Abstract
The invention relates to a window, in particular to a soundproof window which not only maintains ventilation, but also insulates sound. The soundproof window comprises a front glass sheet and a rear glass sheet, wherein the front glass sheet and the rear glass sheet are fixed in a frame at certain spacing, and the front glass sheet and the rear glass sheet are provided with a plurality of small holes. The spacing of adjacent surfaces of the front glass sheet and the rear glass sheet is less than or equal to 5 centimeters. The aperture of each small hole on the front glass sheet and the rear glass sheet is less than or equal to 1 centimeter. The hole pitch between small holes on the front glass sheet and the rear glass sheet is less than or equal to 5 centimeters. The soundproof window can not only effectively isolate the outside noise, but also ensure the flow of outside air and indoor air, and the freshness of the indoor air.
Description
technical field [0001] The invention relates to a window, in particular to a soundproof window capable of maintaining air circulation and soundproofing. Background technique [0002] At present, with the progress and development of human society, people pay more and more attention to environmental protection, and environmental governance has become the top priority of our current work. Noise pollution is a part of environmental pollution, and its negative impact on human health has become a common knowledge. [0003] Theoretically speaking, the propagation of noise can be divided into three stages: noise source, transmission path and receiver. Therefore, the control of noise pollution must start from the above three aspects. It should be said that reducing the sound source is the most fundamental aspect of noise control, and people have also taken corresponding measures, such as using low-noise equipment and improving processing technology. However, due to economic reason...
