Abstract A practical and repeatable method of assessing acoustic performance of vehicle carpet systems was developed and tested. The method was employed during in-situ tests to evaluate the vehicle carpet's sound absorption performance and transmission loss capability under stationary conditions. The acoustic performance of vehicle carpet systems was evaluated by introduction of floor mats. The resulting acoustic measurements were then compared and analysed. The various vehicle carpet systems are rated in terms of their effectiveness. Psychoacoustic analysis, using the Artemis software, was undertaken to evaluate the characteristics of interior cabin noise. The evaluation parameters include sound pressure level (SPL) in the entire frequency range, articulation index, loudness, fluctuation strength, roughness, sharpness, and tonality. Results indicate that loudness have the largest influence on sound quality.
