Teresa Bravo has been working on several aspects of sound, vibration and signal processing since her first university degree in Physics Sciences (Universidad Autónoma de Madrid, Spain). Her thesis was mainly concerned with the connections between the physical limitations of control and digital signal processing techniques, both in relation with Active Noise Control in car cabins. After the completion of her PhD, she worked as a post-doctoral research fellow at the Institute of Sound and Vibration Research (University of Southampton, UK) to study the problem of the simulation of random pressure fields in laboratory conditions, and the characterization of the Sound Reduction Index by means of an electroacoustic device driven to reproduce a diffuse field using an array of near-field loudspeakers. She also participated in another research project concerning the implementation of active headrests for personal audio inside airplanes or road vehicles. She joined afterwards the Audio and Communications Signal Processing Group (GTAC) at the Universidad Politécnica de Valencia (Spain), where she considered microphone arrays and beamforming techniques for the characterisation of the properties of reverberant sound fields, and its application to Wave Field Synthesis techniques for the recreation of virtual sound environments. She spent another abroad postdoctoral period at the Acoustic Group of the Departmentof Mechanical Engineering at the Université de Technologie de Compiègne (France) in 2006 to work on a project concerning noise source identification from measurements of the radiated pressure or velocityfield. A flow-duct acoustic facility was designed within the semi-anechoic chamber to show the possibilities of inverse regularized method for the reconstruction of real noise sources. In 2008 she was awarded a Lecture position at the Universidad Politécnica de Madrid (Spain) to work in the Applied Physics department of the Architectural School and in 2009 she obtained a Research Scientist position at the Institute of Acoustics (Madrid), where she carries work concerning vehicle noise control, its characterization and far-field extrapolation, and the study of micro-perforated materials for broadband noise control as an alternative to classical porous material for use in hostile and/or demanding environments.
