Objectifs


Contenu

Day 1 (Monday, January 6th, 2020)
8h30-12h30 What is a sound signal I? (N.Mathevon & F.Sebe)
Acoustic waves, digital acquisition, amplitude and measuring dB
13h30-15h30 What is a sound signal II? (N.Mathevon & F.Sebe)
Time/frequency representations, acoustic parameters, sound propagation, filters
Short introduction to classical softwares (Goldwave, Praat, Avisoft, seewave)
16h-20h Students’ projects warm-up (D.Reby, N.Mathevon & F.Sebe)
Groups of 5 students (material: their own phones and/or computers + free apps)
Examples of possible projects:
- The campus soundscape. I- the noise. (objective: mapping the variation of intensity level on the La Métare Campus
–in and out the classrooms; method: recording + measuring the dB level of the background noise with phone apps at different
hours and locations on the campus + characterizing the entropy and biodiversity indexes
- The campus soundscape. II- Biodiversity. (objective: mapping the acoustic diversity on the La Métare Campus;
method: recording the soundscape with phone apps at different hours and locations on the campus + characterizing the
entropy and biodiversity indexes
- The circadian rhythm of voice pitch (objective: testing if the pitch of an individual’s voice changes during the day;
method: recording of students’ voices at different moments during the day + psycho-acoustic tests to evaluate if we’re
sensitive to theses changes in voice “Please tell when during the day this voice has been recorded”)
- Voice features and individual size (objective: testing how voice pitch and spectrum depend on an individual’s size ;
method: recording students’ voices + measuring their size & correlates + psycho-acoustic test to see if we’re able to assess
the size of an individual from her/his size –confounding effect = sex)
- Politicians’ voices and election issues (objective: is it possible to predict the issue of an election from vocal features
measured during a political debate?; method: analysis of recordings –political debates available on the net- + psychoacoustic
tests of students?)
- Lombard effect (objective: do we modify the amplitude of our voice depending on the level of the background noise –
methods : playback of noise of different levels through headphones + recording of speech + measure of amplitude)
- Characterizing a loudspeaker for a biacoustics experiment (objective: determining which is the best
loudspeaker for an experiment on woodpecker drumming – methods: playback of white noise + woodpecker drummings in the
sound-proofed chamber + comparison with original signals)
- …
Students’ expected production:
*Poster (1 page) : Scientific context, problematic, hypothesis, method, results, discussion
*Powerpoint (15 minutes max).
