Foreword

The standard insulation performance test method main reference ISO 140-3.1995 "Acoustics --- Noise measuring buildings and building components Amount --- Part 3. building elements Laboratory measurements of airborne sound insulation ", this standard amount of noise detection method and ISO International Standard Consistent approach. This standard replaces GB/T 16730-1997 "building sound insulating properties door air classification and detection methods" and GB/T 8485- 2002 "of windows airborne sound insulation performance classification and test methods." This standard and GB/T 16730-1997, GB/T 8485-2002 compared to the main changes are as follows. --- The above two criteria together as a standard, entitled "Building doors and windows of airborne sound insulation performance classification and test methods"; --- Provisions were graded index value outside doors and inner doors and windows, insulation performance unified hierarchical order windows and doors, this standard "1" Noise level is the lowest level of performance, this is consistent with the standard GB/T 8485-2002 of hierarchical order, with the GB/T 16730-1997 Grading the reverse order (GB/T 16730-1997 in "Ⅰ" level is the highest level of sound insulation performance), this standard with the original standard interval Sound Performance classification table are listed in Appendix C of this standard; --- Rating index value, the introduction of noise spectrum correction amount using weighted sound reduction and the correction amount of traffic noise spectrum and as exterior doors Window grading index value using weighted sound reduction and pink noise spectrum and the amount of correction of the classification as internal doors index value; --- When computing the average of three specimens jamb insulation performance, the use of energy substitution averaging original standard arithmetic average method; --- Specifies the interstitial wall insulation requirements, with reference ASTME90-04, increased interstitial wall indirect sound transmission and impact test Fixed content is attached as Appendix A. Appendix A of this standard is a normative appendix, Appendix B and Appendix C are informative appendices. The standard proposed by the Ministry of Housing and Urban-Rural Development of the People's Republic of China.

3 Terms and Definitions

The term and the following terms and definitions GB/T 3947 and GB/T 5823 established in this standard applies. 3.1 Sound power transmitted through the specimen and the ratio of incident to incident acoustic power of the specimen on the formula (1). τ = WτWi (1) Where. Wτ --- transmitted through the specimen sound power in watts (W); Wi --- sound power incident on the incident on the specimen, in watts (W). 3.2 Sound power incident on the specimen and the transmission ratio of the transmission power of the sound specimens, taking the logarithm of base 10 multiplied by 10 decibels (dB). Sound insulation and sound transmission coefficient τ R has the following relationship. R = 10lg1τ (2) τ = 10-R/10 (3)
