Abstract

In this paper, measurements of interior noise in buses that serve Curitiba, Brazil are carried out to evaluate the noise level exposure of bus drivers. Two measurements, the first close to the driver and the second at the back of the bus, were taken inside 25 buses of various types. In 23 buses, the noise exposure of drivers was acceptable according to the definition of the Occupational Health Standard of the Brazilian Ministry of Labor. On the other hand, the normalized exposure levels were over 65 dB(A) in all cases, making the work environment "uncomfortable" according to the Brazilian Legislation for Ergonomics. Exposure was found to be highest in older buses and when engines are located at the front of the bus.
