Internal Soundproofing Buildings Isolated by Elastomeric Links from Externally Induced Vibration
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2012, Vol 9, Issue 2
Abstract
Interior soundproofing is a requirement for buildings with special activities where the level of vibration and noise shall be minimal. This paper specifies the essential requirements for the definition of performance vibration isolation from the outside of buildings for special purposes. This category includes operating rooms, facilities and premises of "white rooms", rooms processing, calibration and mounting the semiconductor where the level of vibrations from the urban environment and/or industry should be below the allowed threshold. In this context, we detail the dynamic model of a building placed on elastomeric elements for which are set the physical and geometric conditions by decoupling and reduction their frequency in ratio 1/4 .... 1/6 of the excitation frequencies. Also, are set the equations of motion for the externally excited system in order to evaluate the level of forced vibrations.
