Description
In order to define appropriate mitigation measures to limit noise and vibration due to railway transportation in residential areas, annoyance criteria have to be precisely defined. In this context, the aim of the VibAcouPhysio project is to explore the potential of physiological measurements to objectivate the perceived annoyance. In a first step, the VibAcouPhysio project investigated the annoyance due to railway noise and vibration in laboratory conditions. A significant correlation was found between physiological metrics, the annoyance evaluated in the questionnaires and the indoor noise and vibration descriptors derived from the noise and vibration signals. In that respect, noise integrates both aspects: air-borne noise (through the façade) and structure-borne noise (radiated by building structure submitted to vibration). The second phase of the project proposes a similar analysis based on in-situ measurements on a few voluntary participants living along railway lines. These measurements include continuous monitoring of physiological, noise and vibration signals, as well as perception surveys several times a day. The participants and their residences have been monitored for a week, day and night, allowing to also address the issue of sleep disturbance. The paper describes the different measurements performed in-situ and proposes a preliminary analysis of the collected data.
