Why Does Loud Noise Cause Stress?
“Noisy or too hard background sound at work, home or school can disrupt one’s concentration, this condition will make the stress level increases,” said Mark AW Andrews, director and professor of psychology at the Lake Erie College of Osteopathic Medicine at Seton Hill University, Greensburg, according to Scientificamerican.
It is also agreed by the National Institute for Occupational Safety and Health which revealed noise can increase stress levels and affect one’s health such as high blood pressure, coronary disease, peptic ulcer (ulcer) and headaches or migraines. It also can aggravate a person’s health condition that already exists.
Several studies have shown that the stress of a noisy sound can trigger the release of cortisol (stress hormone). The advantages of these hormones can damage the function in the prefrontal cortex which is central of emotional learning. This area also serves to regulate the functions of planning, reasoning and impulse control or stimulation.
The latest evidence even shows that the prefrontal cortex also store short-term memory. Because of disturbances in this area due to noise, it can hamper a person’s ability to think clearly and store information.
If the stress due to the noise occur continuously, it can cause a higher decline in brain function, especially to the process of learning and memory.
Besides causing people to get angry, noise can also trigger problems in the auditory system such as deafness. This is because loud sounds or noise can be deafening and damage hearing. The earlier a person listens to loud music or voices, the faster the possibility they became deaf.
