AbstractA simple wood frame test house was constructed at Ottawa Airport and aircraft noises were recorded at locations in each of two test rooms and outdoors. The construction of the test house was systematically varied by changing interior surfaces and by adding windows. For some tests interior masking walls were added to limit propagation to predominantly through one of the exterior walls of each room. The measured octave band noise reductions were compared to predicted values from laboratory tests of exactly the same constructions. Ground reflections and internal flanking paths were found to influence results. When these were taken into account the mean prediction error was 3.1 dBA for walls without windows and only 0.5 dBA for walls with windows. The remaining errors were mostly due to differences in low frequency resonances between the laboratory and the field situations.
