ANALYSIS OF THE SOUND OF CARS WITH FOSSIL AND ELECTRIC DRIVEN BY PSYCHOACOUSTIC METHODS

One of the practical applications of psychoacoustics is the evaluation of sound quality. Sound quality assessment has been the domain of the music and audio industry for years. Driving comfort in cars is becoming an increasingly important demand of customers. In addition to many other properties, emphasis is also placed on oscillatory and vibrational acoustic properties -- the so-called HVP (Noise, Vibration, Transmission) characteristics of the vehicle. The article is focused on the assessment of psychoacoustic parameters in the interior of selected types of vehicles. Measurements were made on vehicles with gasoline, diesel and electric engines. Five psychoacoustic parameters were measured and a psychoacoustic head was used for the measurement. The measurements were carried out at different speeds and the measured values were processed and evaluated.
