Kokomo, IN Noise from Specific Sources: Low-Frequency Bass Limits (2026)

Kokomo Code of Ordinances § 132.03(B)(2) bars operating a radio, musical instrument, phonograph, or other sound-producing device in a manner that disturbs the peace, quiet, and comfort of neighboring inhabitants, or at a volume louder than necessary for convenient hearing by a voluntary listener inside the room, vehicle, or chamber where it plays. The section sets a concrete evidentiary test: operating such a device so it is plainly audible at a distance of 50 feet from the building, structure, or vehicle where it is located is prima facie evidence of a violation, which covers bass-heavy car audio and home stereo systems even without a decibel reading.

Paragraph (3) separately bans playing a radio, loudspeaker, or sound amplifier so the sound is cast onto public streets for commercial advertising or to attract public attention to a building. The code does not carve out a distinct low-frequency or subwoofer standard; the 50-foot audibility and general disturbance tests in (B)(2) are the operative rule for any sound-system noise, including bass. The alternative 83 dB(A)-at-15-feet threshold in § 132.03(B)(11) can also apply if a reading is taken.
