(Main)Measurement microphones — Part 8: Methods for determining the free-field sensitivity of working standard microphones by comparison
Measurement microphones — Part 8: Methods for determining the free-field sensitivity of working standard microphones by comparison
IEC 61094-8:2012 applicable to working standard microphones meeting the requirements of IEC 61094-4. It describes methods of determining the free-field sensitivity by comparison with a laboratory standard microphone or working standard microphone (where applicable) that has been calibrated according to either; IEC 61094-3; IEC 61094-2; IEC 61094-5; IEC 61094-6; or this part of IEC 61094. Methods performed in an acoustical environment that is a good approximation to an ideal free-field (e.g. a high quality free-field chamber), and methods that use post processing of results to minimise the effect of imperfections in the acoustical environment, to simulate free-field conditions, are both covered by this part of IEC 61094. Comparison methods based on the principles described in IEC 61094-3 are also possible but beyond the scope of this part of IEC 61094.

Microphones de mesure — Partie 8: Méthodes pour la détermination de l'efficacité en champ libre par comparaison des microphones étalons de travail
La CEI 61094-8:2012 est applicable aux microphones étalons de travail satisfaisant aux exigences de la CEI 61094-4. Elle décrit des méthodes pour la détermination de l'efficacité en champ libre par comparaison utilisant un microphone étalon de laboratoire ou un microphone étalon de travail (s'il y a lieu) qui a été étalonné d'après les indications d'un des documents suivants: CEI 61094-3; CEI 61094-2; CEI 61094-5; CEI 61094-6; ou a présente partie de la CEI 61094. Les méthodes employées dans un environnement acoustique constituant une bonne approximation d'un champ libre idéal (par exemple une chambre en champ libre de haute qualité) et les méthodes utilisant un post-traitement des résultats pour réduire au maximum l'effet des imperfections de l'environnement acoustique, afin de simuler les conditions d'un champ libre, sont toutes abordées dans la présente partie de la CEI 61094. Des méthodes de comparaison reposant sur les principes décrits dans la 61094-3 peuvent également être utilisées, mais elles sortent du domaine d'application de la présente partie de la CEI 61094.
Elektroakustika - Merilni mikrofoni - 8. del: Metode za primerjalno umerjanje v odprtem prostoru delovnih mikrofonov
Ta del skupine standardov IEC 61094 se uporablja za delovne mikrofone, ki izpolnjujejo zahteve iz standarda IEC 61094-4. Opisuje metode za ugotavljanje občutljivosti v odprtem prostoru s primerjavo z laboratorijskim standardnim mikrofonom ali delovnim mikrofonom (kjer je to primerno), ki je bil umerjen v skladu s:
– standardom IEC 61094-3,
– standardom IEC 61094-2 ali IEC 61094-5, pri čemer so bili uporabljeni faktorji iz standarda IEC/TS 61094-7,
– standardom IEC 61094-6,
– tem delom standarda IEC 61094.
Ta del standarda IEC 61094 zajema metode, ki se izvajajo v akustičnem okolju, ki je dober približek idealnemu prostemu zvočnemu polju (npr. visokokakovostna gluha komora), in metode, pri katerih se rezultati naknadno prilagodijo, da se čim bolj zmanjša učinek nepravilnosti v akustičnem okolju, s čimer se simulirajo pogoji prostega zvočnega polja. Možne so tudi primerjalne metode, ki temeljijo na načelih iz standarda IEC 61094-3, vendar ne spadajo na področje uporabe tega dela standarda IEC 61094.
