One of the most popular speed regulation implement is speed bumps. However, there are some problems with speed bumps as well - it has been noticed that speed bumps increase motor vehicle-induced noise. This article presents investigation on how speed bumps increase motor vehicle-induced noise. The investigations were carried out on Klaipeda and Vilnius streets during different time of the day and year. Bruel&Kjaer sound level meters type 2260 and 2270 were used to investigate how much noise is caused by vehicles passing different types of speed bumps. 收起
