Acoustics - Determination of airborne sound power levels emitted by machinery using vibration measurement - Part 1: Survey method using a fixed radiation factor (ISO/TS 7849-1:2009)

Edition date: 2022-02-16
In Force
Summary: ISO/TS 7849-1:2009 gives basic requirements for reproducible methods for the determination of an upper limit for the A-weighted sound power level of the noise emitted by machinery or equipment by using surface vibration measurements. The method is only applicable to noise which is emitted by vibrating surfaces of solid structures and not to noise generated aerodynamically. This vibration measurement method is especially applicable in cases where accurate direct airborne noise measurements, e.g. as specified in ISO 3746, ISO 3747, and ISO 9614 (all parts), are not possible because of high background noise or other parasitic environmental interferences; or if a distinction is required between the total radiated sound power and its structure vibration generated component. The methods described in ISO/TS 7849-1:2009 apply mainly to processes that are stationary with respect to time.

Dieser Teil von ISO/TS 7849 enthält grundlegende Anforderungen an reproduzierbare Verfahren zur Bestimmung eines oberen Grenzwerts für den A bewerteten Schallleistungspegel der von Maschinen oder Geräten abgestrahlten Geräusche durch Messung von Oberflächenschwingungen. Das Verfahren ist nur auf Geräusche anwendbar, die von schwingenden Oberflächen fester Körper abgestrahlt werden, nicht aber auf aerodynamisch erzeugte Geräusche. Dieses Schwingungsmessverfahren ist insbesondere dann anwendbar, wenn genaue direkte Luftschallmessungen, wie in ISO 3746 [7], ISO 3747 [8] und ISO 9614 (alle Teile) [12] festgelegt, aufgrund starker Fremdgeräusche oder anderer störender Umwelteinflüsse nicht möglich sind oder wenn eine Unterscheidung zwischen der gesamten abgestrahlten Schallleistung und ihrer durch Körperschall erzeugten Komponente erforderlich ist. ANMERKUNG 1 Eine der Anwendungen dieses Teils von ISO/TS 7849 ist die Unterscheidung zwischen der Abstrahlung von Luftschallleistung, die durch Körperschall erzeugt wird, und den aerodynamischen Schallleistungskomponenten. Eine solche Unterscheidung ist mit ISO 3746 [7] und ISO 9614 (alle Teile) [12] nicht möglich. ANMERKUNG 2 Probleme können auftreten, wenn das Geräusch von kleinen Teilen der Maschinenoberflächen (Schleifkontakte, z. B. Schleifringbürste oder der Kommutator und die Bürste in elektrischen Maschinen) erzeugt wird. Die in diesem Teil von ISO/TS 7849 beschriebenen Verfahren gelten hauptsächlich für Prozesse, die zeitlich stationär sind.
