A Typical case study of school sound insulation

摘要

In order to mitigate noise due to aircraft operations associated with Manchester Airport, the Federal Aviation Administration (FAA) and the City of Manchester sponsored a sound-insulation program at Green Acres Elementary School. The sound insulation modifications included replacing windows and aluminum wall panels with acoustically-rated units, installing acoustical doors, installing upgraded ventilation, and installing new acoustical ceiling tiles. The Noise Level Reduction after sound insulation was 29 to 31 dB. This article summarizes the designs, construction process, ventilation system design and acoustical test results.
