JISFA 2 / Environmental Noise and Perceptive approaches
- Adrien Pelat (Laboratoire d’Acoustique de l’Université du Mans, UMR CNRS 6613)
Noise annoyance can be defined in two different ways, depending on whether the sound is listened actively or whether this noise is heard passively. In the first case, the noise can produce an immediate reaction of unpleasantness, linked to its sound signature. In the second case, the noise is not listened to, but suffered. The noise annoyance can then correspond to the short-term disturbance...
In this second presentation, researches that focus on the overall feeling of residents towards their sound environment will be presented. This corresponds to the long-term annoyance. It can only be studied in the field, during surveys. Numerous studies show that this does not simply depend on the exposure of populations to noise, which explains only a third of the annoyance expressed by the...
The comfort of aircraft passengers depends on many factors, including the noise and vibrations passengers are submitted to. Levels can be very high (in helicopters in particular) or more reasonable (large airplanes). In some cases (e.g. engines), the same source is responsible for both sensations. Noise assessment procedures use classical indicators (A-weighted level, possibly penalised...
Focusing on external certification of aircrafts: current procedures, test means evolutions, future regulations at ICAO level.
