Full title and description
ISO 22259:2019 — Conference systems — Equipment — Requirements. This International Standard specifies performance and interoperability requirements for conference system equipment and their auxiliary devices (for example microphones, headphones and sound reinforcement equipment) and describes the environment in which such systems are used. It applies to both wired and wireless conference systems and provides a common technical basis for related ISO standards.
Abstract
ISO 22259:2019 defines the essential requirements and characteristics for typical conference systems to ensure consistent performance and interoperability under normal operating conditions. The standard covers system components, auxiliary devices, and venue/environment considerations (see Annex A). It facilitates comparison of products, quality assessment and supports downstream standards such as ISO 20108 and ISO 20109.

Scope
This document specifies requirements for typical conference systems, the parts they are composed of, and the auxiliary devices necessary for their use (such as microphones, headphones and sound reinforcement equipment). It applies to both wired and wireless systems and describes relevant environment and venue characteristics in Annex A. The standard is intended to enable determination of system quality, comparison between different systems and assessment of correct use.
Key topics and requirements
- Definitions and classification of conference system components and subsystems (base stations, delegate units, chairman units, expansion devices).
- Performance requirements for audio equipment (microphones, amplifiers, loudspeakers, headphones) to ensure intelligibility and low distortion in typical meeting environments.
- Interoperability and interface requirements to support component combinations from different manufacturers.
- Applicability to both wired and wireless conference system implementations.
- Environmental and venue considerations (acoustic environment, room layouts and recommended placement) described in Annex A.
- Requirements for auxiliary and assistive devices to support accessibility (e.g., hearing assistance systems and headphone interfaces).
- Reference to testable characteristics and normative references for electroacoustic measurements and accessory equipment.
Typical use and users
Used by manufacturers and product developers to design and test conference equipment; by system integrators and AV consultants for specifying and installing systems; by facility managers and event organizers to select and compare conference solutions; and by test laboratories and conformity assessment bodies for verifying performance against standardised criteria. Accessibility and assistive-technology specialists also consult the standard when ensuring compatibility with hearing-assistance systems.
Related standards
ISO 20108 (interpretation and translation systems) and ISO 20109 (simultaneous interpreting equipment) are supported by the technical backbone provided in ISO 22259. Normative and related references include IEC electroacoustics and sound system standards such as IEC 60118-4 (induction-loop systems), IEC 60268-4 (microphones) and IEC 60268-7 (headphones and earphones). Regional adoptions and harmonizations (for example EN/ONORM national editions) may exist based on ISO 22259:2019.
