DIN EN ISO 266:1997-08

Acoustic - Preferred frequencies (ISO 266:1997); German version EN ISO 266:1997

Edition date: 1997-08-01
In Force
Available languages: English, German
Summary: The document specifies a series of preferred frequencies in order to provide a common basis for comparing the results of acoustical measurements. The frequency series is referred to the reference frequency of 1000 Hz, which is also the reference frequency to the definition of the phon (see ISO 31-7). The specification of the preferred frequency series reduces to a minimum the number of frequencie at which acoustical data need to be tabulated. Also measurement equipment may be specifically constructed for these frequencies.

Das Dokument beinhaltet die Festlegung einer Folge von Normfrequenzen, um die Vergleichbarkeit der Ergebnisse akustischer Messungen auf einer gemeinsamen Grundlage zu ermöglichen. Die Frequenzreihe bezieht sich auf die Referenzfrequenz von 1000 Hz, die auch die Referenzfrequenz für die Definition des Phon (siehe ISO 31-7) darstellt. Die Festlegung einer Normfrequenzreihe reduziert die Anzahl der Frequenzen, für welche akustische Daten erhoben werden müssen, auf ein Minimum. Auch dürfen Meßgeräte speziell für diese Frequenzen hergestellt werden.
