On side surfaces of several rafters, there are absorbing bands consisting of sound-absorbing sections. Between neighboring rafters with absorbing bands, there is a sound-reflecting roof section, a width of which exceeds an average height of rafters by at least two times. In addition, the present invention relates to a sound-absorbing structure of sound-absorbing sections located in a large room with walls and a roof, wherein the roof structure consists of several rafters and roof resting on them. According to the invention, on both side surfaces of several rafters, there are absorbing bands consisting of sound-absorbing sections located sequentially.
