Electroacoustics - Audio-frequency induction loop systems for assisted hearing - Part 2: Methods of calculating and measuring the low-frequency magnetic field emissions from the loop for assessing conformity with guidelines on limits for human exposure

IEC 62489-2:2014 applies to audio-frequency induction-loop systems for assisted hearing. It may also be applied to such systems used for other purposes, as far as it is applicable. The standard is intended for assessment of human exposure to low-frequency magnetic fields produced by the system, by calculation and by in-situ testing. This standard does not deal with other aspects of safety, for which IEC 60065 applies, or with EMC. This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision which includes significant technical changes to reflect several updates to the ICNIRP Guide (Guidelines for limiting exposure to time-varying electric, magnetic, and electromagnetic fields) to which it makes frequent reference. The most significant change is that the underlying metric in the Guide has been changed from tissue current density to induced electric field. Keywords: hearing aid, accessibility, surdity, deafness

Electroacoustique - Systèmes de boucles d'induction audiofréquences pour améliorer l'audition - Partie 2: Méthodes de calcul et de mesure des émissions de champ magnétique basse fréquence à partir de la boucle pour l’évaluation de la conformité aux instructions sur les limites d’exposition humaine

L'IEC 62489-2:2014 s'applique aux systèmes de boucles d'induction audiofréquences pour améliorer l'audition. Elle peut également être appliquée à de tels systèmes utilisés à d'autres fins, si ladite application est possible. La norme est destinée à l'évaluation de l'exposition humaine à des champs magnétiques basse fréquence produits par le système, par le calcul et par l'essai in-situ. La présente norme ne traite pas d'autres aspects de la sécurité, pour laquelle l'IEC 60065 s'applique, ni de la CEM. Cette deuxième édition annule et remplace la première édition parue en 2011. Cette édition constitue une révision technique qui inclut les modifications techniques majeures afin de refleter plusieurs mises à jour du Guide ICNIRP (Guidelines for limiting exposure to time-varying electric, magnetic, and electromagnetic fields) auquel il est fait fréquemment référence. Le changement le plus significatif est que la grandeur de base dans le guide est passée d'une densité de courant dans les tissus à un champ électrique induit. Mots clé: accessibilité, sonotone, surdité

Elektroakustika - Sistemi z avdiofrekvenčno indukcijsko zanko za slušne pripomočke - 2. del: Metode za računanje in merjenje nizkofrekvenčnega sevanja magnetnega polja iz zanke pri ocenjevanju skladnosti s smernicami o omejitvi izpostavljenosti ljudi (IEC 62489-2:2014)

Ta del standarda IEC 62489 se uporablja za sisteme z avdiofrekvenčno indukcijsko zanko za slušne pripomočke. Uporablja se lahko tudi za takšne sisteme, ki se uporabljajo za druge namene, v kolikor je to primerno. Standard je namenjen za ocenjevanje izpostavljenosti ljudi nizkofrekvenčnim magnetnim poljem, ki jih proizvaja sistem, in sicer z izračunom ali preskusom na kraju samem. Ta standard ne obravnava drugih vidikov varnosti, za katere velja standard IEC 60065, ali elektromagnetne združljivosti (EMC).
