In the project Sons al Balcó, we aim to study the effect of lockdown due to ... -
Methodology description of a real-environment commercial farm to analyse cattle vocalisations
(Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2023-09)Animal welfare is an essential concern for our society. Now, various studies show that animal welfare also has an impact on the growth and the reproductive potential of animals, as well as on their ... -
The european project "Deuteronoise" - characterization of maritime noise in different european basins and its impact on ecological relevant deuterostome invertebrates
(Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2025-09)DeuteroNoise is an European project founded by JPI Oceans intergovernmental platform. The project aims to characterize the noise pollution caused by maritime traffic in selected sites of the North ... -
Effects of controlling chaotic vocal fold vibrations on finite element generated vowels
(Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2023-09)Lumped mass models of the vocal folds have been widely used to analyze the physics of human phonation. This is a strongly non-linear process that results in regular self-oscillations of the vocal folds. ... -
Influence of a realistic human head on the directivity of vowel /a/ based on three-dimensional finite element simulations
(4 p., 2023-09)The human voice can be accurately simulated using three-dimensional (3D) finite element simulations. These simulations involve the generation of sound waves from the vocal cords, their 3D propagation ... -
Gaussian series solution for sonic black holes in duct terminations
(Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2023-09)Acoustic black holes (ABHs) at the end of duct terminations slow down impinging waves by means of a set of rings separated by cavities, whose inner radii diminish following a power law profile. Energy ... -
Experimental study of the influence of a rectangular vocal folds inclusion on their auto-oscillation
(Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2023-09)Vocal folds auto-oscillation is the result of a fluid-structure-acoustic interaction within the larynx. -
Measurement of the sound absorption coefficient of materials in a reverberant chamber using an omnidirectional parametric loudspeaker
(Proceedings of the 10th Convention of the European Acoustics Association Forum Acusticum 2023, 2023-09)The omnidirectional parametric loudspeaker (OPL) is a sound source that exploits the phenomenon of the parametric acoustic array (PAA) to produce an omnidirectional sound field. It consists of hundreds ... -
Flat and cuverd parametric acoustic loudspeakers measured with exponential sine sweeps
(Proceedings of the 11th Convention of the European Acoustics Association Forum Acusticum 2025, 2025-06)Parametric Acoustic Loudspeakers (PALs) utilise ultrasounds to generate an audible field thanks to a non-linear effect in air. This phenomenon is difficult to simulate, so an alternative is to rely on ... -
