Acoustics - Determination of sound immission from sound sources placed close to the ear - Part 2: Technique using a manikin (ISO 11904-2:2004)

ISO 11904-2:2004 specifies basic framework measurement methods for sound immission from sound sources placed close to the ear. These measurements are carried out with a manikin, equipped with ear simulators including microphones. The measured values are subsequently converted into corresponding free-field or diffuse-field levels. The results are given as free-field related or diffuse-field related equivalent continuous A-weighted sound pressure levels. The technique is denoted the manikin technique.
ISO 11904-2:2004 is applicable to exposure to sound from sources close to the ear, for example during equipment tests or at the workplace to sound from earphones or hearing protectors with audiocommunication facilities.
ISO 11904-2:2004 is applicable in the frequency range from 20 Hz to 10 kHz. For frequencies above 10 kHz, ISO 11904-1 can be used.

Akustik - Bestimmung der Schallimmission von ohrnahen Schallquellen - Teil 2: Verfahren unter Verwendung eines Kopf- und Rumpfsimulator (ISO 11904-2:2004)

Dieser Teil von ISO 11904 legt Rahmenmessverfahren für die Messung von Schallimmissionen durch ohrnahe Schallquellen fest. Diese Messungen werden unter Verwendung einer Messpuppe durchgeführt, die mit Ohrsimulatoren und Mikrofonen nach ITU-T P.58 ausgestattet ist. Die Messwerte werden im Anschluss in entsprechende Freifeld- oder Diffusfeldpegel umgerechnet. Die Ergebnisse werden als freifeld- oder diffusfeldbezogene A-bewertete äquivalente Dauerschalldruckpegel angegeben werden. Das Verfahren wird als Messpuppen- oder Manikin-Verfahren bezeichnet.
Dieser Teil von ISO 11904 ist anwendbar auf die Exposition durch ohrnahe Schallquellen wie etwa Ohrhörer oder Gehörschützer mit Sprachübertragungssystemen, beispielsweise bei Geräteprüfungen oder am Arbeitsplatz.
Dieser Teil von ISO 11904 ist anwendbar für den Frequenzbereich von 20 Hz bis 10 kHz. Für Frequenzen oberhalb von 10 kHz kann ISO 11904-1 verwendet werden.
