This document was first published as GB/T 19889.2-2005 in.2005, and this is the first revision.IntroductionMeasurement of Sound Insulation in Buildings ISO 140 (all parts) Measurement of Sound Insulation in Acoustical Buildings and Building Elements has been revised and the standard number has been changed and standard names. Among them, the original standard number and standard name of the relevant parts related to laboratory sound insulation measurement are changed to ISO 10140 (all parts) "Laboratory Measurement of Sound Insulation of Acoustic Building Components" is divided into five parts; the original standard number and standard name of the relevant parts involving on-site measurement have been changed. It is ISO 16283 (all parts) "On-site measurement of sound insulation of acoustic buildings and building components", which is divided into three parts; originally related to the uncertainty of sound insulation measurement The standard number and standard name of Part 2 of the degree have been changed to ISO 12999-1 "Evaluation and application of uncertainty in measurement of acoustics in acoustic buildings - Part 2".

Corresponds to ISO 10140-4.The purpose is to provide a laboratory for measuring the void space of building components Basic measurement techniques and test procedures for air and impact sound insulation. For many problems in architectural acoustics, it is necessary to adopt a clear and practical method to evaluate the measurement uncertainty. only By fully evaluating the measurement uncertainty of the relevant quantity, it can be determined whether the relevant quantity meets the specified requirements and whether the laboratory can provide the correct measurement Results or whether one product has better acoustic performance than other products. For the evaluation of measurement uncertainty, the first choice is the method specified in GB/T 27418 or ISO /IEC Guide 98-3 (abbreviated as GUM). method) to be assessed. The GUM method specifies a method for evaluating measurement uncertainty based on a complete mathematical model of the test procedure, i.e. The weighted contribution of the degree component evaluates the measurement uncertainty. However, as far as the existing technology is concerned, it is difficult to mathematically construct all the different quantities in the sound insulation of buildings. mold. Therefore, this document only gives the principle of using this uncertainty assessment method. In order to solve the problem of uncertainty evaluation of sound insulation measurement, the concept of reproducibility and repeatability is introduced in this document, which is also the medium of sound insulation measurement in buildings. The traditional uncertainty assessment method. The concept is to assess the uncertainty of measurement methods and measurement results based on interlaboratory comparison of measurement results. degree offers the possibility.
