Sound system equipment - Part 21: Acoustical (output-based) measurements

IEC 60268-21:2018 specifies an acoustical measurement method that applies to electro-acoustical transducers and passive and active sound systems, such as loudspeakers, TV-sets, multi-media devices, personal portable audio devices, automotive sound systems and professional equipment. The device under test (DUT) can be comprised of electrical components performing analogue and digital signal processing prior to the passive actuators performing a transduction of the electrical input into an acoustical output signal. This document describes only physical measurements that assess the transfer behaviour of the DUT between an arbitrary analogue or digital input signal and the acoustical output at any point in the near and far field of the system. This includes operating the DUT in both the small and large signal domains. The influence of the acoustical boundary conditions of the target application (e.g. car interior) can also be considered in the physical evaluation of the sound system. This document does not assess the perception and cognitive evaluation of the reproduced sound and the impact of perceived sound quality.

Elektroakustische Geräte - Teil 21: Akustische (ausgabebasierte) Messungen

Équipements pour systèmes électroacoustiques - Partie 21 : Mesures acoustiques (en sortie)

IEC 60268-21:2018 spécifie une méthode de mesure acoustique qui s’applique aux transducteurs électroacoustiques ainsi qu’aux systèmes électroacoustiques passifs et actifs tels que les haut-parleurs, les téléviseurs, les appareils multimédias, les appareils audio personnels portables, les systèmes électroacoustiques pour automobile et les équipements professionnels. L'appareil soumis à essai (DUT) peut être constitué de composants électriques qui effectuent un traitement analogique et numérique des signaux avant la transduction de l’entrée électrique en un signal de sortie acoustique par les excitateurs passifs. Le présent document décrit uniquement les mesures physiques qui évaluent le comportement de transfert du DUT entre un signal d’entrée analogique ou numérique arbitraire et la sortie acoustique en un point quelconque dans le champ proche et lointain du système. Cela inclut le fonctionnement du DUT dans les domaines à la fois des signaux faibles et des signaux forts. L’influence des conditions de limite acoustique de l’application visée (par exemple habitacle de véhicule) peut également être prise en considération dans l’évaluation physique du système électroacoustique. Le présent document n’évalue pas la perception et l’évaluation cognitive du son reproduit ni l’impact de la qualité perçue du son.

Elektroakustične naprave - 21. del: Akustične (izhodne) meritve (IEC 60268-21:2018)

Ta del standarda IEC 60268 določa metodo akustične meritve, ki se uporablja za elektroakustične
pretvornike ter pasivne in aktivne zvočne sisteme, kot so zvočniki, televizorji, večpredstavnostne naprave, osebne prenosne zvočne naprave, avtomobilski zvočni sistemi in profesionalna oprema. Napravo, ki se preskuša (DUT), lahko sestavljajo električne komponente, ki obdelujejo analogni in digitalni signal pred pasivnimi aktuatorji, ki pretvarjajo električni vhodni signal v akustični izhodni signal. Ta dokument opisuje samo fizične meritve za ocenjevanje prenosnega delovanja naprave, ki se preskuša, med poljubnim analognim ali digitalnim vhodnim signalom ter akustičnim izhodnim signalom na kateri koli točki bližnjega in daljnega polja sistema. To vključuje delovanje naprave, ki se preskuša, tako v domenah majhnega kot velikega signala. Pri fizični oceni zvočnega sistema je mogoče upoštevati tudi vpliv akustičnih mejnih pogojev ciljne uporabe (npr. notranjost avtomobila). Ta dokument se ne uporablja za ocenjevanje zaznavanja ter kognitivno vrednotenje
reproduciranega zvoka in vpliva zaznane kakovosti zvoka.
OPOMBA: Nekatere merilne metode, opredeljene v tem dokumentu, je mogoče uporabiti za slušalke, telefone, ušesne slušalke in druge komplete v skladu z določbo [1]1. Ta dokument se ne uporablja za mikrofone in druge senzorje.
Ta dokument ne zahteva dostopa do spremenljivk stanja (napetost, tok) na električnih terminalih pretvornika. Občutljivost, električna vhodna moč in druge značilnosti na podlagi električne impedance bodo opisane v ločenem prihodnjem dokumentu standarda IEC 60268-22, namenjenem električnim in mehanskim meritvam.
