The purpose with this project is to give insight about the theory behind, and the usage of, membrane absorption. This was done in an effort to reduce a particular acoustical problem regarding a room mode which resonated strongly in my music studio and was causing trouble within the low frequencies. In this essay I go through the history, theory, making-of and results of said absorption technique, and explore the possibilities of it working as a relatively cheap and space efficient solution to problems regarding standing waves. The results were positive considering the low budget. The standing wave decay time was almost halved and the frequency response improved, which proves the capability of this type of absorption.
