摘要:
The results obtained from theoric and experimental studies on isolating systems are presented on this paper. This systems have been mounted in the Polithecnic University of Madrid, on a window 4.67 m wide and 1.94 m high which communicates two chambers: emitting chamber (114.6 m(3)) and receiving chamber (88.7 m(3)). The purpose of this work is to: Design systems with the highest possible isolation to airborne noise from experimental measurements and obtain conclusions for future improvements. Determain the efficacy of the existing equations comparing them to the experimental results. Obtain new equations in order to calculate the isolation to airborne noise with more precision.
