Overview

EN ISO 11688-1:2009 (ISO/TR 11688-1:1995) - “Acoustics - Recommended practice for the design of low-noise machinery and equipment - Part 1: Planning” is a technical report adopted by CEN to help designers incorporate noise control from the earliest project phases. It explains basic acoustical concepts and presents a methodical design process to reduce noise emissions in machinery and equipment. The document supports conformity with EU machinery directives (see informative Annexes ZA and ZB) and cross-references established ISO measurement and declaration methods.

Key topics and requirements

Design process for low-noise machinery: Describes four iterative phases - clarification of task (requirements), conceptual design, detailed design, and prototyping/final testing - with acoustical checkpoints at each stage.

Noise source classification: Differentiates active components (noise generators) from passive components (structural radiators) and distinguishes tonal, periodic and broadband noise.

Design rules and controls: Summarized guidance (Annex A) and noise control requirements (Annex B) for selecting materials, dimensions, and concepts that minimize airborne, structure-borne and fluid-borne noise.

Measurement and verification: Recommends use of established ISO methods for quantifying noise and source strengths; references include ISO 3744, ISO 3746, ISO 4871, ISO 9611, ISO 9614-1/-2, ISO 11200 and ISO 11689.

Documentation and reporting: Annex C lists information to be reported; Annex D provides a bibliography of acoustical literature for further study.

Practical scope: Serves as an aid to non-acoustic engineers and design teams to assess, compare and implement noise reduction measures during product development.

Practical applications

Integrating noise control into early product planning and requirement specification.

Comparing alternative machine concepts by predicted noise performance (design trade-offs).

Guiding prototype testing and acoustical diagnosis to target the most effective noise mitigation measures.

Supporting compliance evidence for noise emission requirements and EU machinery directives.

Informing purchasing/specification decisions where low-noise performance is a competitive or regulatory requirement.
