HJ, Don't worry too much about a meter. Craig has one for Stony Pond. Just put some mufflers in your tool box just in case. Carey Lake and Elmira follow IMPBA noise recommendations:
Noise Rule
At all IMPBA sanctioned events all boats MUST meet the following conditions, and boat operators accept the included mandates.1. A commercially available noise measurement device (Radio Shack or equivalent) must be used. The noise measurement device will be set to the "A" weighted measuring scale, fast response.2.The maximum allowed dB level for IMPBA Sanctioned events will be 92 dB.
3. Measurements must be made from the shoreline area, between buoy #6 and the starting line. The measuring device will be set at a minimum height of 4' to 6' above the ground, with the device pointed approximately 90 degrees to the running path of the boats 25 feet back from the waters edge*. Stable mounting such as a tripod is strongly recommended. Care should be taken to assure the operator of the measuring device is in a safe location.
With an internal stinger and an add on muffler most of us are in the mid-to low 80db range. RC
