ISO10140-2
Part of the ISO 10140 series, ISO 10140-2 focuses on measuring the airborne sound insulation of building components in a laboratory. This standard offers a consistent way to assess how well different building elements, like doors, floors, and walls, can cut down on sound transmission.
Use of ISO10140-2:
Architects, engineers, and acoustic consultants use the Acoustic Performance Assessment to evaluate how well building materials and assemblies insulate against sound.
Product Development and Certification: Using this standard, producers test and certify their goods to make sure they satisfy pertinent sound insulation requirements.
Regulatory Compliance: In order to comply with building codes and regulations concerning sound insulation in residential and commercial constructions, ISO 10140-2 compliance is frequently necessary.
Method of ISO10140-2:
Preparing the Sample:
The test sample, such as a wall, floor, or door, is built with precise measurements that correspond to its intended use.
To ensure a reliable evaluation of the sample’s sound-isolating qualities, it must be installed in a manner that mimics actual circumstances.
Environment for Testing:
A source room, where sound is produced, and a receiving room, where sound transmission is measured, are usually used in the controlled laboratory setting where testing is carried out.
Method of Measurement:
Sound Generation: In the source room, a sound source continuously produces a noise signal, such as pink noise.
Data collection: Both rooms have well-placed microphones. Both the source room and the receiving room measure the sound pressure levels at the same time.
Sound Insulation Calculation: By comparing the sound levels recorded in the two rooms, the sound insulation value (R) is determined.
Analyzing Data:
Based on the results, the building element’s ability to effectively block sound transmission is indicated by its sound insulation rating (R), which is expressed in decibels (dB) across a range of frequencies.
The findings, which offer comprehensive insights into the material’s acoustic qualities, are usually displayed as a graph of sound insulation performance across a range of frequencies.
For building components to effectively reduce sound transmission and improve acoustic comfort and privacy in a variety of settings, including homes, workplaces, and public areas, ISO 10140-2 is essential.
