How Indianapolis decides what counts as too loud
Indianapolis builds its ordinance around a plainly-audible test applied to a person with normal hearing, paired with a set of overnight windows that vary by the kind of activity.

What's specific to Indianapolis
- The code repeatedly frames the test as audibility 'to a person with normal hearing', which sets the standard at ordinary perception rather than a meter.
- Refuse collection is singled out by container size, which is unusual and useful if the problem is an early bin lorry.
- Work in the restricted overnight window can be authorised in advance on application.
What Indianapolis residents most often report
- Amplified sound and parties audible from neighbouring properties after 10:00 PM.
- Construction and pile driving inside the 7:00 PM – 7:00 AM window.
- Early refuse collection, which has its own named provision.
How to measure it in Indianapolis
What Indianapolis needs is a record of when and where, not how loud. The tests turn on whether a sound was audible from a property other than the source between fixed hours, so timestamps are the evidence — a session that shows noise running from 11:40 PM to 1:15 AM sits directly on the 10:00 PM – 7:00 AM rule. Note the address you measured from, since the test is audibility at another property.
Record levels with the free online decibel meter, and log the date, start time and duration with each reading. A phone microphone is accurate to roughly ±2 dB and is not a calibrated instrument — enough to establish a pattern, not enough for an enforcement hearing.
Turn your readings into something you can file
Mayor's Action Center will ask when the noise happens and how long it lasts. A live decibel reading answers neither. Pro records a timestamped session — a ten-minute check or a full night — charts the whole thing, and exports a PDF with the dates, times, duration and the statistics that describe a pattern rather than a moment.
