ÖNORM EN ISO 26101-2

Issue date: 2024 12 15

Acoustics - Test methods for the qualification of the acoustic environment - Part 2: Determination of the environmental correction (ISO 26101-2:2024)

This document specifies methods for qualifying an environment that approximates to an acoustic free field near one or more reflecting planes. The goal of the qualification is to determine the environmental correction K2, which is used to correct for reflected sound when determining the sound power level or sound energy level of a noise source from sound pressure levels measured on a surface enveloping the noise source (machinery or equipment) in such an environment. In practice, the K2 value determined will be a function of both the reflected sound from the test environment and the shape and size of the measurement surface used for the K2 determination. For the purposes of this document and the documents that refer to it, the differences between K2 values determined with different measurement surfaces are assumed to be included in the stated measurement uncertainty for the test method.

Frequently Asked Questions about ÖNORM EN ISO 26101-2

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

How can I get involved in the further development of this standard?

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
