For example: avoid very noisy leisure activities, opt for alternatives means of transport such as bicycles or electric vehicles over taking the car, do your housework at recommended times, insulate homes with noise-absorbing materials, etc. International bodies like the WHO agree that awareness of noise pollution is essential to beat this invisible enemy. Interestingly, our ears need more than 16 hours' rest to make up for two hours of exposure to 100 dB. It is also bad for the memory, making it hard to study. Noise may affect people's ability to focus, which can lead to low performance over time. Loud noise can have latent effects on our behaviour, causing aggressive behaviour and irritability. Remember that according to the World Health Organization it should be no more than 30 dB. Noise above 45 dB stops you from falling asleep or sleeping properly. Noise can cause attacks of stress, fatigue, depression, anxiety and hysteria in both humans and animals. Respiratory agitation, racing pulse, high blood pressure, headaches and, in case of extremely loud, constant noise, gastritis, colitis and even heart attacks. As a consequence, it is recommended noise levels be kept below 65 dB during the day and indicates that restful sleep is impossible with nighttime ambient noise levels in excess of 30 dB.Īs well as damaging our hearing by causing - tinnitus or deafness -, constant loud noise can damage human health in many ways, particularly in the very young and the very old. To be precise, noise becomes harmful when it exceeds 75 decibels (dB) and is painful above 120 dB. The World Health Organization (WHO) defines noise above 65 decibels (dB) as noise pollution. Not all sound is considered noise pollution. Experts say noise pollution can interfere with breeding cycles and rearing and is even hastening the extinction of some species. According to the National Park Service (NPS) in the United States, noise pollution has an enormous environmental impact and does serious damage to wildlife. Not only does it hurt humans, it is bad for animals, too. So much so that the European Environment Agency estimates that noise is responsible for 72,000 hospital admissions and 16,600 premature deaths every year in Europe alone. Cities have become the epicentre of a type of pollution, acoustics, which, although its invisibility and the fact that coronavirus crisis reduced it until almost yearn it, is severely damaging to human beings.
