cause stress, fatigue, anxiety, distraction and reduced motivation. However, more and more people are exposed to that which is generated by road traffic. Indeed, with urban densification in large cities, more and more professional premises are being built near road traffic axes.
Low frequency noises difficult to eliminate
The researchers pointed out that limiting vehicle speeds will not solve the problem. Low-frequency noise generated by cars is indeed difficult to eliminate, even with well-insulated windows and buildings that meet sound and acoustic insulation standards.
The researchers suggest that new constructions should be further away from main traffic routes. they say their study reinforces the importance of considering environmental factors in urban planning and building design.
