Academic Background

Thibaud Necciari studied electrical engineering at the “Superior Institute of Electronical and Digital Technologies” (ISEN) in Toulon, France. He graduated in 2006. The same year, he completed a Master's Degree in signal processing at the University of La Garde, Toulon (Master thesis: “Design of an analysis-synthesis interface of impact sounds based on physical and perceptual attributes of real sounds”). In October 2006, he obtained a doctoral grant from the French Ministry of Research. His PhD thesis in Acoustics, “Time-frequency masking: Psychoacoustical measures and application to the analysis-synthesis of sound signals” (University of Provence, Marseille, France), was publicly defended in October 2010. A particularity of this study was its multidisciplinarity because it required knowledges in both the psychoacoustics and signal processing fields. The research was conducted at the Laboratory of Mechanics and Acoustics, CNRS (“National Center for Scientific Research”) in Marseille, France, and the Acoustics Research Institute, Austrian Academy of Sciences.

Current Research

Since November 2010, T. Necciari is part of the “Mathematics and Signal Processing in Acoustics” group at the Acoustics Research Institute. He is interested in time-frequency representations, analysis-synthesis and processing of sounds. More specifically, he currently searches to match the time-frequency representations of sound signals to human auditory perception by exploiting masking phenomena in those representations. In other words, can we see what we hear? Applications of such an approach are, for instance, audio analysis-synthesis tools and perceptual audio codecs. T. Necciari is also part of the "Psychoacoustics and Experimental Audiology Group" where he pursues his work on auditory masking. Additional research topics include: auditory modeling, effects of auditory efferents on the peripheral processing of sounds, and decision mechanisms in sound detection and recognition.


T. Necciari is a member of the French Society of Acoustics (SFA) and the Institute of Electrical and Electronics Engineers (IEEE).
