design and performance requirements, marking requirements and user information relating to the incorporation of
the electrical audio input facility.
The requirements of this standard are intended to take account of the ergonomic interaction between the
wearer, the device and, where possible, the working environment in which the device is likely to be used (see
Annex ZA of this standard and EN 458)
