Unmanned aerial vehicles (UAVs) are currently being used for reconnaissance missions, tactical surveillance, and infrastructure inspection. When legislation allows it, these devices will provide additional services close to inhabited areas, which could lead to noise complaints. On most UAVs, the propellers are the dominant source of noise. As a res...
Electric vehicles (EVs) constitute an increasing share of the vehicle fleet, in particular regarding light vehicles. This ratio may be significantly enhanced in urban areas that favour access to low-emission vehicles. Acknowledged to be quieter than conventional vehicles due to a lower propulsion noise, EVs feature a comparatively heightened tyre-r...
The influence of the ground and atmosphere on sound generation and propagation from wind turbines creates uncertainty in sound level estimations. Realistic simulations of wind turbine noise thus require quantifying the overall uncertainty on sound pressure levels induced by environmental phenomena. This study proposes a method of uncertainty quanti...
Contexte - Les lignes directrices de l'OMS relatives au bruit environnemental soulignent que les preuves concernant les effets sur la santé du bruit émis par les éoliennes sont soit inexistantes soit de faible qualité. Dans ce contexte, une étude de faisabilité a été conduite en France en 2017. Objectif - L'objectif était de proposer une méthodolog...
Background: Although several cross-sectional studies have shown that aircraft noise exposure was associated with an increased risk of hypertension, a limited number of longitudinal studies have addressed this issue. This study is part of the DEBATS (Discussion on the health effect of aircraft noise) research program and aimed to investigate the ass...
In regard to the mitigation of environmental noise across major industry sectors, the present study focuses on the numerical prediction of passive noise reduction devices. Here, it is further explored how the noise attenuation induced by locally reacting noise absorbing materials (also called acoustic liners) can be simulated using a time domain hi...

The use of different noise annoyance scales across studies and socio-acoustic surveys, in particular the popular 5-point verbal and 11-point numerical scales, has made the evaluation, comparison, and pooling of noise annoyance responses among studies a taxing issue. This is particularly the case when “high annoyance” (HA) responses need to be compa...
La présentation effectue une synthèse des modèles d'émission sonore de la méthode prévision CNOSSOS-EU pour sa mise en oeuvre dans le contexte français, notamment concernant les véhicules semi-lourds. La question de l'émission sonore des véhicules électriques dans les modèles de prévision est également évoquée.
