In the midst of the coronavirus pandemic, more people are enjoying music at home, and noise complaints are increasing in densely populated areas. As a result, simple soundproofing rooms are also being sold. Here, soundproofing walls that reduce the sound in one direction only are focused on. Compared to the weight of 50 kg for commercially available simple soundproofing rooms, it is aimed for less than 14 kg that adults can easily carry around, and also making them foldable for normal use is considered. The diffraction of sound and the effect of double or triple walls are also taken into account, and how much weight and how much soundproofing are possible with the optimal combination of shape and material, using simulation and measurement of prototypes are examined.
