Environmental noise modeling, quality control, verification, and validation concepts

Abstract

Over the past 30 + year's noise modeling has developed in all engineering fields. ISO 9001 has developed detail simulation validation criteria's for variouse engineering fields. Engineering software application for environmental noise modeling are just one of many fields that offer advanced simulation options. Unfortunately, the validation of environmental noise simulation is still under development. With the increase of environmental noise projects the model validation between test and simulation is scrutinized by the public or in court. The presentation discusses the definition of Model, Mathematical Model, Computational Model and Conceptual Models and the definition of Verification, Validation and Updating. What are the tools for quality assurance (QA) for the noise modeling software, software verification and project quality control (QC)? What is the state of noise modeling standards in North America? What are the uncertainties and variabilities that the environmental noise engineer can control? Are we sure that we are modeling a worst-case scenario? What can consultants do to improve the quality of noise simulations.
