Reduction of Aircraft Noise Measured in Several School, Motel, and Residential Rooms

Abstract

Field noise reduction measurements in 21 school, motel, and residential rooms during flyovers of jet and propeller aircraft are described. The measured noise reduction for most rooms was found to lie within or near the range of moderate noise-reduction values observed in previous measurements of houses and wood-frame air-base buildings. Sizeable differences in room noise reduction values were observed during successive aircraft flyovers. For jet-aircraft flyovers, the root-mean-square value of the standard deviations for noise-reduction measurements in school and motel rooms was 2.7 PNdB. For the four residential rooms studied, a root mean-square value for the standard deviations of 3.4 PNdB was observed.
