简介：ISO 3746:2010 specifies methods for determining the sound power level or sound energy level of a noise source from sound pressure levels measured on a surface enveloping a noise source (machinery or equipment) in a test environment for which requirements are given. The sound power level (or, in the case of noise bursts or transient noise emission, the sound energy level) produced by the noise source with frequency A-weighting applied is calculated using those measurements.The methods specified in ISO 3746:2010 are suitable for all types of noise (steady, non-steady, fluctuating, isolated bursts of sound energy, etc.) defined in ISO 12001.ISO 3746:2010 is ap

The sound power level (or, in the case of noise bursts or transient noise emission, the sound energy level) produced by the noise source with frequency A-weighting applied is calculated using those measurements.NOTE Differently shaped measurement surfaces can yield differing estimates of the sound power level of a given noise source and an appropriately drafted test code (see ISO 12001) gives detailed information on the selection of the surface.

EN ISO 3746-2010 声学.声压法测定噪声源声功率级使用标准声源简易法,通过密封测量表面参考反射面的方式测得
简介：Diese Internationale Norm legt Verfahren für die Bestimmung der Schallleistungs- oder Schallenergiepegel einer Ger?uschquelle aus Schalldruckpegeln fest, die auf einer Fl?che gemessen werden, die die Ger?uschquelle (eine Maschine oder ein Ger?t) umschlie?t (Hüllfl?che), wobei sich die Ger?uschquelle in einer Messumgebung befindet, für die Anforderungen angegeben werden. Der von der Ger?uschquelle abgestrahlte A-bewertete Schallleistungspegel (oder Schallenergiepegel bei Impulsen oder anderen Ger?uschen kurzer Dauer) wird aus den gemessenen Schalldruckpegeln berechnet. ANMERKUNG Unterschiedliche Messfl?chenformen k?nnen zu unterschiedlichen Sch?tzwerten des Schallleistungspegels der betrachteten Ger?uschquelle führen. Daher sind geeignet formulierten Ger?uschmessnorm (siehe ISO 12001) genaue Angaben zur Auswahl der Messfl?che enthalten. Die in dieser Internationalen Norm festgelegten Verfahren sind für alle in ISO 12001 definierten Arten von Ger?uschen geeignet (gleichf?rmige, ungleichf?rmige, schwankende, Einzel-Schallimpulse usw.). Diese Internationale Norm gilt für Ger?uschquellen aller Art und Gr??e (z. B. eine station?re oder sich langsam fortbewegende Anlage, technische Einrichtung, Maschine, Komponente oder Baugruppe), solange die Messbedingungen erfüllt werden k?nnen. ANMERKUNG Die Messbedingungen nach dieser Internationalen Norm k?nnen in der Praxis bei sehr hohen oder sehr langen Ger?uschquellen wie Schornsteinen, Kan?len, F?rderb?ndern und Industrieanlagen mit vielen Ger?uschquellen zu Schwierigkeiten führen. In solchen F?llen k?nnen in einer Ger?uschmessnorm für diese speziellen Quellen alternative Verfahren angegeben sein. Als Umgebung zur Durchführung von Messungen nach dieser Internationalen Norm eignet sich ein Ort in einem geschlossenen Raum oder im Freien, der eine oder mehrere Schall reflektierende Ebenen aufweist, auf der oder in deren N?he die zu untersuchende Ger?uschquelle angeordnet wird. Es werden Angaben zur Unsicherheit der nach dieser Internationalen Norm ermittelten A-bewerteten Schallleistungs- und Schallenergiepegel gemacht. Die Unsicherheit entspricht der Genauigkeitsklasse 3 nach ISO 12001:1996.

简介：1.1 GeneralThis International Standard specifies a method formeasuring the sound pressure levels on a measure-ment surface enveloping the source in order to cal-culate the sound power level produced by the noisesource. It gives requirements for the test environmentand instrumentation as well as techniques for obtain-ing the surface sound pressure level from which thesound power level of the source is calculated, leadingto results which have a grade 3 accuracy.It is important that specific noise test codes for vari-ous types of equipment be established and used inaccordance with this International Standard. For eachtype of equipment, such noise test codes will givedetailed requirements on mounting, loading and op-erating conditions for the equipment under test aswell as a selection of the measurement surface andthe microphone array as specified in this InternationalStandard.NOTE 1 The noise test code for a particular type ofequipment should give detailed information on the particularsurface that is selected, as the use of differently shapedmeasurement surfaces may yield differing estimates of thesound power level of a source.1.2 Types of noise and noise sourcesThe method specified in this International Standard issuitable for measurements of all types of noise.NOTE 2 A classification of different types of noise(steady, non-steady, quasi-steady, impulsive, etc.) is givenin ISO 12001.This International Standard is applicable to noisesources of any type and size (e.g. device, machine,component, sub-assembly).NOTE 3 Measurements according to this InternationalStandard may be impracticable for very tall or very longsources such as chimneys, ducts, conveyors and multi-source industrial plants.1.3 Test environmentThe test environment that is applicable for measure-ments made in accordance with this InternationalStandard may be located indoors or outdoors, withone or more reflecting planes present, meetingspecified requirements.
