GB/T 19889.5-2006 《Acoustics―Measurement of sound insulation in buildings and of building elements―Part 5: Field measurements of airborne sound insulation of facade elements and facades》 Related products

GB/T 19889.5 - 2006 focuses on the on-site measurement of exterior components and exterior air sound insulation. It specifies the preparation for on-site testing, including the layout of measuring points, etc., to ensure that the test is representative. Clarify the operating specifications and parameter requirements of the required acoustic measurement equipment, and use specific calculation methods to accurately evaluate the acoustic insulation performance of the exterior by measuring the sound pressure level on both sides of the exterior. According to this standard, it can provide reliable data for building acoustic design and sound insulation renovation of existing buildings, and improve the acoustic environment mass of the building.
