Acoustic Quality Evaluation of Heavy Commercial Vehicles 2010-01-1411

In this project, developed together by IVECO and CRF, the goal of quantifying the perceived quality of the acoustic environment inside the truck cab was pursued. Based on considerable experience in connecting subjective response and objective acoustic data ([1], [2]), a solution was devised, by means of a statistical regression analysis connecting a very complete subjective testing survey (comparing field and laboratory tests) with a detailed investigation of psychoacoustic field measurements. Good correlation was found between field (ecological) and laboratory listening tests, so that it was possible to construct reliable perceptual models, composing both standard and custom-made psychoacoustic measurable items.
