Foreword

This code is based on the requirements of the “Ministry of Construction and Revision of 2004 National Standards for Construction and Development of Projects” (Jianbiao [2004] No. 67) issued by the former Ministry of Construction. The "Code for Design of Sound Insulation of Civil Buildings" was revised on the basis of GBJ 118-88.
In the process of compiling this code, the compilation team took into account the noise, sound insulation, and sound absorption of various types of civil buildings collected in recent years, and comprehensively considered the current status of civil buildings, people's acoustic requirements for various types of civil buildings, and socioeconomics. The development level of building acoustics technology, and the development level of building acoustic technology, and on the basis of extensive consultation, the final review was finalized.
This specification is divided into 9 chapters and an appendix. The main technical contents include general rules, terms and symbols, general plan noise prevention design, residential buildings, school buildings, hospital buildings, hotel buildings, office buildings, commercial buildings, and indoor noise level measurement methods. Wait.
The main contents of the revision of this specification are:
1. Added the content of sound insulation and noise reduction design for office and commercial buildings.
2. Appropriate adjustments have been made to the more stringent requirements for the most basic requirements for allowable noise level standards and sound insulation standards in some rooms.
3. The standard value of the indoor allowable noise level is the standard value under the window opening condition in the original specification, and the standard value under the window closing condition in this specification.
The provisions marked with bold type in this specification are mandatory and must be strictly implemented.
