Importance of Sound
for Society and the World

The International Year of Sound is a global initiative to highlight the importance of sound and related sciences and technologies for all in society. The International Year of Sound will consist of coordinated activities on regional, national and international levels. These activities will aim to stimulate the understanding throughout the world of the important role that sound plays in all aspects of our society. As well, 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.

The IYS 2020-2021 student competition has reached its final stage!

For the final assessment in the competition, entries for both categories (Category I – drawings, Category II – stanzas) were received from 16 countries: Argentina, Chile, Croatia, Egypt, Greece, Hong Kong, Hungary, Italy, Portugal, Russia, Serbia, Slovenia, Spain, Thailand, Turkey and USA.

For category I (primary schools), 39 drawings were selected as finalists from among more than 650 entries sent to the national representatives. For category II (middle and secondary schools), 33 stanzas were selected as finalists from among more than 50 items sent to national representatives. Moreover, 23 additional contributions, in terms of video and audio tracks, were submitted. Many of the finalist entries will be featured in a video which will be an ongoing record of the outstanding innovative and creative ideas from students around the world on "My World of Sounds".

The IYS Competition Office, for the whole duration, of the competition has maintained contact with the 39 national representatives and the IYS steering committee.

The Students competition is sponsored by the Head-Genuit foundation and was coordinated by Sergio Luzzi assisted by a team of experienced colleagues.


Sound plays an important role in all human activities and applications of acoustics are found in almost all aspects of modern society. Subdisciplines include 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. Sound is an essential part of communication between humans - in the form of speech, as a sound of warning, and also in music and creative sounds. However there is a concern about too much sound, which then becomes noise and needs to be controlled to ensure acceptable and safe living and working environments.
