TS EN ISO 80000-8

TS EN ISO 80000-8 is a terminology standard that brings together the names, symbols and definitions of quantities and units used in acoustics. In engineering and measurement work involving sound, vibration and wave propagation, it helps avoid inconsistent naming or symbol use; where appropriate, it also provides conversion factors.

Why acoustics is grouped in a separate part

In acoustics, the main objective is to express quantities such as sound pressure, sound power, frequency and related measures in a common language. This is especially useful in laboratory measurements, noise assessment, loudspeaker and microphone characterization, building acoustics and machinery noise work, where terminology differences can easily cause confusion. As a terminology standard, this document supports consistency in naming and symbol use for acoustic quantities; it is not, by itself, a measurement-method standard.

What the scope offers in practice

• Helps keep acoustic terms and symbols consistent in technical documents, drawings and calculations.
• Clarifies relationships between units and, where needed, the relevant conversion factors.
• Supports the same quantity being used with the same meaning across different countries and organizations.
• Works alongside the other parts of the ISO 80000 system to create a coherent language for quantities and units.

The standard was adopted from EN ISO 80000-8 and is grounded in established acoustic measurement practice. Its main value for users is not in prescribing a specific instrument or test, but in ensuring that acoustic quantities are stated clearly and consistently.
