Noise pollution has been recognized as one of the major nuisance and health hazard for an urbanized and industrialized society. The problem becomes more acute in low cost residential flats by the current trend in favour of lightweight structures and the increasing concentration of dwellings in urban areas. The most serious drawback of apartment type of residential buildings is the transmission of sound from one flat to the neighbouring flat. The two fold noise problem are considered in this paper i.e. (i) air borne noise produced by audio visual domestic gadgets and road traffic etc and (ii) impact type of noises produced by footsteps and dropped objects in multistoried apartment dwellings which are transmitted through building structures. In the apartment buildings the acceptable noise levels are governed by Noise Criterion Curve-35 (NC-35) but it has been observed that in most of the cases even NC-45 is not achievable. The reason being inadequate sound insulation provided through doors, windows and partition walls. It is observed that most of the acoustical problems may be avoided by taking into consideration of various acoustical factors in the building design itself. The paper deals with the problem of noise transmission and provision for adequate sound insulation between apartments and other attached dwellings. |
