FIELD: construction.
SUBSTANCE: invention relates to a sound-absorbing structure consisting of several sound-absorbing sections located in room (01) with walls and ceiling adjoining them from above. Several sound-absorbing sections arranged in a row form one or more sound-absorbing strips (03), which pass at least along part of joint between wall and ceiling of room (01). Width of sound-absorbing sections makes 200–400 mm, and thickness - 40–65 mm. Sound-absorbing sections have aerodynamic resistance varying from 5 to 20 kPa⋅s/m4. Invention also relates to sound-insulated room (01) with a similar sound-absorbing structure.
EFFECT: invention improves acoustic properties of the room in a wide frequency range, ensures sound absorption efficiency.
