The Evaluation of Conventional, Electric and Hybrid Electric Passenger Car Pass-By Noise Annoyance Using Psychoacoustical Properties

چکیده
Road traffic noise is one of the most prominent sources urban pollution. Recently, as a result electrification vehicles, lower levels are expected in areas at speeds below 50 km/h. The commonly used physical descriptor, A-weighted sound pressure level, does not sufficiently characterize perceived annoyance either combustion engine or electric passenger car pass-by noises. Psychoacoustical descriptors advantageous for characterization purposes. objective this study was to evaluate caused by from internal engine, electric, and hybrid cars using psychoacoustical properties. To achieve objective, following steps were conducted. First, binaurally recorded sounds 40 different brands with motorization presented subjects who indicated intensity their on quasi-continuous scale. Second, signal properties analyzed. Third, new index developed, based judgments properties, One novel aspects consideration only cars, but also cars. An acceleration idle target speed km/h selected situation, which differs those considered previous studies. results show that such loudness, tonality, roughness, fluctuation strength, very useful perception, single above mentioned situation. developed index, weighted combination chosen can be planning prevention measures.
