Noise pollution occurs when surrounding noise levels exceed 80dB, which is the limit of permissible human hearing. It has both natural causes like volcanoes and earthquakes, but is mainly caused by human activities like vehicles, construction equipment, factories, and loud daily activities. The consequences of noise pollution include effects on mental health like anxiety and stress, physical health issues like hearing loss and increased blood pressure, and interference with animals' abilities. Some measures to prevent noise pollution are using earplugs, soundproofing walls and doors, installing soundproof panels, and planting trees.

NOISE POLLUTION
1. What is noise pollution?
- Noise pollution is a condition in which the noise in your surrounding environment exceeds the permissible threshold of human hearing. So what is the permissible hearing threshold for humans? Normally, normal people's ears can hear up to 194dB, but the allowable noise level is only from 0dB to 80 dB. Therefore, sounds with an intensity greater than 80dB can cause noise pollution. 2. Causes of noise pollution – - Can be divided into 2 causes of noise pollution: Natural causes and human causes. • Natural causes - Volcanoes and earthquakes are natural activities that cause noise pollution. • Human causes - This is the main cause of noise pollution today, having a strong and frequent impact on human activities • Noise pollution from vehicles - Engine sounds, sounds Car horns, planes taking off, ships... are the main factors causing a large amount of noise today. • Noise pollution from construction and production activities - Construction activities always have noise caused by mechanical equipment such as excavators, bulldozers, excavators... The high intensity of this sound mainly comes from milling factories and metallurgy factories... • Noise pollution due to daily activities - Currently, people often have the habit of using box speakers and singing karaoke at high volume... which significantly affects their hearing. sense of the listener. 3. Consequences of noise pollution - Effects on people + Effects on mental health: Loud or frequent noise can cause anxiety and stress in people. Noise is one of the causes of sleep disorders. +Effects on physical health: Loud sounds can cause hearing loss. Short- term noise pollution can temporarily increase blood pressure. Long-term exposure can increase the incidence of cardiovascular disease, and increase blood viscosity... - Effects on animals: Too loud noise will hinder the animal's ability to find food. 4. Measures to prevent noise pollution + Use noise-canceling earplugs + Make plaster ceilings + Use soundproof doors + Use soundproof panels + Plant lots of trees
