What Does 'Plainly Audible' Mean?

In legal terms, "plainly audible" usually means that a law enforcement officer can clearly hear the sound and identify its content (e.g., the rhythm, the bass beat, or the lyrics) without the aid of a microphone.

It is a subjective but legally upheld standard designed to be easy to enforce on the street. If an officer can hear your music, you are liable.

Check Your Volume Baseline

The Distance Rule

Most ordinances attach a specific distance to this standard. Common examples include:

• Vehicle Noise: Illegal if plainly audible at a distance of 25 feet or 50 feet from the vehicle.
• Residential Noise: Illegal if plainly audible inside a neighboring dwelling with windows and doors closed.
• Commercial Noise: Illegal if plainly audible at the property line.

Why Bass is the Culprit

The "Plainly Audible" standard is particularly dangerous for bass lovers. Low-frequency sound travels through car bodies and house walls with ease. Even if the lyrics aren't audible, if the rhythmic thumping of the bass can be heard at 50 feet, it meets the definition of plainly audible in many jurisdictions.

The Takeaway

Don't rely solely on decibel apps to keep you safe. The "Plainly Audible" standard is the real-world test used by police. If you can stand on the sidewalk 50 feet away and identify the song playing in your car or house, turn it down.
