Abstract

A bidirectional composite soundproof curtain belongs to the environmental protection field. The bidirectional composite soundproof curtain relates to a device which can prevent outdoor noise from going into a room as well as can prevent indoor noise from leaking outdoors, and can effectively attenuate the indoor and outdoor noise from under the condition that indoor and outdoor air convection is not affected by opening a window for ventilation, so the curtain is bidirectional; and the curtain is designed based on a noise elimination technology, a sound absorption technology and a sound insulation technology, so the curtain is named as the bidirectional composite sound proof curtain. At present, most of the methods for controlling urban noise pollution still keep at the administrative intervention. The invention aims at providing the soundproof curtain which establishes a sound barrier between noise sources and the room, thus providing cellular governance for an individual.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and more specifically relates to a device that can prevent outdoor noise from entering the room and also prevent indoor noise from spreading outside. Background technique [0002] With the progress of society and the improvement of people's awareness of environmental protection, people's awareness and requirements for the quality of the environment in work, study and rest are also gradually improving. At the same time, the emphasis on environmental noise pollution is also increasing. At present, in terms of the indoor noise pollution caused by outdoor noise, the control means basically stay in some areas with serious noise pollution to build sound insulation barriers or use insulating glass sound insulation technology. However, the construction of sound insulation barriers is not only restricted by land and space, but also by municipal and city appearance and other factors. Alth...
