Concurrent sound and ventilation quality study in a moving machinery cabin

    Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientific


    The noise and air quality conditions in a moving machinery cabin are important for the machine operator. Both noise annoyance and ventilation-related issues have been addressed in earlier studies separately but not at the same time in one study. In this study both cabin sound quality related issues as well as air quality issues were addressed concurrently. First the conditions were recorded in field conditions. After that a series of laboratory experiments were conducted. These experiments included the assessment of generation of noise and pressure difference in different flow conditions as well as experiments with active noise control. The results show that an optimum for both pressure loss and generated noise in a ventilation system can be utilized in ventilation system design. Furthermore, the active noise control results showed it to be a feasible tool in diminishing the periodic components and changing the quality of perceived noise in a moving machinery cabin.
