Using elastic layers to improve sound insulation in volume based multi-storey lightweight buildings
2009 (English)In: 38th International Congress and Exposition on Noise Control Engineering 2009: INTER-NOISE 2009 ; Ottawa, Canada, 23 - 26 August 2009 / [ed] J. Stuart Bolton, Red Hook, NY: Curran Associates, Inc., 2009, 252-257 p.Conference paper (Refereed)
Lightweight buildings often suffer from poor sound insulation, especially at low frequencies. The volume technique in which sections are being assembled to form a complete building, are well suited for the use of elastic layers in between floors as an action to improve the sound performance.Upon the floor construction's load-bearing beams, one or multiple layers of boards are normally attached. Particle boards and/or plaster boards are installed using screws and/or glue. In the case of using glue solely, there is a potential to improve the sound insulation if glue with elastic properties is used instead of a traditional one which will harden completely.Results from using different kinds of elastic layers between floors as well as different kinds of board glues, all tested on identical constructions, are presented in terms of airborne sound reduction and impact sound pressure level.
