Unincorporated Kane County relies on Illinois' statewide numeric noise limits, not its own decibel table. Under 35 Ill. Adm. Code 901.102, sound reaching residential (Class A) property must not exceed set octave-band levels, ranging from 75 dB at 31.5 Hz down to 40 dB at 8000 Hz by day.
Kane County does not adopt a separate decibel ordinance for unincorporated land; the binding numeric limits come from the Illinois Pollution Control Board. Section 901.102 sets maximum octave-band sound-pressure levels that any property-line noise source may emit to receiving residential (Class A) land. Daytime limits for a Class C (industrial) source to Class A land run from 75 dB in the 31.5 Hz band down to 40 dB at 8000 Hz. Nighttime limits are lower (about 69 dB down to 32 dB), giving stronger overnight protection. Measurements must follow ANSI standards using one-hour Leq averaging. These limits apply across Kane County unless a stricter municipal standard governs inside a city.
Exceeding the octave-band limits is a state noise-pollution violation enforceable by the Illinois EPA and Pollution Control Board; local disturbances are handled by the Sheriff.
