Summary
Evansville's noise code names air conditioners and HVAC units as example sources on multi-use properties and sets the exterior wall of the receiving unit as the measurement line, folding HVAC noise into the general unreasonable-noise standard.
“Real property line” means either (1) the vertical boundary that separates one parcel of property (i.e., lot and block) from another parcel of property; (2) the vertical and horizontal boundaries of a dwelling unit that is part of a multi-dwelling unit building; or (3) on a multi-use property as defined herein, the vertical or horizontal boundaries between the two portions of the property on which different categories of activity are being performed (e.g., if the multi-use property is a building which is residential upstairs and commercial downstairs, then the real property line would be the interface between the residential area and the commercial area, or if there is an outdoor sound source such as an HVAC unit on the same parcel of property, the boundary line is the exterior wall of the receiving unit).
“Sound production device” means any device whose primary function is the production of sound, including, but not limited to, any musical instrument, loudspeaker, radio, television, digital or analog music player, public address system or sound-amplifying equipment.
“Unreasonable noise” means sound that is of a volume, frequency, or pattern that prohibits, disrupts, injures, or endangers the health, safety, welfare, prosperity, comfort, or repose of reasonable persons of ordinary sensitivities within the city, given the time of day and environment in which the sound is made.

Full Breakdown
EMC 9.30.010 defines a 'multi-use property' to include a parcel with boilers, elevators, air conditioners, or similar equipment that may be a source of elevated sound at another use on the same parcel. The same section's 'real property line' definition uses an outdoor HVAC unit as its worked example: where an HVAC unit sits on a multi-use parcel, the measurement boundary is the exterior wall of the unit receiving the sound. There is no separate decibel table for HVAC equipment; a homeowner's or business's unit is measured and judged against the general EMC 9.30.050(B) standard against unreasonable sound persisting 15+ minutes.
Violations & Fines
First violation is a formal written warning; second $50; third $150; fourth $500; fifth and subsequent violations $500 to $7,500 plus an order to cease using the device.
