Introduction

GB/T 19889 "Site Measurement of Sound Insulation of Buildings and Building Components" covers the use of sound pressure measurement methods to determine the sound insulation of buildings and building components. The on-site measurement method for airborne sound insulation performance aims to standardize and guide the arrangement of on-site sound insulation measurements in buildings, ensuring the accuracy of the measurements. To the point of being responsive. GB/T 19889 is proposed to consist of three parts. ---Part 1.Airborne Sound Insulation Between Rooms. The purpose is to provide on-site examples of airborne sound insulation between two rooms in a building. Measurement methods. ---Part 2.Impact Sound Insulation. The purpose is to provide on-site measurement methods for impact sound insulation of buildings. Note. GB/T 19889.7 specifies the field method for determining the impact sound insulation of buildings using the sound pressure measurement method. The revised GB/T 19889.7 will adjust the standard... The serial number is Part 2 of this series. ---Part 3.Exterior Wall Components and Airborne Sound Insulation. The purpose is to provide sound insulation for building exterior wall components and airborne sound insulation. On-site measurement methods.

1 Scope

This document describes a method for determining the airborne sound insulation performance of exterior wall components (component method) and the entire exterior wall (exterior wall method) using the sound pressure method. This document applies to measurements in the frequency range of 50Hz to 5000Hz in rooms with a volume of 10m³ to 250m³. The test results can be used to quantify, evaluate, and compare airborne sound insulation performance, regardless of whether there is furniture in the room or whether the sound field approximates diffusion. The measured airborne sound insulation performance is frequency-dependent, and it can be converted into frequency using the methods given in GB/T 50121 and ISO 717-1. A single-valued evaluation metric characterizing acoustic performance. The component method is used to determine the sound insulation of exterior wall components, such as windows. The most accurate component method uses a loudspeaker as an artificial sound source and employs on-site... Using traffic noise as a sound source results in slightly lower measurement accuracy. The exterior wall method aims to determine the sound level difference between outdoor and indoor areas under actual traffic conditions. The precise exterior wall method utilizes actual traffic noise as a sound source. When the traffic noise level received indoors is insufficient, loudspeakers are required. Artificial sound sources are used. Table 1 provides an overview of these methods.

The sound insulation measurements (for all parts) are compared. This is used to evaluate the laboratory sound insulation performance versus the field sound insulation performance of exterior wall components. When dealing with relationships, this method is the preferred approach. ...
