Sound insulation layer structure

This creation is about a sound insulation layer structure, and especially about a sound insulation layer structure that can reduce the impact sound of the floor slab.

With the development of social urbanization, residences have also evolved toward concentration and high-rise development, so that the prevention of noise problems of collective residences has become one of the major tasks to improve the quality of the living environment. There are many types of residential environment noise, including the noise generated from the outdoor environment or the use of people in nearby buildings. The noise is introduced into the room through doors, windows, walls, floors, etc., and the noise emitted by construction equipment constitutes a building noise environment.

In the early days, the Ministry of the Interior’s Construction Department’s regulations on noise control were based on the conditions of enumerated building sound insulation materials, thickness, etc., and could not cover all building materials and construction methods. In recent years, China has successively completed the revision and publication of acoustic standards, and the Institute of Architectural Research of the Ministry of the Interior has completed the investigation and diagnosis mechanism of the domestic residential acoustic environment status in 1998-99. Measurement and diagnosis evaluation, preliminary accumulation of domestic basic data, as a basis for building sound insulation performance and legal basis.
