AbstractThis report compares measurements of the sound insulation of various constructions of a test house, exposed to aircraft noise at Ottawa Airport, with predictions from laboratory measurements of the same constructions. Further analyses investigated the major sources of the differences between laboratory and field measurements and corrections were developed for the IBANA-Calc sound insulation software. Source spectrum shapes for modern aircraft types were also developed for this software. The Ottawa Airport Test Structure (OATS) was a simple wood frame structure, representative of typical Canadian construction techniques, with two main rooms exposed to the noise from passing aircraft. The construction was systematically changed to include differences in wall and ceiling constructions, the addition of windows, and also the addition of various vents. In some tests, additional masking walls were added inside each room to simplify the situation so that sound transmission was predominantly through one of the outside walls. For each construction, the noise of departing aircraft was recorded outside in the free field and at the building façade as well as inside at 3 positions in each of the 2 test rooms.
