PhD Position: Annoyance due to noise and vibrations from railway traffic in cities

 

 

Vibrations due to rail vehicles (e.g. tramway, train) propagate from the tracks to inside neighbour houses. These vibrations can be detected by people but they can also make some panels to move, thus creating noise. In the case of surface transportation these phenomena are associated with the vehicle pass-by noise. This co-exposition to noise and vibration is a source of annoyance, as well as of some health issues.

Few studies have been conducted to investigate this co-exposition in terms of annoyance. They use indices which only describe an amount of energy for each separate exposition. Results can be contradictory. These contradictions could be due to differences in the level or frequency content in the noise or vibration signals used in the experiments. The state of the art shows that more investigations are needed to get a better understanding of this co-exposition. Experiments should be conducted in laboratory as well as in situ in order to bring to light all perceptual phenomena related to annoyance.

 

The goal of the thesis is to improve the knowledge of the perceptual phenomena involved in a combined noise and vibration exposure. Intensity evaluation will be studied, as intensity is well-known to have a key influence on annoyance. As an example, is loudness modified by a simultaneous vibration stimulus? What about the reverse interaction?

First, real signals (measured in buildings) will be analysed. Main temporal or spectral characteristics will be evaluated and their contribution to annoyance will be determined in the case of a single exposition. Then, multi-modal situations will be studied in laboratory, using controlled and real stimuli. These studies will use existing experimental facilities.

 

Supervisors: E. Parizet, Laboratoire Vibrations et Acoustique of INSA de Lyon and C. Marquis-Favre, Laboratoire Génie Civil et Bâtiment of ENTPE, both members of CeLyA (Acoustical Center of Lyon).

 

Job location: Villeurbanne and Vaulx-en-Velin (Lyon area, France).

 

Salary will be consistent with levels in accordance with the upper standards for this position.

The appointment period will be for 3 years (starting by the end of 2015).
