Integrated Noise Model – A computer model for evaluation of aircraft noise impacts in the vicinity of airports
ManufacturerATAC (Aviation Analysis Experts), VNTSC (Volpe National Transportation Systems Center) i FAA (Federal Aviation Administration), USA Year: 2013.
Licence type and number: Educational – permanent ,Price of licence: Paid – no aditional fees
License expiration date Unlimited
Purpose: The Integrated Noise Model (INM) is a computer model that evaluates aircraft noise impacts in the vicinity of airports. The INM can output either noise contours for an area or noise level at pre-selected locations. The noise output can be either exposure-based, maximum-level-based, or time-based. The INM has many analytical uses, such as: Assessing current aircraft noise impacts around a given airport or heliport;Assessing changes in noise impact resulting from new or extended runways or runway configurations;Assessing changes in noise impact resulting from new traffic demand and fleet mix;Evaluating noise impacts from new operational procedures;Evaluating noise impacts from aircraft operations in and around National Parks.
