Key takeaways
Sources of aerodynamic noise are multiplying and can disturb local residents and biodiversity.
To anticipate the noise generated by these sources (drones, wind farms, etc.), researchers are attempting to characterise and model the sound they emit.
The difficulty is that the intensity of the sound from a wind farm varies enormously depending on several parameters (type of ground, meteorological fluctuations, shape of the blades, etc.).
Numerous technical solutions for reducing the decibel level of wind turbines are under study or have already been implemented.
Sometimes, limiting noise pollution from a device goes hand in hand with optimising its performance, such as the speed of a drone or the output of wind turbines.

Key takeaways
Binaural sound is a method of sound diffusion that enables 3D sound to be recreated virtually.
Coupled with a head-tracking system, binaural sound can indicate direction independently of the orientation of the head, thus becoming a high-performance guidance tool.
This high-performance guidance tool could be used in a variety of contexts (sports or tourism) and by everyone (visually impaired or not).
Currently under development, this project could eventually be used by everyone by integrating with navigation applications and listening devices already on the market.
Based on our morphology and the natural functioning of the brain, the binaural sound system is intuitive and requires no new learning.
Ircam Amplify is a commercial subsidiary of Ircam set up to meet the growing demand from companies for sound products.
Sound plays an increasingly important role in everyday life, not least because it is associated with the management of man-machine interfaces and enables users to find their way around.
The SpeaK method was developed by Ircam to characterise sounds and expand the sound vocabulary.
According to one study, sound can have a 40% influence on a consumer’s intention to buy.
Sound influences purchasing behaviour, road safety and the user experience, requiring particular attention in product design.
