ISO10848-2
An international standard called ISO 10848-2 describes how to measure the airborne sound insulation of building components in situ, or in the actual setting where they are installed. It focuses specifically on measuring the sound insulation between two rooms that are divided by a wall or floor. When evaluating a structure’s acoustic performance under actual circumstances, this standard is essential.
Use of ISO10848-2:
Assessing a building element’s ability to insulate against airborne sound in practical applications is done by acousticians, engineers, and architects.
Regulatory Compliance: Assists in making sure that structures adhere to pertinent sound insulation standards and acoustic regulations.
Quality assurance: Offers a way to confirm the effectiveness of building techniques and sound-insulating materials.
Method of ISO10848-2:
Test Configuration:
A source room, where sound is produced, and a receiving room, where sound is measured, are two adjacent rooms used in the test.
These two rooms are divided by the building element under test, such as a wall or floor.
Method of Measurement:
Sound Generation: A controlled noise signal is produced in the source room by a sound source, such as a loudspeaker. This could be particular frequency tones or broadband noise (like pink noise).
Data collection: To gauge sound levels, microphones are positioned in both rooms. In order to record the sound pressure levels in the source and receiving rooms, measurements are made concurrently.
Sound Level Analysis: It records the difference in sound levels between the two rooms. This involves taking measurements of the sound level in the source room while it is operational and again in the receiving room.
Analyzing Data:
The difference in sound levels between the source and receiving rooms is used to calculate the sound insulation level, which is typically expressed in decibels, or dB.
The outcomes are examined to ascertain how well the building element insulates against airborne sound at various frequencies.
To ensure that sound insulation measures are successful in delivering comfort and privacy in residential, commercial, and public spaces, ISO 10848-2 is crucial for precisely evaluating the acoustic performance of building elements in real-life settings.
