Sound insulation system of acoustic sensitive room

Abstract

The invention belongs to the field of construction engineering, and discloses a sound insulation system of an acoustic sensitive room. According to the technical scheme, a sound insulation inner layerroom is arranged in an outer layer encircling structure in a sleeving mode; the sound insulation inner layer room is flexibly connected with the outer layer encircling structure; according to flexible connection, a sound insulation furred ceiling is arranged at the top of the sound insulation inner layer room, a first cavity is formed between the roof of the outer layer encircling structure and the sound insulation furred ceiling of the sound insulation inner layer room; the floor of the sound insulation inner layer room is a floating construction floor; a second cavity is formed between theinner layer wall body of the sound insulation inner layer room and the outer layer wall body of the outer layer encircling structure; and a door opening of the sound insulation inner layer room is horizontally projected into the range of the outer layer wall body and an outer door opening is formed, and a sound insulation door is arranged at the outer door opening. The sound insulation system effectively prevents vibration transmission of sound from the sound insulation inner layer room to the outer layer encircling structure, limits vibration of the sound to a sound insulation inner layer, meets the requirements of high sound insulation, and occupies fewer of the available space of a room.

Description

technical field [0001] The invention belongs to the field of construction engineering, in particular to a building sound insulation system. Background technique [0002] When adjacently arranged acoustically sensitive rooms with high requirements for space privacy and sound insulation are used at the same time, they will interfere with each other. For example, adjacently arranged acoustically sensitive rooms such as music teaching studios and practice rooms often have the need for musical instruments, and They are often arranged to be adjacent to the left and right or up and down, and the requirements for sound insulation are relatively high, so it is necessary to focus on solving the sound insulation problem of the enclosure structure. [0003] The existing conventional sound insulation method is to add sound insulation materials to the wall, top surface and floor of the room respectively. Although it has a certain effect, it cannot completely avoid and eliminate various so...

Problems solved by technology

[0003] The existing conventional sound insulation method is to add sound insulation materials to the wall, top surface and floor of the room respectively. Although it has a certain effect, it cannot completely avoid and eliminate various sound insulation loopholes such as sound vibration and transmission between various materials. , thus unable to meet the requirements of higher sound insulation; or in order to achieve higher sound insulation, aggravate and thicken the building and sound insulation materials, resulting in excessive occupation of the effective use area of ​​the room, increasing the unnecessary amount of building materials, not only Uneconomical and often still less than ideal sound insulation
