Results are presented from a balloon-launch experiment to measure the effect of air pressure on sound transmission for various frequency ranges. Wireless transmitter/receivers mounted a fixed distance apart within a soundproof, but not airproof, enclosure measure attenuation of human screams as a function of altitude. The experiment was designed to provide real-time, qualitative data for the amusement of student observers, plus logged data from which the enclosed plots are derived. Balloon services were provided by Spaceport Indiana with a target altitude of 85,000 feet. The experiment was designed, conducted, and analyzed in just two weeks by a newlyformed student group called SEDS. After completion of the experiment, a brief survey showed a generally positive educational outcome for students involved in the project.
