In this study, the authors evaluate the usability of noise maps generated by students. There are several applications created for collecting crowdsourced noise data to generate noise maps. These applications enable scientists to use the capacity of community, although the raw data is not accessible. In this study, noise maps generated from unprofessional measurements were compared to official maps. The study confirmed that the smartphone applications tested are not capable for scientific measurement; however, tendencies suggest that calibration may lead to reasonably accurate noise level capture. The study also revealed that different mobile applications produce different outputs. This type of user generated noise measurements cannot substitute professional surveys, but provide additional data for strategic noise mapping and monitoring.
