ISO1996
ISO 1996 is a series of international standards that specifies methods for the measurement of sound pressure levels relevant to environmental noise. The core of the series is ISO 1996-1, which defines the fundamental principles and procedures for determining the environmental noise. This includes guidance on the selection of measurement locations, the duration of measurements, and the frequency weighting to be used, typically A-weighting (dBA) for assessing noise perceived by humans.
ISO 1996-2 provides details on the survey methods for noise assessment. It outlines how to plan and
ISO 1996-3 addresses the specific requirements for the assessment of noise from airports. It tailors the general
