|Title:||Design considerations of building elements for traffic and aircraft noise abatement|
|Keywords:||Traffic noise;Aircraft noise;Dry wall constructions;Acoustics|
|Abstract:||The paper presents various design aspects based on exhaustive review of previous studies done so far and presents a database and design aspects of sandwich material combinations for applications in building elements, including various wall and roof constructions to combat traffic and aircraft noise. The paper includes a series of laboratory experiments carried out in Reverberation chambers at NPL for characterizing the sound insulation properties of sandwich dry wall partition panels in conjunction with the laboratory results published on masonry and drywall sandwich constructions by various researchers. The work provides an extensive database and physical understanding of theoretical phenomena proposed in previous studies for design and development of better sound insulative sandwich drywall constructions for their applications in building facades, walls, ceilings and doors for abatement of traffic and aircraft noise in Delhi city and tries to assimilate all the design guidelines in a cause and effect analysis diagram. The present work also envisages the significance and need of stricter building regulations w.r.t sound insulation of building elements for new residential projects planned especially in vicinity to airport or road traffic in India.|
