Full title and description

Acoustics — Noise emitted by machinery and equipment — Guidelines for the use of basic standards for the determination of emission sound pressure levels at a work station and at other specified positions. This document is the frame standard for the ISO 11200 series and provides guidance for selecting and applying the basic measurement standards (ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205) when determining emission sound pressure levels at work stations and other specified positions for machinery and equipment.

Abstract

ISO 11200:2014 is a frame (guidance) standard introducing and tying together the basic group of standards used to determine emission sound pressure levels at work stations and other specified positions. It explains the physical meaning of the emission sound pressure quantity, compares measurement methods offered by the group, and helps users choose the most appropriate method(s) in practical situations. The standard applies to airborne sound only and is intended for general noise testing and for use when preparing standardized noise test codes.

Scope

Provides guidance for the selection and use of the basic standards in the ISO 11200 family for determination of emission sound pressure levels at a work station and at other specified positions. The standard is limited to airborne sound and is intended to facilitate the writing of noise test codes, to explain the physical basis of the emission sound pressure quantity compared to other acoustic quantities, and to compare the different measurement methods available in the ISO 11201–11205 group so users can choose the appropriate method for typical practical situations.

Key topics and requirements

• Definition and physical interpretation of emission sound pressure levels used for characterizing machine noise at work stations and specified positions.
• Guidance for selecting the appropriate basic standard from the ISO 11201–11205 group depending on machine type, test conditions and positions.
• Comparison of measurement methods (e.g., position and averaging rules, microphone placement, handling of background noise) to aid choice of method.
• Considerations for writing noise test codes: recommended mounting and operating conditions, and specification of work station(s) and other specified positions.
• Reference to an amendment (ISO 11200:2014/Amd 1:2018) that provides subsequent corrections/clarifications.

Typical use and users

Used by acoustics laboratories, test houses, manufacturers of machinery and equipment, standards developers and regulatory bodies when specifying or performing noise emission measurements at work stations and other specified positions. It is especially useful for writers of noise test codes who must select and apply the appropriate ISO 1120x basic standard(s) and define test setups, operating conditions and measurement positions.

Related standards

Main related documents are the ISO 1120x series that ISO 11200 frames and references: ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 (each covering specific measurement methods and setups for different machine families or measurement situations). Earlier versions (ISO 11200:1995) were withdrawn and replaced by the 2014 edition; an amendment was published in 2018. Users may also consult other acoustics standards for complementary measurement and reporting practices as relevant to sound power or environmental noise.
