Investigation of noise level in Trakai city during day

Abstract

Measures of noise levels in the evening time determined that the highest levels of noise also as in day time were near main streets of the town and near night club „Salos“. Here the levels of noise varied from 57 to 62 dB, and the highest 75 dB equivalent level of noise was measured near the crossroad of the most intensive streets. The limit of noise level during night time exceeded only in one site near the exit of Trakai town, in the other sites the level of noise varied from 45 to 53 dB(A) and did not exceed the limit of noise level (55 dB(A). To compare the levels of noise in different times of a day, it is seen, that higher level of noise is measured in the evening time was 1,2 dB(A) higher than measures which were made during day time.
