art. no. 2022102

The article presents an idea how to increase the room acoustic absorption without significantly interfering with its appearance and architectural character. Based on scale model tests, analytical calculations and computer simulations, it has been shown that a noticeable reduction of room reverberation time and improvement of speech transmission index can be achieved by installing additional absorbing systems on selected furniture surfaces. By selecting the appropriate design and location of such systems, the functionality and appearance of the modified furniture can be maintained.
