Even before 11 pm, exposure to loud noises is undesirable. Noise pollution is defined to be harmful or annoying levels of audio output. Whilst this is often passed off as simply a nuisance, recent studies conducted by the European Environmental Agency reveal noise pollution is the second most detrimental pollutant to human health.
How does noise pollution impact health?
A pollutant overlooked too often, noise pollution has been observed to be the primary contributor to conditions such as tinnitus, loss of hearing as well as hypersensitivity towards sound. In addition to this, research is proving it to be heavily influential in conditions such as cardiovascular issues, irregular sleep, and diabetes. Furthermore, stress and mental health issues have also been exacerbated by noise. Ongoing research is ascertaining a possible connection between noise and dementia.
Climate change, Urbanisation and Noise Pollution
Global warming may impact the exposure levels of noise humans may face for a variety of reasons. Environmentally degrading practices such as the extraction of fossil fuels, traffic, and construction all generate ample amounts of noise as well as expelling materials that act as natural sound buffers; trees and open space help to mitigate noise pollution. Warmer temperatures necessitate the use of air conditioners and fans during the summer months, increasing noise levels within the home.
Noise and the Stress Response System
It is not just noise itself that is detrimental to human health, but also the vibrations loud sounds emit. Studies conducted by Harvard academics have revealed that noise emitted by vehicles can cause an increase in activity in the amygdala, where emotions are processed and regulated in the brain. This increase in activity occurred in all people, even if they did not seem to be bothered by the noise, producing the effects of stress on the body when exposed to noise. This portion of the brain can increase stress and inflammation of nerves, leading to cardiovascular conditions and an unstable metabolism.
How can I lessen the impact of noise pollution?
Scientists and researchers alike have recommended the use of earplugs when exposed to high levels of noise. If living in a busy area, an investment in soundproofing cladding may be beneficial to your long-term health. Harvard associate professor Peter James recognises that such levels of noise exposure are inevitable when one is residing in an urbanised area, and the government should therefore prioritise noise pollution research and implement practices to mitigate it.
