Walford, IA Noise Levels
Is Walford, IA noisy?
Walford, IA's 60-69.9 dB(A) band spans one of HUD's zone boundaries, so the honest answer is a range: somewhere between "Acceptable" (65 dB(A) or below) and "Normally Unacceptable" (65-75 dB(A)), not one clean verdict. Road traffic drives that number here, not the other two sources.
