Sound quality metrics applied to road noise evaluation

Abstrakt

Road noise monitoring systems typically measure sound levels in specific time periods. The more insightful approach suggests to measure also the nature of noise. Sound quality of sounds such as car noise can be objectively evaluated by several parameters. One of them is psychoacoustic annoyance, described by loudness, tone color, and the temporal structure of sound. In this paper the assessment of several sound quality parameters, such as: loudness of time-varying noise, sharpness, fluctuation strength, and roughness, as well some additional parameters borrowed from the Music Information Retrieval area are presented. Then a comparison between parameter values obtained by means of the professional measurement system and a tool working in the Matlab environment is performed. The conducted investigations are carried out using recorded samples of an individual vehicle 1930 J. Acoust. Soc.
