In this talk, we will present photoacoustic spectroscopy, its basics and advantages. This technique can be used on gas sensing developments, and the applications are numerous and varied. Here, we will focus on the measurement of atmospheric pollutants and their impact on health. This impact can be assessed through the analysis of exhaled air, using specific biomarkers. We will show that breath analysis can also be a key detection technique in medical diagnosis. This work is being carried out in collaboration between Montpellier University and Montpellier University Hospital.
Bio: Dr. Aurore VICET is a professor in Montpellier University, France, in charge of spectroscopic developments based on tunable lasers: study and characterization of single frequency semiconductor lasers for spectroscopic applications, study and development of laser systems based on photoacoustic techniques in the infra-red, Laser/LED Quartz Enhanced Photoacoustic Spectroscopy, Si-based oscillators and MEMS.The applications fields of her research are pollutants evaluation in environment and medical diagnosis.
Emerging topics in audio signal processing: ecoacoustics, urban acoustics, industrial acoustics, medical acoustics
Ethology, ecology, urban geography, industrial engineering, and biomedical engineering are all disciplines that value sound as information. Long limited to speech and music signals alone, audio signal processing is finding compelling applications for instrumentation in these disciplines. In turn, it is fueled by new challenges in fundamental research. This is evidenced, among other things, by increasingly autonomous and adaptive in situ acoustic sensors; a revival of statistical and geometric methods for time-frequency; and the invention of analysis and synthesis techniques based on unsupervised or minimally supervised learning.
It is in this context that we intend to provide a progress report on work on sounds other than speech and music. These « emerging topics » include, but are not limited to, ecoacoustics, urban acoustics, industrial acoustics, and medical acoustics. The invited speakers will provide an overview of the main issues inherent in these fields while striving to be accessible to the IASIS community as a whole. Furthermore, the call for talks and posters will allow for more specific areas of ongoing research to be addressed.

Studies about the *Soundscape* started in the sixties with the work of Murray Schafer originally developed in a musical frame. Debates during 50 years converge to a chaired definition of this concept in 2014. In this presentation, I will de

Sound design is a relatively recent field of design, based on an approach that aims to consider the sound component right from the design phase of an object in order to make an intention audible; or, to put it another way, and to quote Loui

The speed of global change keeps increasing bringing up dramatic turn over of species assemblages. This can lead to modified ecosystem functions such as changes in pollination rates or seed dispersion. These functions require close monitori
