The Noise Assessment and Prediction System at Aberdeen Proving Ground, MD predicts noise intensities generated in surrounding communities by an ordnance test given a vertical profile of wind, temperature, and humidity. When the predicted sound levels are too high, the test is postponed until atmospheric conditions are more favorable to minimize the number of complaints. To determine the accuracy of the predictions, the users matched several hundred microphone measurements collected at 15 sites between 24 January and 31 March 1994 within the Aberdeen area to ordnance blasts and statistically compared the measurements with sound intensities predicted for the same locations. The results presented in this report show how well the measured noise intensities were predicted as a function of time of day, microphone location, and time difference between the atmospheric and microphone measurements.
