Urban noise is an important environmental stressor, and sleep disturbance is its major health effect. Substantial inter-individual variance in these effects might partly be explained by different sensitivity to noise. The aim of this study was to assess the effects of urban noise on sleep and the relation between self-estimated sensitivity to noise and sleep disturbance. A cross-sectional questionnaire survey was performed on 911 adult residents of Niš, Serbia, of whom 388 were men (42.6 %) and 523 women (57.4 %). The streets were regarded as noisy if night equivalent noise level (Leq) was higher than 45 dB(A) and quiet if night Leq was ≤45 dB(A). Noise sensitivity was measured with the Weinstein's Noise Sensitivity Scale. The study showed that respondents from noisy area significantly more often reported difficulty in falling asleep, being woken up, poor sleep quality, tiredness after sleep, and use of sleep medication than residents from quiet streets (p<0.001). Noise sensitivity significantly correlated with sleep disturbances (p<0.001). Gradska buka je važan ekološki stresni _inilac, a poremećaji spavanja su njezin najvažniji u _inak na zdravlje ljudi. Velika interindividualna varijacija ovih u _inaka može se djelomi _no objasniti osobnom osjetljivošću na buku. Cilj ove studije bio je procijeniti utjecaj gradske buke na spavanje i povezanost osobne procjene osjetljivosti na buku s poremećajima spavanja. Studija presjeka putem upitnika provedena je na 911 odraslih stanovnika Niša, Srbija, od _ega 388 muških (42,6%) i 523 ženska (57,4%). Upotrijebljen je upitnik o poremećajima spavanja. Osjetljivost na buku mjerena je Weinsteinovom skalom osjetljivosti na buku. Na osnovi rezultata mjerenja buke, ulice grada Niša ozna _ene su kao bu _ne noćni ekvivalentni nivo buke (Leq)>45 dB(A) i kao tihe noćni Leq≤45 dB(A). Studija je pokazala da su ispitanici iz bu _nih ulica izjavili da imaju zna _ajno više teškoća u uspavljivanju, više buđenja, slabiju subjektivnu kvalitetu spavanja, izraženiji umor poslije spavanja i da _ešće uzimaju lijekove za uspavljivanje u usporedbi sa stanovnicima iz tihih ulica (p<0,001). Osjetljivost na buku je bila zna _ajno povezana s poremećajima spavanja (p<0,001).
