scope:

The main purpose of the present document is to provide guidance for use of terminal equipment using a handset or headset to equipment providers, e.g. operators of contact centres and their suppliers, who seek to ensure that users are not exposed to acoustic pressure levels in excess of the limits set out in Directive 2003/10/EC [i.3].

The present document gives guidance on procedures for measuring acoustic exposure from handset and headset terminal equipment and guidance on the maximum acoustic levels required to protect users' hearing.

The "startle effects" caused by sudden acoustic signals are outside the scope of the present document.

The present document does not deal with loud speaking telephones.
