Download Effect of External Pressure Environment on the Internal Noise Level Due to a Source Inside a Cylindrical Tank - National Aeronautics and Space Administration | ePub

A small cylindrical tank was used to study the effect on the noise environment within a tank of conditions of atmospheric (sea level) pressure or vacuum environments on the exterior. Experimentally determined absorption coefficients were used to calculate transmission loss, transmissibility coefficients and the sound pressure (noise) level differences in the interior. The
