| Abstract | Anechoic rooms for acoustical measurements and research studies, must have properties of being free field, capable of soundproof and have low background noise. Due to their thick and heavy walls, they are usually constructed on ground floor or structures specially designed to handle the weight. Modification of an existing empty room on an upper floor of a high building to be an anechoic room is therefore very challenging, since it could destroy the building structure. This paper presents construction and verification of a hemi-anechoic room, built on the 5th floor of a nine story building. Composited walls consisting of wooden and gypsum, stuffed with sound-absorptive materials, metal sheets, and air cavities, were designed. Walls |
