  Description:

Wireless Microphones; Audio PMSE up to 3 GHz; Part 4: Assistive Listening Devices including personal sound amplifiers and inductive systems up to 3 GHz; Harmonised Standard covering the essential requirements of article 3.2 of Directive 2014/53/EU

  Purpose

The present document specifies technical characteristics and methods of measurements for Assistive Listening Devices (ALDs) comprising personal hearing aid systems including inductive systems, personal sound amplifiers, and associated accessories for ALDs, e.g. remote controls and audio streaming devices. The present document applies to equipment operating on radio frequencies up to 3 GHz (as shown in table 1) using analogue, digital and hybrid (using both analogue and digital) modulation. The present document covers the essential requirements of article 3.2 of Directive 2014/53/EU [i.14] under the conditions identified in annex A. NOTE 1: The frequency bands for this equipment may differ from country to country as specified in their national regulations. Table 1: Radiocommunications service frequency bands Radiocommunications service frequency bands Transmit up to 3 000 MHz Receive up to 3 000 MHz NOTE 2: Power limits for different frequency bands can be found in ECC/DEC/(05)02 [i.11]; the EC SRD Decisions [i.9] and [i.16]; EC Decision 2014/641/EU [i.13]; or CEPT/ERC/REC 70-03 [i.7], annex 10 (or European or national regulations).
