Emission sound pressure level measurement to verify a machine's declared noise values meet regulatory requirements, per ISO 11202.
Noise testing measures the emission sound pressure level at the operator's position and other specified locations around a machine, following standardised methods such as ISO 11202, and determines whether the declared noise emission values meet regulatory and harmonised-standard requirements.
Noise isn't just a comfort issue — sustained exposure above 85 dBA is a recognised occupational health hazard linked to permanent hearing loss, and the Machinery Directive requires manufacturers to declare A-weighted emission sound pressure levels in the instructions for use. Getting this wrong means either understating a real hazard to operators, or over-specifying costly noise controls that weren't actually needed.
Noise Testing applies wherever a machine's declared noise emission values need to be verified.
ISO 11202 sets the method for measuring emission sound pressure levels; ISO 4871 sets how the declared noise values are stated in the instructions for use.
Noise testing measures the emission sound pressure level at the operator's position and other specified locations around a machine, following standardised methods such as ISO 11202, and determines whether the declared noise emission values meet regulatory and harmonised-standard requirements.
Noise emission information is part of the Machinery Directive 2006/42/EC requirements: manufacturers have to provide noise emission information for their machines, and declared values should be backed by measurement. Prazamana's noise testing checks a machine's declared noise values, which supports the technical documentation for CE marking.
Prazamana offers noise testing that measures emission sound pressure level to verify a machine's declared noise values per ISO 11202. It can be booked on its own or together with EMI/EMC testing, LVD testing and stop time measurement, and alongside CE marking consultancy. Tell the team about your machine and destination market, and they will scope the right tests.
Machines that generate noise at the operator's position or in their surroundings, such as presses, conveyors, compressors, pumps, cutting and packaging machines, are the usual candidates, especially if you export to the EU and need to declare noise values. Please describe your machine to the team to confirm what is needed.
Tell us about the machinery and its destination market and we'll scope the testing.
