Product Code:SAE ARP4721/1
Title:Monitoring Aircraft Noise and Operations in the Vicinity of Airports: System Description, Acquisition, and Operation
Issuing Committee:A-21 Aircraft Noise Measure Noise Aviation Emission Modeling
Scope:This SAE Aerospace Recommended Practice (ARP) provides engineering methods that can be applied to monitoring aircraft noise and operations in the vicinity of airports using either attended or unattended monitoring systems, as well as methods for validation of measurement results from permanent systems. Part 1 provides guidance on the components, installation and administration of permanent systems and guidance on analysis of data collected from temporary monitoring of aircraft noise. A separate document, Part 2, describes both system screening tests and detailed test methods for validating the data reported by permanently installed systems. This document is intended as a guide toward standard practice and is subject to change with experience and technical advances.
