Full title and description

ISO 15667:2000 — Acoustics — Guidelines for noise control by enclosures and cabins. This international standard provides guidance on design, performance and specification of acoustic enclosures and operator cabins intended to reduce airborne noise from machines and equipment.

Abstract

ISO 15667:2000 defines performance and application guidance for two primary types of acoustic enclosures: operator protection cabins (self‑contained or mounted on machines) and self‑supporting enclosures that cover or surround machinery. The standard emphasizes lightweight constructions but is applicable to heavy, massive structures as well; it excludes partial enclosures (more than 10 % open untreated surface) and enclosures that are an integral, fixed part of the machine. It also outlines the acoustic and operational requirements that should be agreed between supplier/manufacturer and user.

• Number of pages: Approximately 50 pages (ISO published edition).

Scope

This standard applies to self‑contained operator cabins and to self‑supporting enclosures that cover or envelop machinery where less than 10 % of the enclosure surface is open and untreated acoustically. It provides guidelines for specifying acoustic performance, ventilation, access arrangements, observation/windows, mounting, and service openings, and for establishing test and verification conditions agreed between supplier and user. Partial enclosures (more than 10 % open) and enclosures that are an integral, permanently fixed part of the machine are outside the scope.

Key topics and requirements

• Definition and classification of enclosure/cabin types (operator cabins, self‑supporting enclosures).
• Acoustic performance criteria and how to specify guaranteed attenuation or internal sound levels.
• Design considerations: sound‑insulating panels, absorption, seams and joints, doors and windows, ventilation and HVAC noise, access and safety.
• Measurement, verification and agreement procedures between supplier and user (conditions for testing and acceptance).
• Recommendations on lightweight versus massive construction and limitations regarding partially open enclosures.

Typical use and users

Used by machine builders, equipment manufacturers, acoustic consultants, occupational health and safety engineers, plant designers and end users specifying noise control measures. Typical applications include enclosures for stationary machinery, mobile‑mounted operator cabins (e.g., on construction or lifting equipment) and retrofit enclosures installed to reduce workplace noise exposure.

Related standards

ISO 15667 is part of the ISO acoustics family and is commonly referenced alongside standards for sound power and absorption measurement and sound insulation, for example ISO 3744/3746 (sound power determination), ISO 354 (absorption in reverberation rooms) and ISO 9614 (sound intensity). National/adopted versions include EN/BS/UNE adoptions of ISO 15667. These adjacent standards provide measurement methods and complementary guidance used when specifying or verifying enclosure performance.

FAQ

Q: What is this standard?

A: ISO 15667:2000 is an international guideline standard giving recommendations and specification elements for noise reduction using enclosures and cabins for machinery and operator protection.

Q: What does it cover?

A: It covers guidance on types of enclosures (self‑supporting and operator cabins), acoustic performance expectations, design features (sealing, panels, doors/windows, ventilation), and how supplier and user should agree testing and acceptance conditions. Partial enclosures and integral machine enclosures are excluded.

Q: Who typically uses it?

A: Machine/equipment manufacturers, acoustic consultants, safety/occupational hygiene teams, plant engineers and procurement/specification authors who need to define or verify enclosure performance.

Q: Is it current or superseded?

A: The 2000 edition has been subject to ISO's periodic systematic reviews and was confirmed as the current edition following review processes (confirmation recorded in 2021). Users should check national bodies or ISO for any later amendments or revisions.

Q: Is it part of a series?

A: It sits within ISO/TC 43 (acoustics) work and is commonly used together with other acoustics measurement and specification standards (for example ISO 3744, ISO 354, ISO 9614) that cover measurement methods and related topics.

Q: What are the key keywords?

A: Acoustics; noise control; enclosures; cabins; sound insulation; operator protection; machine noise; ventilation noise; acoustic performance.
