The GTM organized two special sessions and presented 6 works in the e-Forum Acusticum 2020

The e-Forum Acusticum 2020 took place as an online version from December 7 to December 11, 2020. 700 oral presentations and 56 poster presentations were proposed to the 1100 attendees.

The GTM organized 2 special sessions and presented 6 works in the congress. The special sessions were:

• “Smart cities and sensors”. Organizer: Prof. Francesc Alías
•  “Mid and high frequency modeling in vibroacoustics”. Organizers: Prof. Oriol Guasch and Prof. Laurent Maxit.

The six papers were presented by GTM researchers Dr. Marc Arnela, Prof. Oriol Guasch and Dr. Jie Deng from the acoustics research line and by Prof. Francesc Alías from the signal processing line. Those works were performed in collaboration with the GTM researchers Dr. Arnau Pont and Carme Martínez-Suquía from the acoustics line, and Ferran Orga, Dr. Rosa M. Alsina-Pagès and Dr. Joan Claudi Socoró from the signal processing line. Find listed below the complete list of publications.
