Electroacoustics - Simulators of human head and ear - Part 3: Acoustic coupler for the calibration of supra-aural earphones used in audiometry

IEC 60318-3:2014 specifies an acoustic coupler for the measurement of supra-aural audiometric earphones in the frequency range from 125 Hz to 8 000 Hz. The sound pressure developed by an earphone is not, in general, the same in the coupler as in a person's ear. However, the acoustic coupler can be used as an objective and reproducible means of measuring the output of supra-aural earphones. It can be used for specifying reference equivalent threshold sound pressure levels for the calibration of audiometers. This second edition cancels and replaces the first edition published in 1998 and constitutes a technical revision which includes the following significant technical changes with respect to the previous edition: - adjustment of terms and wording to the other parts of IEC 60318; - introduction of maximum permitted uncertainties; - and revised requirements for static pressure equalization. Keywords: electroacoustics, deafness, hearing aids

Électroacoustique - Simulateurs de tête et d'oreille humaines - Partie 3: Coupleur acoustique pour l’étalonnage des écouteurs supra-auraux utilisés en audiométrie

L'IEC 60318-3:2014 spécifie un coupleur acoustique destiné à la mesure des écouteurs audiométriques supra-auraux, dans la plage de fréquences comprise entre 125 Hz et 8 000 Hz. La pression acoustique produite par un écouteur n'est pas, en général, la même dans ce coupleur et dans une oreille humaine. Toutefois, le coupleur acoustique peut être utilisé en tant que moyen objectif et reproductible de mesurer la valeur de sortie des casques supra-auraux. Il peut être utilisé pour préciser les niveaux de référence équivalents au seuil de pression acoustique pour l'étalonnage des audiomètres. Cette deuxième édition annule et remplace la première édition parue en 1998. Cette édition constitue une révision technique qui inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - réajustement des termes et formulation par rapport aux autres parties de l'IEC 60318; - introduction des incertitudes maximales permises; - et exigences révisées pour l'égalisation de la pression statique. Mots clé: électroacourtique, surdité, sonotone

Elektroakustika - Simulatorji človeške glave in ušes - 3. del: Akustični spojnik za kalibriranje naušnih slušalk, ki se uporabljajo v avdiometriji

Ta del standarda IEC 60318 določa akustični spojnik za merjenje naušnih avdiometričnih slušalk v frekvenčnem območju od 125 Hz do 8 000 Hz. Zvočni tlak, ki ga proizvede slušalka, se v splošnem v spojniku in v ušesu osebe razlikuje. Vendar se lahko akustični spojnik uporablja kot objektiven in ponovljiv način za merjenje izhodnih signalov naušnih slušalk. Uporablja se lahko za določanje referenčnih enakovrednih mejnih ravni zvočnega tlaka (RESPL) za umerjanje avdiometrov.
