ASTM E336-16a – Standard Test Method for Measurement of Airborne Sound Attenuation between Rooms in Buildings
5.1 The main part of this standard uses procedures originally developed for laboratory measurements of the transmission loss of partitions. These procedures assume that the rooms in which the measurements are made have a sound field that reasonably approximates a diffuse field. Sound pressure levels in such rooms are reasonably uniform throughout the room and […]
ASTM E336-20 – Standard Test Method For Measurement Of Airborne Sound Attenuation Between Rooms In Buildings
5.1 The main part of this standard uses procedures originally developed for laboratory measurements of the sound transmission loss of partitions. These procedures assume that the rooms in which the measurements are performed have a sound field that reasonably approximates a diffuse field. Sound pressure levels in such rooms are reasonably uniform throughout the room and […]
ASTM E90-09(2016) – Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions and Elements
Significance and Use 5.1 Sound transmission loss as defined in Terminology C634, refers to the response of specimens exposed to a diffuse incident sound field, and this is the test condition approached by this laboratory test method. The test results are therefore most directly relevant to the performance of similar specimens exposed to similar sound […]
ISO 10140-2:2021 – Acoustics — Laboratory measurement of sound insulation of building elements — Part 2: Measurement of airborne sound insulation
1. Scope This document specifies a laboratory method for measuring the airborne sound insulation of building products, such as walls, floors, doors, windows, shutters, façade elements, façades, glazing, small technical elements, for instance transfer air devices, airing panels (ventilation panels), outdoor air intakes, electrical raceways, transit sealing systems and combinations, for example walls or floors […]
ISO 717-1:2020 Acoustics — Rating of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation
Introduction Methods of measurement of airborne sound insulation of building elements and in buildings have been standardized e.g. in ISO 10140-2 and ISO 16283-1. The purpose of this document is to standardize a method whereby the frequency-dependent values of airborne sound insulation can be converted into a single number characterizing the acoustical performance. References to […]
ISO 717-1:2013 – Acoustics — Rating of sound insulation in buildings and of building elements — Part 1: Airborne sound insulation
ISO 717-1:2013: a) defines single-number quantities for airborne sound insulation in buildings and of building elements such as walls, floors, doors, and windows; b) takes into consideration the different sound level spectra of various noise sources such as noise sources inside a building and traffic outside a building; c) gives rules for determining these quantities […]
Tiêu chuẩn Việt Nam TCVN 7192 – 2 : 2002 – Âm học – đánh giá cách âm trong các công trình xây dựng và kết cấu xây dựng – phần 2: cách âm va chạm
Văn bản này nhằm hoàn thiện các dữ liệu trong tiêu chuẩn TCVN 7192–1 (ISO 717–1) và TCVN 7192–2 (ISO 717–2) vì các dữ liệu đó chưa thật chính xác và dẫn đến sự diễn giải khác nhau về các dữ liệu thu được, đặc biệt là khi thực hiện số hóa trong phần mềm […]
ISO 11546-2:1995 – Acoustics — Determination of sound insulation performances of enclosures — Part 2: Measurements in situ (for acceptance and verification purposes)
1. Scope This part of ISO 11546 specifies in situ methods for the determination of the sound insulation performance (insertion loss) of machine enclosures. It applies to a total enclosure only and not to the individual panels from which the enclosure is made. NOTES 1 – Sound insulation for enclosure panels such as wall elements, […]
