Why is noise pollution dangerous?

Noise pollution is one of those issues that you may not have considered thoroughly, even if the drill in your neighbor’s apartment or the lawn mower across the street have troubled you several times. Learn how even music may be a danger factor.

Among the issues confronting contemporary society today is noise pollution, which affects everyone equally, much more so if we live in a congested metropolis. Often, though, exposure to noise pollution is a conscious choice, unaware of the consequences. Here is some fascinating information about this subject.

What is referred to as noise pollution?

The term “noise pollution” refers to the propagation of noise that has a detrimental effect on humans and animals. Cars, public transit, and sound propagation systems are the most frequent sources of noise.

Frequently, urban planning is carried out in such a way that it exacerbates this problem. Residential areas next to roads and industrial parks are particularly vulnerable to these issues. However, the issues connected with noise pollution date all the way back to ancient Rome, demonstrating that we humans are directly responsible for a large portion of this unpleasant noise.

What are the typical noise levels in our area, and where are we located?

Decibels are used to quantify the strength of sound – or noise. The World Health Organization recommends a maximum value of 50 dB in residential areas, however field testing has shown an average of 97.6 dB, nearly double the recommended amount.

What exactly is the issue with noise?

If you believe that ambient noise is merely a matter of comfort, you are mistaken; increased levels of noise pollution have been blamed for an increase in the incidence of coronary heart disease, permanent hearing loss, and a negative impact on natural ecosystems, altering the prey – predator relationship.

Noise pollution’s effect on humans

Noise pollution has a detrimental effect on our health and behavior. Noise can create a continual state of stress, which is associated with hypertension, hearing issues (tinnitus, hearing loss), and poor sleep quality. Noise pollution, according to a research published in 2021, is related with accelerated cognitive deterioration.

When noises are unwelcome, when they interfere with a person’s everyday tasks, when they disrupt or make communication difficult, or when they just degrade one’s quality of life, noise pollution is noted. However, one of the most significant consequences of excessive noise is hearing loss.

Noise pollution has a detrimental influence on persons with autism spectrum disorders in particular. Hyperacusis – a heightened sensitivity to sound – is a typical symptom in this group of people, who suffer from dreadful states of anxiety, panic, and unpleasant bodily sensations when exposed to loud surroundings.

Numbers for noise pollution and hearing acuity

The figures that we are about to give are official World Health Organization data on the progression of the population’s hearing acuity.

43 million people between the ages of 12 and 35 appear to have hearing loss, and this number is continually increasing. Over 40% of the industrialized world’s population is exposed to hazardous levels of noise in pubs and clubs.

Adolescents with decreased hearing acuity have grown considerably in recent years, rising to 7.8 percent now from 5.3 percent in 2006 and 3.5 percent in 1994. The pinnacle, and frequently the primary responsibility for this scenario, lies with the playback devices on which the globe is accustomed to listening to music at an excessive level.

Noise pollution and music

While it may seem weird to characterize voluntary music listening in terms of noise pollution, this is a sad truth in some circumstances. The World Health Organization is raising the alarm, as 1.1 billion of today’s youth suffer from some type of irreversible hearing damage as a result of listening to music at excessive level for an extended period of time. The primary remedies to this problem are to limit the duration of exposure to these gadgets and to listen at a moderate intensity. To ensure extra safety, a player should be utilized to no more than 60% of its playback capability.

What are the acceptable levels of noise exposure?

Specialists propose the following values as acceptable upper limits for the duration of noise exposure: A loudness of 85 dB, which roughly corresponds to the amount of noise inside a car, may be safely maintained for eight hours.

A noise level of 90 decibels, as produced by a standard lawn mower, may easily be tolerated for 2.5 hours. 95 decibels is the decibel level generated by a motorbike, which should not be exposed to for more than 47 minutes. The metro and automobile horns emit 100 decibels, which should not be sustained for more than 15 minutes.

At maximum level, an MP3 player “takes out” around 105 dB, and the exposure limit is 4 minutes. A loud rock event exposes you to around 115 decibels, and you should avoid participating for more than 28 seconds.

Are there safeguards in place?

While exposure to noise is voluntary, the keys to success include lowering the level – when listening to music – or limiting the amount of time spent listening.

When exposure is unintentional, as is the case with workers operating industrial machinery, a set of earplugs (here is a comparison list) can provide effective protection. There are several varieties of noise-isolating plugs and even headphones available to preserve good hearing acuity.

WHO says that it is also important to create safety regulations that must be adhered to by clubs and bars with an exceptionally high level of sound, as well as concert halls, which should make available to guests so-called “peace halls” where they can retreat periodically for protection.
