The basis for establishing a comprehensive noise abatement plan for a plant is to first precisely determine the noise emission levels at the site. Laborelec pays particular attention in the selection of a measurement method that is optimally suited to the specific field characteristics present. Our measurements of the acoustic power of a source are performed in accordance with the ISO3741 and ISO3747 standards. Measurements by intensity metering are performed in accordance with the ISO 9614-1,2,3 standards.
