Workplace Noise Safety Standards

Workplace Noise Safety standards address potentially harmful or distracting noise at workplaces that are relatively low-noise. Office environments, while certainly quieter than a construction site, still constantly subject employees to significant levels of noise, especially since office employees don’t generally wear hearing protection. The combination of background chatter, printers or other machinery, and other human activities such as movement combine to create a noise level that, while unlikely to lead to damage, is capable of affecting concentration, and therefore productivity. Furthermore, isolated sources of loud noise such as server rooms present another challenge. Workplace noise safety standards guide the planning of office layouts, appropriate material selection for walls and ceiling, and the prediction of future noise levels.

ANSI/ASA S12.19-1996 (R2011)
Measurement of Occupational Noise Exposure
The standard presents methods that can be used to measure a person's noise exposure received in a work place. The methods have been developed to provide uniform procedures and repeatable results for the measurement of occupational noise exposure.

BS EN ISO 11690-1:1997
Acoustics. Recommended practice for the design of low-noise workplaces containing machinery. Noise control strategies (British Standard)
This part of ISO 11690 outlines strategies to be used in dealing with noise problems in existing and planned workplaces by describing basic concepts in noise control (noise reduction, noise emission, noise immission and noise exposure). It is applicable to all types of workplaces and all types of sources of sound which are met in workplaces, including human activities. It includes those important strategies to adopt when buying a new machine or equipment. This part of ISO 11690 deals only with audible sound.

BS EN ISO 11690-2:1997
Acoustics. Recommended practice for the design of low-noise workplaces containing machinery. Noise control measures (British Standard)
This part of ISO 11690 deals with the technical aspects of noise control in workplaces. The various technical measures are stated, the related acoustical quantities described, the magnitude of noise reduction discussed and the verification methods outlined. This part of ISO 11690 deals only with audible sound.

BS EN ISO 11690-3:1999
Acoustics. Recommended practice for the design of low-noise workplaces containing machinery. Sound propagation and noise prediction in workrooms (British Standard)
Deals with sound propagation together with the prediction of sound pressure levels at the workplace. Contains recommendations concerning the use of noise prediction as an aid for noise control.

Deals with sound propagation together with the prediction of sound pressure levels at the workplace. Contains recommendations concerning the use of noise prediction as an aid for noise control.

ONORM EN ISO 11690-1:1997
Acoustics - Recommended practice for the design of low-noise workplaces containing machinery - Part 1: Noise control strategies (ISO 11690-1:1996) (FOREIGN STANDARD)
Diese ÖNORM beschreibt Verfahren, die bei Lärmminderungsmaßnahmen an Arbeitsplätzen, in Arbeitsräumen und im Freien berücksichtigt werden müssen. Diese ÖNORM trifft nur für Schall im Hörbereich zu.

ONORM EN ISO 11690-2:1997
Acoustics - Recommended practice for the design of low-noise workplace containing machinery - Part 2: Noise control measures (ISO 11690-2:1996) (FOREIGN STANDARD)
Diese ÖNORM beschreibt Verfahren, die bei Lärmminderungsmaßnahmen an Arbeitsplätzen, in Arbeitsräumen und im Freien berücksichtigt werden sollten und befaßt sich mit technischen Aspekten der Lärmminderung in Arbeitsstätten. Es werden verschiedene technische Maßnahmen angegeben, entsprechende akustische Größen beschrieben, das Ausmaß der Lärmminderung diskutiert und Nachprüfverfahren dargelegt. Diese ÖNORM trifft nur für Schall im Hörbereich zu.

ONORM EN ISO 11690-3:1999
Acoustics - Recommended practice for the design of low-noise workplaces containing machinery - Part 3: Sound propagation and noise prediction in workrooms (ISO/TR 11690-3:1997) (FOREIGN STANDARD)
Diese ÖNORM befaßt sicht mit der Schallausbreitung in einem Raum und der Vorausberechnung der Schalldruckpegel und der Geräuschimmission an einem Arbeitsplatz. Die Einzelheiten der Beschreibung physikalischer Phänomene, die einem Schema zur Schallvorausberechnung zugrunde liegen, hängen stark von der betrachteten Situation ab sowie von der Art und Weise, wie diese Situation im Modell dargestellt wird (Eingangsparameter, Rechenverfahren). Es wird diese Abhängigkeit erörtert und die Methodik der Schallvorausberechnung beschrieben. Für die Anwendung der Schallvorausberechnung als Hilfsmittel zur Lärmminderung in Arbeitsräumen werden Empfehlungen ausgesprochen.
