[quote=Anonymous]This is the real issue. And I could care less if the 12 apostles were riding them. They do not belong in the residential areas. Children are affected the most. Low income families are affected disproportionately because of where they live and where the ATV activity occurs. “Loud ATV exhaust noise has become an issue both medically and environmentally. The threshold of permanent hearing damage, as set by the OSHA, is 85 dB. A gas-powered lawn mower produces 85 dB. The snowmobile industry cannot, under U.S. law, exceed 78 dBs at full throttle, and since 1979 motorcycle manufacturers must stay between 78 and 84 dB. However, most ATVs are between 85 and 100 dBs, which has led to concerns by both riders and non-riders about excessive noise.” – How to Quiet ATV Exhaust Noise (A Practical Guide) How does one reduce the noise to 65 decibels at the property line? The answer is distance, but how much distance? Here’s a guideline: “Doubling the distance between the highway and residence will result in a noise level reduction of approximately 4.5 decibels, depending on the surface composition over which the noise is traveling.” So, at 50 feet from the property line, 95 decibels becomes 91. At 100 feet, it is 87. At 200 feet, it is 84 – at the threshold for permanent hearing damage. That IS the issue. [/quote]
