Overview

EN ISO 11203:2009 (Acoustics) specifies methods to determine emission sound pressure levels at a work station and at other specified positions by calculation from the sound power level of machinery and equipment. Adopted by CEN from ISO 11203:1995, it is intended primarily to allow comparison between different units of a family of machines under defined environmental, mounting and operating conditions. The standard is part of the ISO 11200 series on machinery noise.

Key topics and requirements

Two calculation methods for deriving emission sound pressure levels from measured sound power levels (see clauses referenced for specific fields of application).

Scope of application: suitable for stationary or moving machines, indoor or outdoor use, especially mass‑produced machines (commonly machines ≤ 1 m largest dimension; larger machines covered in specific cases). Not intended for highly directional outdoor sources or positions inside cabs/cabins.

Test environment: requires the same acoustical conditions used for sound power determination (referenced ISO 3740 / ISO 9614 family test environments).

Descriptors and weighting: emission sound pressure levels shall use the same frequency and time weighting (or frequency bands) as the sound power measurement. The standard defines emission sound pressure level Lp and time‑averaged level Lp,eq,T (LpAeqT for A‑weighted measurements) consistent with IEC/ISO measurement practice.

Purpose: enables comparison, declaration and verification of emission sound pressure levels (linked to ISO 4871 requirements for noise declaration).

Regulatory relevance: informative annexes relate compliance to EU Directives (e.g., 98/37/EC and 2006/42/EC), providing a presumption of conformity when cited in the Official Journal - note other directives or requirements may also apply.

Applications and users

Practical uses:

Comparing noise performance across production runs or different models.
Creating noise declarations for product documentation and labels.
Input for workplace noise assessments and acoustic planning when machines operate alone under standardized conditions.

Typical users:

Acoustic engineers and test laboratories performing machinery noise testing.
Product compliance teams and manufacturers of industrial machinery.
Health & safety professionals, regulatory authorities and procurement specialists evaluating equipment noise.
