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 conduct noise surveys, including sampling strategies and the statistical analysis of measured data to characterize noise levels over time. This standard is crucial for understanding long-term noise exposure and its potential impact.

ISO 1996-3 addresses the specific requirements for the assessment of noise from airports. It tailors the general measurement principles to the unique characteristics of aircraft noise, considering factors like flight paths and operational procedures. This part of the standard is essential for managing noise pollution in areas surrounding airports. Collectively, the ISO 1996 series provides a standardized framework for acousticians, environmental agencies, and policymakers to consistently measure, assess, and manage environmental noise, facilitating comparisons and promoting effective noise control strategies worldwide.
