How does Noise Pollution affect our health?

What is Noise Pollution ?

Noise pollution is generally defined as regular exposure to elevated sound levels that may lead to adverse effects on humans or other living organisms.

The World Health Organization estimates that one out of three people in Europe is harmed by traffic noise. More than the purely medical effects of noise pollution on the individual, there is a significant social and economic impact. Since noise pollution leads to sleep disturbance, it affects the individual’s work performance during the day, leads to hypertension and cardiovascular disease, costs the health system additional time and money, and it negatively affects school performance in children.

Where does Noise Pollution come from ?

This type of pollution is so omnipresent in today’s society that we often fail to even notice it anymore:

- street traffic sounds from cars, buses, pedestrians, ambulances, etc.

- construction sounds like drilling or other heavy machinery in operation

- airports, with constant elevated sounds from air traffic, i.e. planes taking off or landing

- workplace sounds, often common in open-space offices

- constant loud music in or near commercial venues

- industrial sounds like fans, generators, compressors, mills

- train stations traffic

- household sounds, from the television set to music playing on the stereo or computer, vacuum cleaners, fans

and coolers, washing machines, dishwashers, lawnmowers, etc.

- events involving fireworks, firecrackers, loudspeakers, etc.

- conflicts generate noise pollution through explosions, gunfire, etc. The dysfunctions, in this case, are likely

caused by the conflict and insecurity and less by the noise pollution in itself, although that compounds the stress

levels too.

What are the major health issues caused by Noise Pollution ?

Whether we realize we are subjected to it or not, noise pollution can be hazardous to our health in various ways.

Hypertension

This is a direct result of noise pollution for a longer period of time, which elevates blood levels. 

Hearing Loss

can be directly caused by noise pollution, whether listening to loud music in your headphones or being exposed to loud drilling noises at work, heavy air or land traffic, or separate incidents in which noise levels reach dangerous intervals, such as around 140 dB for adults or 120 dB for children.

Sleep Disturbances

Caused by constant air or land traffic at night, they are a serious condition in that they can affect everyday performance and lead to serious diseases.

Child Development

Children appear to be more sensitive to noise pollution, and a number of noise-pollution-related diseases and dysfunctions are known to affect children, from hearing impairment to psychological and physical effects. Also, children who regularly use music players at high volumes are at risk of developing hearing dysfunctions. In 2001, it was estimated that 12.5% of American children between the ages of 6 to 19 years had impaired hearing in one or

both ears.

Cardiovascular Disease

Elevated blood pressure caused by noise pollution, especially during the night, can lead to various cardiovascular diseases.

Dementia

Dementia isn’t necessarily caused by noise pollution, but its onset can be favored or compounded by noise pollution.

Psychological Dysfunctions

Psychological dysfunctions and noise annoyance. Noise annoyance is, in fact, a recognized name for an emotional reaction that can have an immediate impact.

The effects of Noise Pollution on Wildlife and Marine Life

Our oceans are no longer quiet. Thousands of oil drills, sonars, seismic survey devices, coastal recreational watercraft, and shipping vessels are now populating our waters, and that is a serious cause of noise pollution for marine life. Whales are among the most affected, as their hearing helps them orient themselves, feed, and communicate. Noise pollution thus interferes with cetaceans’ (whales and dolphins) feeding habits, reproductive patterns, and migration routes, and can even cause hemorrhage and death.

Other than marine life, land animals are also affected by noise pollution in the form of traffic, firecrackers, etc., and birds are especially affected by the increased air traffic.

Tips for Avoiding Noise Pollution

- Wear earplugs whenever exposed to elevated noise levels

- Maintain a level of around 35 dB in your bedroom at night, and around 40 dB in your house during the day

- If possible, choose your residential area as far removed from heavy traffic as you can

- Avoid prolonged use of earphones, especially at elevated sound levels

- If possible, avoid jobs with regular exposure to elevated sound level

Monitor Noise Pollution seamlessly with the Butterfly

The Butterfly has a noise sensor that is always listening, even when not asked to take a reading. The noise level that triggers the sensor to wake up, start taking readings automatically, and notify you are pre-programmed based on the application selected, i.e. 35dB for baby monitoring or 70dB for Tenant monitoring. These defaults are very easily changed using the Conscious app. Once triggered, noise levels are measured every minute (again, time can be changed) and notifications are generated if noise is not abated. Additionally, for historical noise data, the Butterfly also records noise levels every 5 minutes (again, timing can be changed).
