There are now no less than 42 curated lists of academics on Mastodon, in various subject areas, on this GitHub, as well as links to groups, preprint and bibliography bots, and servers/communities. Check it out, tell others about it, and bookmark it for future reference! https://github.com/nathanlesage/academics-on-mastodon

Because this was my only post ever that got +5k likes on Twitter, it is only fitting that this is my first post here ⤵️
I created an awesome-PhD list on GitHub where everybody can contribute with their own tools and resources! 🔥
✨ Check it out and contribute yourself via pull requests: https://github.com/helenahartmann/awesome-PhD ✨

Hello World! We're here to reach the #acoustics community on mastodon - Researchers, academicians, clinicians, practitioners, educators, students, and anyone with an interest in acoustics! Follow for acoustics news and updates.

Facebook (sorry: Meta) AI: Check out our "AI" that lets you access all of humanity's knowledge.
Also Facebook AI: Be careful though, it just makes shit up.
This isn't even "they were so busy asking if they could" --- but rather they failed to spend 5 minutes asking if they could.
Et voilà! please feel free to ask me if you want more details on any of these projects! (9/9)
The two remaining projects are from the IRCAM’s side. Emmanuel Ponsot is investigating the integration of spectral and temporal information by the auditory system. He also received a funding for a project looking for early markers of cochlear synaptopathy. (8/X)
In parallel, Monica Hedge is exploring similar questions on infants of 6 months or 10 months, as part of her PhD project (7/X)
The Université Paris Cité team, led by Laurianne Cabrera, is mainly interested in the auditory development during childhood and infancy. In this project, Irene Lorenzini and Charlotte Benoit try to relate the maturation of AM processing in 5- to 11-year old children to the improvement of speech in noise perception during this period of life. (6/X)
The Auditory Classification Images project is actually the follow-up of my PhD work from 10 years ago. We develop new methods to investigate auditory perception, using a microscopic trial-by-trial analysis (aka "revcorr") of the participant’s responses. We apply this approach to the study of phoneme categorization, AM detection, and sentence segmentation. (5/X)
This very crowded slide details the Human Auditory ecology project led by Christian Lorenzi, investigating many aspects of the perception of natural soundscape by humans, from the detection of biophony (e.g. birdsongs) to the design of an algorithm for synthesizing natural soundscapes
At the core of the Modulation group is the notion of computational modelling of auditory processing. In almost all our projects we use artificial listeners as a baseline to compare/predict/interpret the results of human participants. We also contribute actively to the Auditory Modeling Toolbox project (https://www.amtoolbox.org/), which provides open-source models for many stages of the auditory system. (3/X)
@cognition @psycholinguistics The Modulation Group brings together researchers from 3 institutions in Paris: l'Ecole normale supérieure, Université Paris Cité and Ircam. (2/X)
I am preparing a presentation about the ongoing projects of our research team in Paris, and I realized that it may be worth sharing as a thread as an #introduction for the @cognition #audition @psycholinguistics community in the #academicmastodon ⬇️
Reminder: the Department of Cognitive Studies at Ecole Normale Supérieure de Paris is inviting applications for a *fully-funded* extended 3-year Masters program in Cognitive Science, which offers interdisciplinary training in Linguistics, Philosophy, Cognitive Social Science, Psychology, Neuroscience, Modeling and Cognitive engineering (https://cognition.ens.fr/en).
Deadline for applications: December 7

Mais pourquoi l'IA est-elle aussi méchante (dans les livres, les films et les jeux) ? Vendredi 9 décembre de 10h à 12h à l'Inria Bordeaux avec Natacha Vas-Deyres, Laurent Queyssi, Fabrice Carré et Nicolas Roussel. Entrée gratuite.
Christine Petit et Paul Avan chez La Science #CQFD @franceculture pour une discussion approfondie des différentes formes de déficit auditif et de leur remédiation. https://www.radiofrance.fr/franceculture/podcasts/la-science-cqfd/surdite-etre-tout-ouie-9736794
@jesswade Very appealing idea, I'd love to do the same for our master program in Paris... In practice how do you evaluate this criterion during the interview? #AcademicMastodon #ScienceMastodon
Then we analysed how well auditory neurons along the ascending auditory pathway were able to track slow changes of the sounds temporal envelope. The answer is: pretty well in general. Figure below shows the correlations in the original condition between peri-stimulus time histograms (PSTHs) of subcortical and cortical recordings and the stimulus envelope, both filtered in three selected AM ranges (slow fluctuations, medium fluctuations, fast fluctuations).
In a nutshell: Samira did a fantastic job recording neuronal activity from six different levels of the auditory system from auditory nerve up to secondary auditory cortex in anesthetized guinea-pigs, in response to many different types of degraded stimuli: vocalizations from other guinea-pigs, either in quiet, vocoded (with various resolutions), in a stationnary noise or a more natural noise (at various SNRs)
New paper published in the Journal of Physiology by Samira Souffi, JM Edeline, Brice Bathelier, Chloé Huetz, and myself: "Reduction in sound discrimination in noise is related to envelope similarity and not to a decrease in envelope tracking abilities" https://physoc.onlinelibrary.wiley.com/doi/epdf/10.1113/JP283526
