Sounds around you are not only breaking the silence but some may enliven the day. The voices that can not be separated from everyday life, from the sound of the vehicle, the music, the sound of people talking and even up to the sound of the murmuring not escape from hearing. But in fact, these voices have an effect on physical and psychological health.
Pioneers sound researcher and environmental psychologist, Arline Bronzaft, from the City University of New York, said, “When the ear captures sound waves and then send it to the temporal lobe for interpretation process, the brain will determine whether the sound is unwanted, unpleasant or disturbing.”
Here are seven ways how sound can affect a person’s physical and mental health.
1. Impact on a child’s learning ability.
In a classic study of the sound level and the process of learning, the researchers observed the children in two classes of primary school level in Inwood, New York. This elementary school adjacent to the railway line. These children were divided into two groups. One group was placed in the classroom dealing with railroads, while the other group was placed in a more quiet room in the school building.
According to lead researcher, Bronzaft, sound around the neighborhood quite disturbing school teachers. The teachers can only use 11 percent of their time teaching in the classroom is noisy. To add to the evidence of the linkage learning process with voice, Bronzafit back to the classroom after the rush hour worked. Researchers also adds to the sound of the roof panel repair school. He found, balanced literacy students in the two classrooms.
However, recent studies indicate a link between the academic and developmental delay with noise around the runways, railway lines also motorway. The results of the WHO research shows children who live close to transport links noisy voice, language and cognitive ability is lower. Their reading scores were also lower.
2. Work less productive.
In a recent article in The New Yorker about the open- plan office, Maria Konnikova revealed 70 per cent of the office has an open floor plan. This architectural trend turns out to bring harm to the health, began to spread of the disease, the lack of control over the environment, and decreased productivity due to the surrounding sounds.
The researchers also found that the sound mix of the concept of open-plan offices hampers the employee’s ability to recall information and perform basic tasks, such as arithmetic. Why, the employee not only disturbed the voices in open office but also began to stress arising from this condition.
In a laboratory study simulated open office, the researchers found higher levels of epinephrine workers. The respondents were then asked to complete a series of puzzles. As a result, they were only able to complete the puzzle a little, showed a decrease in motivation.
3. High- risk disease.
According to the WHO and the European Research Commission in 2011, exposure to excessive noise from transport such as runways or railway lines, increase the risk of high blood pressure and heart attacks.
4. Multitasking resistor.
In the work, multitasking is inevitable. According to Stanford University cognitive neural expert, Anthony Wagner, when we ‘re doing a lot of tasks at once in one time, we are less able to block distractions. Well, when the office was filled with disturbing noises even noisy, multitasking people will find it hard to concentrate at work especially to remember their duties before the fault occurred.
5. Music is not always good.
Many people listen to music to cope with the disturbing noise around it. Unfortunately, it is not always good. Music may improve mood and make you more awake. However, listening to music can actually reduce the ability to capture information or remember. Instead, listen to music that does not suit the tastes can improve memory.
6. Not love yourself.
In a study of the link between open office concept with stress, the researchers found women who work in a noisy office less often fix a more ergonomic seating position than those who work in silence. Noisy work environments contribute to health problems such as carpal tunnel syndrome and lower back pain, because the body needs little concern for workers or physical complaints that appear often neglected.
7. Trigger fear and anxiety
You may just not believe in ghosts, but sometimes you goosebumps when you are on certain conditions or in certain rooms. British researchers say there is some evidence to suggest that infrasound or low frequency sound audible to the human ear, can cause effects such as chills and anxiety.
A study to show how this affects a person’s reaction infrasound. The researchers play four contemporary songs to the respondents. Some songs get additional infra sound. Nearly a quarter of respondents reported experiencing an unusual reaction after hearing the sound infra. Like the nape shudder, feeling sad, scared.
“Some researchers have shown that the infra sound can appear at the site is haunted, thus causing a person to experience a strange sensation, and they associate with ghosts. Our findings support this idea,” said psychologist at the University of Hertfordshire, Richard Wiseman, in his presentation at the British Association science conference.
