How is Sound Measured?

Sound is measured by a weighted sound pressure level using a sound level meter and A, B, or C frequency weighting network.

For more information the American Standards Institute specifications are used.

A-weighting is used if not specified otherwise. A-weighting measures response of what the human ear hears cutting out lower and higher frequencies. It is general purpose measurements.

B-weighting is not commonly used and won’t need to be discussed.

C-weighting measures more to a humans response to a peak noise levels and some entertainment level noise measurements.

What Time is Noise Curfew in Bexar County?

There is no ordinance or specifically outlined law about a noise curfew in Bexar County outside of a city limits. This does not preclude a noise violation covered under Disorderly Conduct Chapter 42 of the Texas Penal Code.

Outside the city limits in Bexar County is similar to any county where a Texas Noise Nuisance would be covered by the state disorderly conduct statute. City ordinances apply within their own particular city limits only.

The Disorderly Conduct offense of noise covers unreasonable noise, not including a sport shooting range (defined in Local Govt Code 250.001), in or near a private residence that he or she has no right to occupy.

Important Note: Noise is presumed to be unreasonable if it exceeds 85 decibels after the person making the noise receives notice from a magistrate or peace officer that the noise is public nuisance.

Noise is defined in Texas caselaw to be loud, confused, or senseless outcry, or a sound noticeably loud, harsh, or discordant. That definition can include music.

Who Gets The Ticket?

At a private residence, during a violation, any adult, adult guest or adult trespasser who could control the level of noise can be cited if a resident is not present.

At a business any owner, manager, operator, employee or person operating the noise making device may be cited for the noise violation.

For unattended noise makers the person who leaves the noise making device, child or animal unattended is responsible.

San Antonio Noise Violation Fine

A violation of the San Antonio noise ordinance results in a fine. For a person with no intent to violate the noise ordinance the penalty is a Class C misdemeanor with a fine of $100-$500.

For a person who purposefully or even recklessly violates the San Antonio noise ordinance the fine is from $100 to $2,000. For a previous conviction the minimum fine becomes $200. After 2 previous convictions the minimum fine is $300 thereafter.

Each day’s violation is a separate fine.


A person or establishment will want to know the particular noise ordinance that applies to them. This can be a costly ticket or series of citations if given over multiple occasions.

The best protection is to purchase a decibel meter and periodically measure the sound at the edge of a particular property that could possibly lodge a complaint. Being proactive will always look better to a compliance officer. Take note of the recordings in case they are needed in the future.
