This paper reports the results of a field experiment initiated by the Division of House Construction at Chalmers' University of Technology in connection with the Swedish Aeronautical Research Institute, whose primary aim was to study boom exposure effect on structures. Military aircraft were used which flew over a test area generating sonic booms of various intensities. Test persons were exposed directly under the flight path, the exposure effect being measured with the aid of a visual performance test and a tracking test. In addition, the subjective reactions of the test persons and military recruits, present at other sites under the sonic‐boom carpet, were evaluated with the aid of a questionnaire.
