ISO 23771:2015 provides technical information on the design of textile machinery with reduced noise emissions. Textile machines with a significant noise hazard are defined in ISO 11111 (all parts). ISO 23771:2015 supports the technical designer with the development of low-noise textile machinery. For this purpose, the significant sources of noise of the individual types of textile machines and suitable noise control measures are described.

Overview

EN ISO 23771:2015 - Textile machinery: Guide to the design of textile machinery for reduction of the noise emissions (ISO 23771:2015) provides technical guidance for designing low-noise textile machines. It supports designers and manufacturers in identifying significant noise sources, applying effective noise control measures and verifying results. The standard targets textile machines that may present a significant noise hazard (see ISO 11111); a noise hazard is defined in ISO 23771 as an A-weighted emission sound pressure level at an operating position higher than 70 dB(A) (with probable real-world values ≥ 80 dB(A)).

Key Topics

Noise measurement and detection

Measurement per ISO 9902 (all parts) to detect emission levels and determine if further action is required.

Identification of significant noise sources

Recommended methods: analysis of rotating speeds and dominant frequencies, comparative measurements under varying parameters, sound intensity mapping, and structure-borne noise calculation/simulation.

Noise control strategy and hierarchy

Preferred order of measures:
1. Reduce sound generation at the source
2. Reduce sound propagation (enclosures, barriers, damping)
3. Design for reliable installation, maintenance and spare parts to ensure sustained low-noise operation
4. Use of hearing protection where necessary

Verification of effectiveness

Re-measurement and verification (ISO 9902) and documentation for machine handbooks.

Machine categories covered

Spinning and spinning preparatory machines, non-woven machinery, yarn processing, cordage/rope manufacture, weaving and knitting preparatory machinery, fabric manufacturing, dyeing and finishing machines - sources and specific control measures are described by machine type.

Scope limits

Elements not part of the textile machine itself (e.g., material transport systems, external media supplies) are excluded.

Applications

Machine designers and OEMs developing low-noise textile equipment

Acoustic engineers and consultants performing noise audits and mitigation design

Safety and compliance officers ensuring conformity with machinery safety and noise limits

Procurement and plant managers specifying low-noise equipment for production lines Practical benefits include reduced worker exposure, improved compliance with occupational noise requirements, and better marketability of quieter textile machinery.
