GB/T 17248.2-2018 in English

This standard provides methods for determining the sound pressure levels at work positions and other specified locations caused by noise emitted from machines and equipment. It outlines procedures for measurements conducted in a semi-enclosed space where environmental corrections can be disregarded, assuming an approximate free field condition. The document specifies the necessary equipment, calibration procedures, and measurement conditions to ensure consistency and accuracy in noise assessments. It also includes guidelines for the selection of measurement points and the handling of data collected during the testing process. The standard is applicable to a wide range of industrial and commercial settings where noise measurement is required for compliance, safety, or environmental impact assessments. Detailed information on the measurement techniques and data interpretation is provided to support accurate evaluations of noise emissions.
