Summary:

Rattle noise produced in the vehicle interior due to broadband excitation by road irregularities is a major concern with respect to driving comfort, and therefore has become one of the most important topics of acoustic development in recent years. A quantification id est measurement of this rattle noise is of fundamental importance for systematic development work and production control.Common noise level measurements (dB, dBA, et cetera ) do not represent the rattle character in the vehicle interior as revealed during initial investigations. To overcome this problem and to substitute the subjective assessment with a combination of measurable parameters, the psychoacoustic software AVL-EAR was applied to create an Interior Rattle Quality Index. Based on more than 40 different vehicles that have been subjectively assessed by approximately 70 test persons, the index was generated by means of multiple pair comparisons and statistics on measurement data. The index correlates appropriately with the subjective rattle impression, with correlation coefficients of about R = 0.88 for the individual vehicle categories
