Effect of vibrations on historic buildings: an overview

Although sound transmission data for many types of windows have been published, the results of different studies are not in close agreement. Discrepancies are apparently due to the properties of the samples themselves and the laboratories in which they were tested. The paper commences with a description of a variety of window properties and laboratory characteristics that can affect transmission. In an effort to obtain further information on sound transmission loss of single and double glazed windows, an extensive series of measurements were conducted to determine the dependence of transmission loss on glass thickness and interpane spacing. As many variables as possible were held as constant as was practicable. This paper describes the experimental conditions including the test environment and window mounting, the test procedure and the experimental results for single and double glazing.Bien que des donn\ue9es de transmission du son aient d\ue9j\ue0 \ue9t\ue9 publi\ue9es pour de nombreux types de fen\ueatre, les r\ue9sultats des \ue9tudes effectu\ue9es ne font pas l'unanimit\ue9. Les \ue9carts constat\ue9s sont sans doute dus aux caract\ue9ristiques des \ue9chantillons et \ue0 celles des laboratoires dans lesquels ils sont soumis aux essais. Cet article fournit une description des caract\ue9ristiques d'un certain nombre de fen\ueatres et des laboratoires qui peuvent influencer la transmission du son. Afin de recueillir des donn\ue9es suppl\ue9mentaires sur la perte de transmission du son de vitrages simples et doubles, une s\ue9rie de mesures ont \ue9t\ue9 prises pour d\ue9terminer l'influence de l'\ue9paisseur du vitrage et e l'espace entre deux vitrages sur la perte de transmission du son. Le plus grand nombre de variables possibles ont \ue9t\ue9 maintenues constantes. Cet article d\ue9crit les conditions qui pr\ue9valaient lors des essais, incluant les laboratoires d'essai et la description des fen\ueatres, les proc\ue9dures et les r\ue9sultats des essais r\ue9alis\ue9s sur des vitrages simples ou doubles.Peer reviewed: YesNRC publication: Ye
