Research on urban noise highlights impact on song birds

The urban parks studied had average noise levels ranging between 62 and 72 decibels (dB); squares, between 54.5 and 62 dB, and university campuses, between 53 and 58.5 dB. The lowest average levels were recorded in a protected natural area, where the measurement was 38.4 dB. The two cemeteries included in the study were quiet places as well, with an average of 45 dB.

Among the birds better adapted to urban conditions are various species of finches, sparrows and thrushes
