Summary

The Finnish Ministry of the Environment's glossary entry for the sign that marks a space or service point with an induction loop, linked to an entry for loop coverage maps.

Key findings

  • Defines the international induction loop symbol as the mark that identifies a space or service point equipped with an induction loop; its English synonyms include hearing loop symbol.
  • States that the symbol is defined in the international standard SFS-EN 60118-4, the European adoption of the loop performance standard IEC 60118-4.
  • States that a space with an induction loop should also have a coverage map. The linked entry defines it as a sign that marks the loop's coverage area on the floor plan, so that a hearing device user can choose the best place to listen.
  • Files both entries under signs, in a glossary that covers accessibility from the point of view of built-environment legislation.

Limits

A glossary entry, not a regulation: it does not name the legal source for the coverage map. The Finnish text was translated for this record. IEC 60118-4 itself is paywalled; its public contents page lists an informative Annex C on the information to provide, with a Figure C.1, "Graphical symbol: inductive coupling", which could not be viewed. The entry shows no date; page metadata records creation on 12 May 2022 and a change on 3 April 2024.
