This document specifies basic framework measurement methods for sound immission from sound
sources placed close to the ear. These measurements are carried out with a manikin, equipped
with ear simulators including microphones. The measured values are subsequently converted into
corresponding free-field or diffuse-field levels. The results are given as free-field related or diffusefield
related equivalent continuous A-weighted sound pressure levels. The technique is denoted the
manikin technique.
This document is applicable to exposure to sound from sources close to the ear, for example during
equipment tests or at the workplace to sound from earphones or hearing protectors with audio
communication facilities.
This document is applicable in the frequency range from 20 Hz to 10 kHz. For frequencies above 10 kHz,
ISO 11904-1 can be used.

The present document applies to equipment operating on radio frequencies between 25 MHz and 3 GHz, using
analogue, digital and hybrid (using both analogue and digital modulation) modulation.
The present document applies to the following radio equipment types:
• Professional Wireless Microphone Systems (PWMS);
• in ear monitoring systems;
• consumer radio microphones;
• tour guide systems; and
• Assistive Listening Devices (Aids for the handicapped) comprising personal and public hearing aid systems.
The maximum power recommended for equipment covered by the present document is 250 mW for radio microphones
and 500 mW for public hearing aids in the 169,4 MHz to 169,8125 MHz band (erp below 1 GHz and eirp above
1 GHz).
The present document also covers radio microphones used in the 863 MHz to 865 MHz band, with a maximum power
of 10 mW.
The present document is intended to cover the provisions of Directive 1999/5/EC [i.1] (R&TTE Directive):
Article 3.2, which states that "….. radio equipment shall be so constructed that it effectively uses the spectrum allocated
to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of Article 3 of the R&TTE Directive may apply to equipment within the scope of the present
document.

The present document covers the minimum characteristics considered necessary in order to make the best use of the
available frequency spectrum for wireless microphones and Aids for the hearing impaired.
The present document specifies the minimum performance requirements and the methods of measurement of Assistive
Listening Devices, radio microphones and in-ear monitoring systems. It does not necessarily include all the
characteristics that may be required by a user, nor does it necessarily represent the optimum performance achievable.
The present document applies to equipment operating on radio frequencies between 25 MHz and 3 GHz (as shown in
table 1) using analogue, digital and hybrid (using both analogue and digital) modulation.
The maximum power recommended for equipment covered by the present document is 250 mW for radio microphones
and 10 mW for ALDs.
An exception to this are the Public Hearing Aids defined in the CEPT Report 004 [i.9] and subsequent ECC [i.11] and
EC Decisions [i.10] on the ex ERMES band (169,4 MHz to 169,8125 MHz) where 500 mW is defined.
The present document also covers radio microphones used in the 863 MHz to 865 MHz band, with a maximum power
of 10 mW.
Electromagnetic Compatibility (EMC) requirements are covered by ETSI EN 301 489-9 [i.4].
National regulations on:
1) maximum power output;
2) licensing status;
will apply or those detailed in the latest version of:
• EC Decision 2005/928/EC [i.11];
• ECC/DEC/(05)02 [i.12];
• the EC SRD Decision [i.10]; or
• CEPT/ERC/REC 70-03 [i.8], annex 10 (see http://www.erodocdb.dk/).
Unless otherwise stated in the EC SRD Decision, ECC Decision or National Interfaces, Radio Microphones can be
subject to individual licence.
The types of equipment covered by the present document are as follows:
• in ear monitoring systems;
• consumer radio microphones;
• tour guide systems; and
• Assistive Listening Devices (Aids for the handicapped) comprising personal and public hearing aid systems.

IEC 61158-6-23:2014 defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-23, and define the externally visible behaviour associated with their transfer. This standard specifies the protocol of the IEC fieldbus Application Layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545).
