The set of chambers can be used for:

• testing of sound insulating characteristics of panels with the dimensions up to 2,5x2,5 m²; 
• testing of the sound insulation of closed shells in a diffuse sound field;
• measurements of the sound insulating characteristics of different elements and panels used in automobiles for the purpose of the development of most efficient means for sound insulation and sound absorption;
• measurements of the acoustic power generated by different machines and mechanisms;
• certification tests of various instruments and equipment;
• estimation of the efficiency of passive means used for the sound insulation of different structures.

Main technical characteristics:

• the high-level chamber - area 4x9 m² with sloping ceiling elements,
  chamber volume 160 m³;
• the low-level chamber - area 4x4 m² with sloping ceiling elements,
  chamber volume 60 m³;
• the space for the construction elements under test - 2.5x2.5 m²;
• provision is made for an extra facility that allows testing of specimens with other dimensions;
• the low-level chamber for testing construction elements used in the ceiling structures - dimensions 3x3x3.5 m³, chamber volume 30 m³;
• the area of the equipment room of the chamber is 23 m².

The equipment room contains modern equipment made in Russia and in other countries. The equipment includes a personal computer, transmitting-receiving, analyzing, and recording devices, and acoustic sources generating a close-to-diffuse sound field in the chamber. All equipment is certified.

The high-level chamber and the vestibule of the equipment room are supplied with an overhead-track hoist of load capacity 2 t. to move the elements under test. The chamber and the vestibule have special gates for large-size elements.
All chambers are connected by communication lines.

The main advantages of the chambers is their large volume that allows the testing of a wide range of structures under strictly controlled conditions.
