Embodiment Construction

[0010] Such as figure 1 and figure 2 As shown, the present invention includes: two layers of glass 1 and 2, micro-perforated plate 3, muffler air duct 4, ventilation fan 5, air inlet 6, air outlet 7, two layers of glass 1, 2 inside and outside the window, two There are two micro-perforated plates 3 processed from transparent materials inside the layers of glass 1 and 2 to form a micro-perforated plate cavity noise reduction structure. Between the two micro-perforated plates 3 is a sound-absorbing air duct 4, through which the airflow passes. 4, the cavity structure of the micro-perforated plate 3 absorbs the noise in the airflow. A ventilation fan 5 and an air inlet 6 are arranged above the muffler window, and a filter screen 8 is provided. The air outlet 7 is arranged below the muffler window, and is provided with a movable small window 9 which can be opened / closed. Or a sound-absorbing material 10 is provided in the air inlet 6 and the air outlet.

Abstract

All translucent ventilation and sound-deadening window comprising two-layer glass, microperforated panel, sound-deadening air duct, an air renewal draught fan, air admission port, air vent, wherein the two-layer glass is arranged inside and outside the window, two microperforated panels of transparent material are arranged inside the two-layer glass to form microperforated panel cavity sound-deadening arrangement, between the two microperforated panels is a sound-deadening air channel, the sound-deadening window includes an air renewal draught fan and an air admission port on the upper portion, the air vent is arranged beneath the sound-deadening window.

Description

technical field [0001] The invention relates to an anechoic window, in particular to a fully transparent and ventilated anechoic window, which belongs to the field of noise control in environmental engineering. Background technique [0002] The problem of noise control has been paid more and more attention by people. Environmental noise is directly related to people's quality of life, and even has an important impact on people's physical and mental health. With the increasing degree of urbanization, people are constantly pursuing the convenience and speed of transportation. There are more and more urban rail transit, elevated roads, expressways, and maglev express transportation. These facilities not only bring convenience to people, but also It has caused increasingly serious environmental noise pollution, and now traffic noise has become the most important noise pollution problem in cities. On the other hand, the land value in the areas on both sides of the trunk line is ...
