Abstract
An optimization study of Aluminium Extrusion for minimum sound transmission in low frequency band (50 Hz~1 200 Hz), subject to the constraints on the Weight is presented. Taken the thickness of each layer as design variable, with the use of Mixed Integer Programming Algorithm, minimized value of transmission power and corresponding thickness are obtained. Results show that sound power transmission is reduced and sound transmission loss is increased above 600 Hz.关键词
