This special session is focused on nonlinear acoustics applied to 3D audio systems.

Every audio system could be affected by nonlinearities introduced by the sound reproduction and acquisition chain.

In nonlinear systems, the output signal presents additional frequency components that are not contained in the original signal. This aspect becomes important in immersive audio systems, which require a high fidelity reproduction and a realistic identification of the environment.

 We are pleased to invite you to submit scientific contributions on the following topics but are not limited to:

 – nonlinear audio system identification

– nonlinear 3d auralization

– acoustic measurements for nonlinear systems

– nonlinear sound propagation

– nonlinearities in 3d audio systems

Chairs:  Stefania Cecchi & Valeria Bruschi

Stefania Cecchi was born in Amandola, Italy, in 1979. She received a Laurea degree (with honors) in electronic engineering from the University of Ancona (now University Politecnica delle Marche, Italy) in 2004 and a Ph.D. degree in electronic engineering from the University Politecnica delle Marche (Ancona, Italy) in 2007. She was a postdoc researcher at DII (Department of Information Engineering) at the same university from February 2008 to October 2015 and an Assistant Professor from November 2015 to October 2018. She is an Associate Professor at the same department since November 2018. She is the author or coauthor of numerous international papers. Her current research interests are in the area of digital signal processing, including adaptive DSP algorithms and circuits, speech, and audio processing. Prof. Cecchi is a member of the AES, IEEE, and the Italian Acoustical Association (AIA).

Valeria Bruschi received the M.Sc. degree (cum laude) in electronic engineering in 2018 at Università Politecnica delle Marche, Ancona, Italy, with a thesis on immersive sound reproduction in real environments. She is going to obtain the PhD by June 2023 at the Department of Information Engineering of the same university and she has currently a postdoc fellowship at the same department. The main topic of her PhD deals with innovative systems for immersive audio rendering enhancement. Her current research interests are mainly focused on digital audio signal processing (DSP), with particular attention to adaptive DSP algorithms for linear/nonlinear systems identification, audio equalization and immersive audio systems. She is a Student Member of the Audio Engineering Society (AES).
