The paper presents the results of a pilot cross-sectional study focused on subjective traffic noise annoyance and sleep disturbance among the residents living close to major inner city corridors in several Slovakian towns including the capital Bratislava. The subjective adaptation to traffic noise, subjective evaluation of health status were assessed as well. The questionnaire survey was distributed to the pilot sample of 543 respondents (average age 45,3 (73,1% respondents from 35 to 65 years), 57% females, 71% living in houses more than six years). The inhabitants with bedroom windows facing noisy streets or quite streets represented the exposed and the control group. Road traffic noise annoys significantly more daily and night activities of respondents in the exposed group, who are unable to adapt to it (OR=5,28; 95 % CI=3,56−7,86 for sleep disturbance).The questionnaire was supplemented by traffic noise-measurements in Bratislava on noisy facades (LAeq,day = from 57 dB to 72 dB, LAeq,night= from 52 dB to 62 dB) close to major streets with intensity transport from about 16000 to 38000 vehicles per day. After completion of the results, we plan to propose interim measures to new apartment buildings as well as intervention procedures.
