Dr. D’Antonio was an invited speaker at Koeln Messe, Cologne, Germany describing RPG’s research on the acoustic design of speech rooms in which the signal to noise ratio is maximized for good speech intelligibility. A book of the proceedings will be published in the coming year. This featured project illustrates the use of Canadian maple veneered Topakustik panels on the walls of a district office meeting room and 1500 m2 of planks on the side walls and ceilings of the entrance hall.Repost from RPG Facebook page
