BS EN ISO 11205:2009

This standard BS EN ISO 11205:2009 Acoustics. Noise emitted by machinery and equipment. Engineering method for the determination of emission sound pressure levels in situ at the work station and at other specified positions using sound intensity is classified in these ICS categories:

• 17.140.01 Acoustic measurements and noise abatement in general
• 17.140.20 Noise emitted by machines and equipment

This International Standard specifies an engineering method (grade 2 accuracy) to determine the emission sound pressure level of machines in situ, at the work station or at other specified positions, using sound intensity. It is an alternative to ISO 11201, ISO 11202 and ISO 11204 for in situ measurements. It is applicable to all kinds of test environments provided that the requirements on background noise and field indicators are fulfilled.

This International Standard is applicable to equipment emitting stationary broadband noise. The noise can differ between operational cycles and can be with or without discrete frequency or narrow band components.
