St. Bernard, OH Noise Levels
Is St. Bernard, OH noisy?
St. Bernard, OH's 70-79.9 dB(A) band spans one of HUD's zone boundaries, so the honest answer is a range: somewhere between "Normally Unacceptable" (65-75 dB(A)) and "Unacceptable" (above 75 dB(A)), not one clean verdict. Road traffic drives that number here, not the other two sources.
