Provision of Required Acoustic Condition in Premises due to the Use of Gypsum Tongue-and-Groove Slabs

Increased noise is a harmful physical factor of the environment, the impact of which on people under certain conditions can lead to disease or persistent decline in working ability. The Lr level index was chosen as the numerical value of noise in order to determine the degree of irritation as regard to the public masses. The level of evaluation is defined in ISO 1996-2. This parameter is the value of noise exposure, adjusted with due regard for known factors that increase the degree of irritation. The main parameter is the A – weighted equivalent of the level of continuous sound pressure. The main construction and acoustic protection measures against noise are sound insulation, sound absorption and noise screening. In specific cases, these methods can be implemented using gypsum tongue-and-groove slabs. “Technical Institute of Certification and Testing” Close Corporation (Minsk) together with OJSC “BELGIPS” has conducted the studies of sound-insulating ability of single- and double-layer partitions of different designs from gypsum tongue-and-groove slabs faced with moistureresistant gypsum plasterboard sheets (MRGPS) and without facing. Increasing the sound insulation properties of the partition is achieved due to the correct architectural and planning solutions, increasing the density and weight of the gypsum board respectively, increasing internal losses in the double partition. In this case, the sound insulating ability of double-layer partitions of different designs from gypsum tongue-and-groove slabs should be determined only by instrumental way.
