Abstract
This paper presents evaluation of vibroacoustical requirements in the context of impact and airborne sound insulation in hotel building. This building represents traditional wooden architecture present in southern Poland. Similar structures can be found all around Europe in mountainous areas. Due to fact that there are little information about acoustic conditions of such buildings, this paper gives measured values of sound insulation of typical solutions used in this architecture. In order to define if requirements of current polish standard PN-B-02151-03:2015 for hotel buildings are met, impact sound level and airborne sound insulation of representative partitions were measured. Measurement conducted in presented building shows issues connected with non-sufficient airborne sound insulation of internal partitions – timber log walls. Due to its low mass and, in simplification, homogenous structure, its sound insulation is far from meeting requirements. Considering timber structural ceiling and reinforced concrete floor present in hotel building requirements of impact sound level and airborne sound insulation are met. The solution of weak acoustic conditions of walls is proposed as plasterboard pre-wall with mineral wool inside.
Highlights
IntroductionBefore discussion, it has to be stated what comfort means
In measurement process 8 partitions were tested for airborne sound insulation and 4 partitions for impact sound level
Basing on results obtained from measurements conclusions as stated below can be made: 1) Timber floor system with timber flooring is sufficient to provide acoustic properties required by polish standard [11]
Summary
Before discussion, it has to be stated what comfort means. On behalf of this paper, comfort is defined as fulfillment of given standards requirements using Single Number Quantities (SNQ). Opening discussion about acoustic requirements for dwellings and hotels is worth to state that used (SNQ) are justified in scientific society [1,2,3] for airborne sound insulation and [4,5,6] for impact sound level. Considering measurements of airborne sound insulation, difference of levels is measured and taking into account impact sound level, only sound level from impact is measured
