DOI: 10.1121/1.4988658
Abstract: More than 20 years after the first applications of micro-perforated sound absorbers in architectural acoustics there still is a growing demand of optically transpatent sound absorbers. Based on the theory of micro-perforated panel sound-absorbing constructions… read more here.
