Sounds affect our environment, communication, culture, health and wellness. The International Year of Sound is a global initiative to highlight the importance of sound and related sciences and technologies for all in society. It aims to further the understanding of the important role that sound plays in all aspects of our society. These activities will also encourage an understanding of the need for the control of noise in nature, in the built environment, and in the workplace. During the Edit-a-thon for the International Year of Sound 2020, participants will get the chance to learn the basics of Wikipedia editing, make substantive changes to Wikipedia articles within the areas of expertise related to sound, acoustics, aeroacoustics, audio, signal processing, architectural acoustics, bioacoustics, electro-acoustics, environmental noise, musical acoustics, noise control, hearing and psychoacoustics, physical acoustics, speech, ultrasound, underwater sound and vibration.
