||The noise level for urban bus drivers in Curitiba (Brazil) was evaluated in three types of buses: bi-articulated, speedy, and feeder. Measurements were made in 20 buses of each type. Bi-articulated buses are formed by three sections and two articulations. They operate in reserved lanes and stop at specific stations. Speedy buses operate in regular streets across the city, but they stop at fewer stations than other buses. Feeder buses operate normally in the whole city and call at all bus stops. The evaluation of noise levels in the workplace of bus drivers was performed according to ISO and Brazilian Standards. In 56 out of the 60 buses examined, the normalized noise exposure levels were below 82dB(A). The overall quality of the workplace was thus considered acceptable. Other findings are discussed.
