Making use of inexpensive resilient layers like glass or fiber board, or semi-resilient attachments which are inert in nature, will help in reducing the STC rate by two to five decibels. When a sound originates from a source, it travels in all directions through different mediums and strikes objects such as a walls, floors, and ceilings. Thus, more sensitive rooms get a shielding effect. The decrease of window size is limited, as the window size should follow certain rules and regulations. The usage of different wall materials or the usage of different design for the wall would bring variation in the insulating properties of the element. Controlling all aspects of sound entering or leaving a room or building space is the … One such parameter is the sound transmission class(STC). Another way of increasing the insulating property is to add more thickness for the walls.

Another solution is to reduce their use in walls facing noise directly. This is an architectural planning step taken before planning the design of the building. This acts as a parameter to guide an architect to know which material would suit the most, to have an essential acoustic feature by the reduction of noise. It is found that the noise transmission is intercepted when it passes through the walls, floors, windows, ceilings and the building doors. This is both shatter and noise resistant. Metal buildings, which are lighter in weight than a concrete building, for example, have to use different strategies to control sound than mass alone. Our website feature “What’s Your Problem?” is commonly overwhelmed with inquiries about noise and acoustical problems. The arrangement of elements like … This can be an added measure of noise reduction in architectural planning and design. Under such situation, it is always recommended to compromise with the plan and go for an economical and quality construction. Sorry, you do not have permission to ask a question, You must login to ask question. The Proper architectural design may also provide for noise reduction in an area outside of the building. In such cases, measures to reduce direct impact of noise must be carried out. Hence concrete walls are more insulating than wooden walls. When it comes to high-rise, concrete walls are used. Architectural acoustics noise control practices include interior sound reverberation reduction, inter-room noise transfer mitigation, and exterior building skin augmentation.
