International Noise Awareness Day is an annual observance held on the last Wednesday of April. This global campaign aims to raise awareness of the impact of noise on the health and welfare of people.

The term “noise” refers to any unwanted sound. While quiet noise can be simply annoying, loud noise can be harmful. Frequent exposure to prolonged loud noise often leads to noise-induced hearing loss. Noise not only annoys us and damages hearing, but it can also cause elevated blood pressure, anxiety, insomnia and other health problems.

International Noise Awareness Day was launched by the Center for Hearing in Communication in 1996 to raise awareness of the harmful effects of noise and encourage people to do something about bothersome noise where they live. The Center coordinates events held around the world.
