In order to be included in the study, participants had to be more than 20 years old and have no medical conditions besides musculoskeletal disorders or back pain. In total, the researchers looked at data from 65,533 participants who drove trucks or buses in Isfahan province, a city with high traffic in the center of Iran, between February 2006 and March 2016.

While much research has been done on how noise pollution affects those who live in the area, not a lot has been done on the effect noise has on the drivers themselves. The noises produced by vehicles can affect both those who are driving them and those who live around heavily traveled roads. The faster the vehicle is going, the louder the sounds are.

Cars measure around 70-80 dB, while busses can reach as high as 80-95 dB. Sound from vehicles is the most common source of sound people are exposed to on a daily basis.
