Acoustics - Noise emitted by machinery and equipment - Determination of emission sound pressure levels at a work station and at other specified positions in an essentially free field over a reflecting plane with negligible environmental corrections (ISO 11201:2010)
ISO 11201:2010 specifies a method for determining the emission sound pressure levels of machinery or equipment, at a work station and at other specified positions nearby, in an essentially free field over a reflecting plane. A work station is occupied by an operator and may be located in open space, in the room where the source under test operates, in a cab fixed to the source under test, or in an enclosure remote from the source under test. One or more specified positions may be located in the vicinity of a work station, or in the vicinity of an attended or unattended machine. Such positions are sometimes referred to as bystander positions.
Emission sound pressure levels are determined as A-weighted levels. Additionally, levels in frequency bands and C-weighted peak emission sound pressure levels can be determined in accordance with ISO 11201:2010, if required.
With the method specified in ISO 11201:2010, results of accuracy grade 1 (precision grade) or accuracy grade 2 (engineering grade) are obtained. Corrections are applied for background noise, but not for the acoustic environment. Instructions are given for the mounting and operation of the source under test and for the choice of microphone positions for the work station and for other specified positions. One purpose of the measurements is to permit comparison of the performance of different units of a given family of machines, under defined environmental conditions and standardized mounting and operating conditions.
The method specified in ISO 11201:2010 is suitable for all types of noise (steady, non-steady, fluctuating, isolated bursts of sound energy, etc.) defined in ISO 12001.
The method specified in ISO 11201:2010 is applicable to all types and sizes of noise sources.
The type of test environment influences the accuracy of the determination of emission sound pressure levels. For the application of ISO 11201:2010 an essentially free field over a reflecting plane (indoors or outdoors) is required.
ISO 11201:2010 is applicable to work stations and other specified positions where emission sound pressure levels are to be measured.
Appropriate positions where measurements may be made include the following: a) work station located in the vicinity of the source under test; this is the case for many industrial machines and domestic appliances; b) work station within a cab which is an integral part of the source under test; this is the case for many industrial trucks and earth-moving machines; c) work station within a partial or total enclosure (or behind a screen) supplied by the manufacturer as an integral part of the source under test; d) work station partially or totally enclosed by the source under test; this situation may be encountered with some large industrial machines; e) bystander positions occupied by individuals not responsible for the operation of the source under test, but who may be in its immediate vicinity, either occasionally or continuously; f) other specified positions, not necessarily work stations or bystander positions.
The work station may also lie on a specified path along which an operator moves.
Akustik - Geräuschabstrahlung von Maschinen und Geräten - Bestimmung von Emissions-Schalldruckpegeln am Arbeitsplatz und an anderen festgelegten Orten in einem im Wesentlichen freien Schallfeld über einer reflektierenden Ebene mit vernachlässigbaren Umgebungskorrekturen (ISO 11201:2010)
Diese Internationale Norm legt ein Verfahren zur Bestimmung der Emissions-Schalldruckpegel von
Maschinen oder Geräten am Arbeitsplatz und an anderen, sich in der Nähe befindenden, festgelegten Orten
in einem im Wesentlichen freien Schallfeld über einer reflektierenden Ebene fest. Ein Arbeitsplatz wird von
einer Bedienungsperson eingenommen; er kann sich im Freien, in einem Raum, in dem die untersuchte
Quelle betrieben wird, in einer Kabine, die fest mit der untersuchten Quelle verbunden ist, oder in einem von
der untersuchten Quelle entfernt liegenden Bedienerstand befinden. Einer oder mehrere der festgelegten Orte
können in der Umgebung eines Arbeitsplatzes oder im Umfeld einer bedienten oder unbeaufsichtigt
betriebenen Maschine liegen. Derartige Orte werden gelegentlich als „Nachbararbeitsplätze“ bezeichnet.
Emissions-Schalldruckpegel werden als A-bewertete Pegel bestimmt. Falls erforderlich, können zusätzlich
Pegel in Frequenzbändern und C-bewertete Emissions-Spitzenschalldruckpegel nach dieser Internationalen
Norm ermittelt werden.
ANMERKUNG 1 Der Inhalt der Normreihe ISO 11200 [15] bis ISO 11205 [19] ist in ISO 11200 [15] zusammengefasst.
Mit dem in dieser Internationalen Norm festgelegten Verfahren werden Ergebnisse der Genauigkeitsklasse 1
oder der Genauigkeitsklasse 2 erzielt. Korrekturen werden bezüglich des Fremdgeräuschs vorgenommen,
nicht aber bezüglich der akustischen Umgebung. Es werden Anweisungen für die Aufstellung und den Betrieb
der untersuchten Quelle und für die Wahl der Mikrofonpositionen am Arbeitsplatz und den anderen festgelegten
Orten gegeben. Ein Zweck der Messungen besteht darin, einen Vergleich der Daten unterschiedlicher
Exemplare aus einer bestimmten Maschinengruppe unter festgelegten Umgebungsbedingungen und
genormten Aufstellungs- und Betriebsbedingungen zu ermöglichen.
ANMERKUNG 2 Die erhaltenen Daten können auch für die Angabe und Nachprüfung von Emissions-Schalldruckpegeln
nach ISO 4871 [8] verwendet werden.
Acoustique - Bruit émis par les machines et équipements - Détermination des niveaux de pression acoustique d'émission au poste de travail et en d'autres positions spécifiées dans des conditions approchant celles du champ libre sur plan réfléchissant avec des corrections d'environnement négligeables (ISO 11201:2010)
L'ISO 11201:2010 spécifie une méthode de détermination des niveaux de pression acoustique d'émission des machines ou de l'équipement au poste de travail et en d'autres positions spécifiées proches, dans des conditions approchant celles du champ libre sur plan réfléchissant. Le poste de travail occupé par un opérateur peut être situé dans un espace ouvert, dans la salle où la source soumise à essai fonctionne, dans une cabine fixée à la source soumise à essai ou dans une enceinte située à distance de la source soumise à essai. Une ou plusieurs positions spécifiées peuvent se situer au voisinage du poste de travail ou d'une machine avec ou sans opérateur. Ces positions sont parfois appelées «positions d'assistant».
Les niveaux de pression acoustique d'émission sont déterminés en tant que niveaux pondérés A. En outre, les niveaux par bandes de fréquences et les niveaux de pression acoustique d'émission de crête pondérés C peuvent être déterminés selon l'ISO 11201:2010, si nécessaire.
La méthode spécifiée dans l'ISO 11201:2010 permet d'obtenir des résultats de classe de précision 1 (laboratoire) ou de classe de précision 2 (expertise). Des corrections sont appliquées pour le bruit de fond mais pas pour l'environnement acoustique. Des instructions sont fournies pour le montage et le fonctionnement de la source soumise à essai ainsi que pour le choix des positions du microphone pour le poste de travail et pour d'autres positions spécifiées. Un des objets des mesurages est de permettre la comparaison des performances de différentes unités d'une famille donnée de machines, dans des conditions d'environnement définies et dans des conditions de montage et de fonctionnement normalisées.
La méthode spécifiée dans l'ISO 11201:2010 convient à tous les types de bruits (continus, discontinus, fluctuants, pics d'énergie acoustique isolés, etc.) définis dans l'ISO 12001.
La méthode spécifiée dans l'ISO 11201:2010 s'applique à tous les types et toutes les tailles de sources de bruit.
Le type d'environnement d'essai affecte la précision de la détermination des niveaux de pression acoustique d'émission. Pour l'application de l'ISO 11201:2010, les conditions approchant celles du champ libre sur plan réfléchissant (en salle ou en plein air) sont nécessaires.
L'ISO 11201:2010 s'applique aux postes de travail et aux autres positions spécifiées auxquels les niveaux de pression acoustique d'émission doivent être mesurés.
Les positions appropriées où les mesurages peuvent être effectués incluent les positions suivantes: a) poste de travail situé au voisinage de la source soumise à essai, ce qui est le cas de nombreuses machines industrielles et de nombreux appareils domestiques; b) poste de travail à l'intérieur d'une cabine faisant partie intégrante de la machine soumise à essai; ce qui est le cas de nombreux véhicules industriels et engins de terrassement; c) poste de travail à l'intérieur d'une enceinte partielle ou totale (ou derrière un écran), fournie par le fabricant en tant que partie intégrante de la machine ou de l'équipement; d) poste de travail partiellement ou complètement entouré par la source soumise à essai, comme c'est parfois le cas avec certaines machines industrielles de grandes dimensions; e) postes d'assistant occupés par des personnes non responsables du fonctionnement de la source soumise à essai, mais qui peuvent se trouver, occasionnellement ou en continu, à proximité immédiate de la machine; f) d'autres positions spécifiées, qui ne sont

Ta mednarodni standard določa metodo merjenja emisijske ravni zvočnega tlaka strojev ali opreme na delovnem mestu in na drugih bližnjih opredeljenih mestih v pretežno prostem zvočnem polju nad odbojno ravnino. Delovno mesto zaseda operater in je lahko locirano na prostem, v sobi, kjer vir, ki je preskušan, deluje, v kabini, pritrjeni na vir, ki je preskušan, ali ograjenem prostoru, ki je oddaljen od vira, ki je preskušan. Ena ali več določeni pozicij je lahko lociranih v bližini delovnega mesta, ali v bližini nadzorovanega ali nenadzorovanega stroja. Takšne pozicije se včasih omenja kot gledalske pozicije. Stopnje emisij zvočnega tlaka so določene kot A-ovrednotene stopnje. Poleg tega, če je potrebno, se stopnje v frekvenčnih pasovih in stopenj C-ovrednotenih vrhov zvočnega tlaka lahko določijo v skladu s tem mednarodnim standardom.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11201 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 1, Noise.
This second edition cancels and replaces the first edition (ISO 11201:1995), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 11201:1995/Cor.1:1997.
