In the present study, we evaluated annoyance and the effects of noise on the health of bus drivers. For that, 200 bus drivers from a public transport company participated in a cross-sectional study. Annoyance and effects on health was measured with analog scale: Sleep quality, occurrence of tinnitus, headache, irritation, and annoyance from bus engine, traffic, and passengers. Data of age and working time of bus drivers also were obtained. For noise exposure, LA eq was evaluated in 80 buses. Statistical analysis consisted of mean, standard deviation, minimum, and maximum, Kruskal-Wallis test with post-hoc Dunn, one-way ANOVA with post-hoc Tukey and Spearman's correlation coefficient. Results indicate three groups of bus drivers (not annoyed: (N.A.), a little annoyed (L.A.) and highly annoyed (H.A.)). The group H.A. was younger and with less working time in relation to others, with a significant difference only for age. Regarding sleep quality, there was no significant difference. For results on the occurrence of tinnitus, headache and irritation after work, group H.A. had significantly higher means. Result of annoyance to the bus engine was significantly higher in H.A. than in L.A. and N.A. Annoyance to traffic and passengers, no significant differences were found, but the highest results were found for L.A., followed by H.A. and N.A. Equivalent sound pressure level in buses was above of the limit for occupational comfort. It was concluded that bus drivers has considerable level of noise annoyance and some health effects are perceived. The noise is a factor discomfort ergonomic that may cause effects on health of bus drivers. This study aims to evaluate annoyance and the effects of noise on the health of bus drivers. Cross-sectional study with buses and bus drivers. For that, 200 bus drivers from a public transport company participated in a cross-sectional study.

Statistical analysis consisted of mean, standard deviation, minimum and maximum, Kruskal-Wallis test with post-hoc Dunn, one-way ANOVA with post-hoc Tukey and Spearman's correlation coefficient. Results indicate three groups of bus drivers (N.A., a L.A. and H.A.). The group H.A. was younger and with less working time in relation to others, with a significant difference only for age. Regarding sleep quality, there was no significant difference. For results on the occurrence of tinnitus, headache and irritation after work, group H.A. had significantly higher means.

A poluição Sonora é consideradapelaOrganização Mundial da Saúde um problema de saúdepublica.Este artigo apresenta um estudo dos níveis de imissão sonora, a partir da análise espectral de frequências, no entorno dos edifícios do campus Centro Politécnico da Universidade Federal do Paraná (Campus III). A avaliação foi feita em concordância com o método apresentado na norma brasileira NBR 10151 de 2000, que dispõe sobre a Avaliação do Ruído em Áreas Habitadas, e os resultados obtidos foram comparados com os níveis limites constantes da norma e da Lei Municipal 10.625 de 2002 da cidade de Curitiba. O tempo de medição para cada ponto avaliado foi de 15 minutos. Foram utilizados quatro analisadores sonoros calibrados. Conclui-se, que, para uma área educacional, os valores dos níveis de pressão sonora estão acima dos limites estabelecidos pela NBR 10151 e pela legislação municipal. A análise do espectro de frequências do ruído no entorno do Campus, mostra que o mesmo é caracterizado por uma faixa larga de frequências, desde baixas até altas frequências. Considerando-se os níveis sonoros máximos LAmax e os espectros sonoros medidos e considerando o limite de 60 dB(A) estabelecido pela Lei Municipal de Curitiba 10.625, a faixa de frequências do ruído gerado está dominantemente entre 63 Hz e 12500 Hz.
