Abstract
A noise measurement study was conducted at five reservoirs in New York State during the winter and summer of 2003 to determine the sound power levels generated by some specific pyrotechnic devices (bangers, screamers, and CAPAs) using sound pressure techniques. The study was performed in support of an environmental impact statement (EIS) that defined the areas around each of these reservoirs where any significant impacts would occur as a result of the pyrotechnic operations. Sound characteristic data for each pyrotechnic device was collected at short distances with a direct line of sight to the pyrotechnic sources. The sound pressure levels for each pyrotechnic device were measured in two conditions (winter and summer) to examine the accuracy of measured data. The sound power levels, including both A-weighted and C-weighted 1/1 octave band values, were calculated based upon the measured sound pressure levels. With the absence of literature and manufacturing data supports, the values of this study were believed to be the most comprehensive emission data for the EIS noise analysis.
