The call for structured sessions was opened mid October 2021. Proposals within the wide field of acoustics are welcome, with special encouragement to consider efforts that help meet the United Nations Sustainable Development Goals. Many of the efforts in acoustics contribute to the better development of the space we live in, improve health and environment, and in reducing adverse effects of undesired sound. With the promotion of the UN SDGs we aim to strengthen the attention to the solutions offered by professionals in the field of acoustics.
