Аннотация: Acoustic comfort is one of the main factors of a man's comfortable existence in the residence places. Over the past century, a lot of experience has been accumulated in isolating rooms from noise using enclosing structures, but the acoustic regime is deteriorating due to the constant increase in the power and number of noise sourceПоказать полностьюs in localities and buildings themselves. Therefore, acoustic comfort is not always provided in the premises even with satisfactory sound insulation of enclosing, as experimental studies have shown. In addition, humanity strives to build structures with the lowest material and labor costs. All this makes us look for more effective solutions for sound insulation and sound absorption. A sound-proof panel made of acoustic resonators ZIPAR is a plate of sound-absorbing material consisting of an outer sealed, sound-absorbing and sound-insulating layers. The air cavities of the sound-absorbing layer are made of upper parts-resonators, in the form of truncated cones, which cross-section decreases in the direction of the outer layer, and the cavities in the sound-absorbing layer have a cylindrical shape; these are the lower parts-deflectors. The data obtained as a result of tests are intended for use as a reference material in the design and installation of noise protection premises, both in new construction and in the reconstruction and minor repairs of existing buildings. © Published under licence by IOP Publishing Ltd.
