Acoustic Quality

Slovak State Health Institute is responsible for dealing with the problem of noise pollution. According to the 1997 statistics on noise pollution, this was monitored in 46 towns and villages with the total population of 1 357 598. Railway traffic impact was tested only in the town of Trnava (71 783 inhabitants).

Percentage of population affected by road and railway traffic noise based on the equivalent noise levels (L Aeq) excess in dB (A)

Source: ŠZÚ SR Noise level of 65 dB (A), as given by results of medical research, represents a level where negative impacts on human autonomic nervous system start. According to the Regulation of the MZ SSR No.14/1977 Coll. allowed noise limits are as follows: 60dB (A) - day time and 50dB (A) - night-time
