4 <br /> <br />average is going to be between 100-157 dB. Those decibels are measured at 1.5 meters to up to 6 <br />meters away from the source of the sound. As sound travels, we know that the sound waves <br />expand. They bounce off of things. The further you get away from the source, the less likely will <br />be the dosimeter’s effectiveness. It will be difficult to test from the side of the road or at <br />someone’s residence what decibel level is being created by a firearm on a neighbor’s property <br />500 feet away. It might register, but it is going to register at a very low point. The Orange <br />County noise ordinance contains decibel limits, but a firearm is a sudden-impact source of sound <br />that will needanother type of device to catch its noise level. It is not as simple as using a meter at <br />the property line to get an accurate reading. I don’t think the Orange County noise ordinance <br />with the firearms exemption lifted would be enforceable because of all of this. The ordinance <br />refers at Section 16-53 (b) to “any continuous, regular, frequent, or intermittent source…” But <br />how often? If we can’t make those accurate measurements with a dosimeter then how are the <br />standards in the noise ordinance going to be enforcedin shooting situations?There are a lot of <br />things you have to consider once you start using these meters: distance, ambient air temperature, <br />moisture density in air. I’m leaning toward a distance restriction to get at the noise rather than <br />having someone try to measure the noise from a firearm. <br />Mr. Tilley said that a problem with enforcing against firearms noise using decibel measurement <br />is that the noise has to be present when the deputy arrives. Most often it is not.He agreed with <br />Mr. Kirland’s leaning toward a distance restriction. It would also help people to feel safer, he <br />said. <br />Dr. Arvik asked that “relentless” be removed from the problem definition for noise (“Relentless <br />shooting creating gunfire noise that is bothersome to neighbors.”). Itis a subjective term, he said, <br />and suggested “persistent” as a substitute. Mr. Tilley and Mr. Tesoro said the two words mean <br />the same thing. Other suggestions from the group were repetitive, continuous, ongoing, and <br />sustained. Mr. Tilley said all the suggested words were synonyms. Dr. Arvik said they did not <br />mean the same thing, and that if we do not choose the right words then lawyers later will <br />frustrate the Committee’s goals.Mr. Tesoro said that the firearms noise problem is like the <br />Orange County Speedway bothering some people. Different people consider different numbers <br />of rounds –one shot every day for a week to someone not comfortable with gunfire --as being as <br />relentless or persistent or ongoing. Law enforcement uses “sustained,” said Chief Sykes. <br />“Relentless” is a biased word, said Dr. Arvik. Ms. Barksdale said that “relentless” has an <br />egregious tone to it, while “sustained” is more objective. The group agreed on “persistent.” <br />Mr. Webster said that distance and time of day restrictions would give the Sheriff’s Office a <br />solid basis for enforcing against firearms noise. Anybody can measure those things, he said. But <br />we also need to decide whether we even need an ordinance. <br />In reply to a question from Ms. Conti, Chief Sykes said that the new digital noise meters being <br />acquired by the Sheriff’s Office operate on the same premise as the analogue meters currently <br />being used. The readings will be taken in the same way. Enforcement against firearms noise <br />using instrument readings is not going to be a feasible option, he added. Impact noise such as <br />gunfire has to be read differently. It is very difficult to capture that sound. There are two pagesof <br />requirements under the Orange County noise ordinance for taking measurements and <br />establishing certain facts. In my experience, when you go to court and there is this much
