Issue date: 2020 11 01

Acoustics - Determination and application of measurement uncertainties in building acoustics - Part 2: Sound absorption (ISO 12999-2:2020)

This document specifies how to calculate: — the uncertainty of sound absorption coefficients and equivalent sound absorption areas measured according to ISO 354; — the uncertainty of the practical and weighted sound absorption coefficients determined according to ISO 11654; — the uncertainty of the object sound absorption coefficient according to ISO 20189; and — the uncertainty of the single number rating determined according to EN 1793-1. Furthermore, the use of uncertainties in reporting measured or weighted sound absorption coefficients is explained.

Frequently Asked Questions about ÖNORM EN ISO 12999-2

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.

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.
