TS EN ISO 80000-8

TS EN ISO 80000-8 is part of the Quantities and units series and focuses on the names, symbols, definitions and units used for quantities in acoustics. Clear and consistent expression of acoustic quantities is important for interpreting measurement results, comparing technical documents and maintaining a common language across engineering and science.

How acoustic quantities are organised

This standard systematises the terminology used for acoustic quantities. In acoustics, key concepts commonly include sound pressure, sound power, sound intensity, frequency and related level quantities; each represents a different physical aspect of sound. Standards of this kind help prevent confusion between symbols and units and improve consistency in technical communication.

What the document provides in practice

According to the scope, the document gives the names, symbols, definitions and units for quantities of acoustics, and where appropriate it also provides conversion factors. In practical terms, this supports clearer measurement reports, engineering calculations, product data sheets and scientific publications by reducing ambiguity when the same quantity is expressed in different ways. In general technical context, accurate definition of acoustic quantities is foundational in areas such as noise assessment, building acoustics, machinery acoustics and sound technology.

• Standardises names and symbol usage.
• Provides definitions and units for acoustic quantities.
• Includes conversion factors where appropriate.
• Supports consistency in technical communication.
