The results of experimental studies of the sound insulation of fences with flexible slabs on the offset, carried out in reverberation rooms, are presented, and an analysis is made of the influence of some factors on their sound insulation. It is shown that the installation of flexible slabs on the offset from both sides of the main structure in the case of an air gap increases the additional sound insulation in relation to the one-sided arrangement of the slabs by 5–6 dB, and when the gap is filled with sound-absorbing material, this increase is 3–4 dB. The difference in additional sound insulation due to the use of layered vibration-damped elements compared to flexible plates connected “dry” does not exceed 2 dB with an air gap, and when the gap is filled with sound-absorbing material, it is equal to zero.
