AB  - [Engineering Reports] The model of a panel with attached masses is developed and the modes of a distributedmode loudspeaker (DML) are analyzed with FEMLAB. The aim was to make minor modifications to the panel with properly attached masses which will be sufficient to improve its sound pressure response in a given frequency band. Based on the established model, a series of optimized positions of various attached masses is presented using genetic algorithm (GA). The corresponding sound pressure responses are also calculated using the FEMLAB. The attached-masses method (AMM) is verified by experimental investigations. The measurement results indicate that the AMM indeed improves the performance of the DMA with regard to its sound pressure response.
