This article presents the results of experimental investigations regarding infrasound pressure levels in commercial vehicles and passenger cars under differentiated conditions. The investigations come from measurements effected in specific conditions as follows: speed variation, cabin shape, windows and solar roof closed, totally and partially opened. Under the action of wind attack, the passenger compartment behaves sometimes like a cavity called Helmholtz resonator. The windows, the solar roof apertures and the volume are important parameters in this research. The infrasound levels as well the spectrum profiles are analysed under different conditions, and the results coming from passenger cars and commercial vehicles are compared. The time exposition is associated to the levels and some aspects concerning comfort and injury are discussed. According to performed measurements and subjective evaluations, one can conclude that infrasound increases annoyance, depending on how high the levels are. Under sharp peaks, like those produced by wind exitation through the solar roof of passenger cars, the test person feels the worst sensations that are very difficult to describe in words. This means that if one needs to worry about something associated with infrasound in vehicles, comfort is the right word.
