When one is looking to develop a testing room, ITS offers a wide range of anechoic chamber for many applications of soundproofing / acoustic insulation related to the construction of anechoic rooms or of semi-anechoic rooms, as well as of aero-acoustic wind tunnels (aerodynamic wind tunnels).

ITS offers powerful solutions at a reasonable cost in response to all needs in the matter of acoustic measurement rooms (construction or retrofit) by the means of equipment whose quality of design and of execution meets the highest requirement level in this area in the context of R & D for acoustic comfort.

Theanechoic chamber offered by ITS allow to obtain free field conditions (when applicable: on a reflecting floor) meeting the requirements of standard NF EN ISO 3745 Acoustics - Determination of sound power levels and sound energy levels of noise sources using sound pressure - Precision methods for anechoic rooms and hemi-anechoic rooms.

They can allways be disinstalled for a reinstallation in a different place.

They are usually made of modular elements whith a geometry defined for each project, covered by a cloth (eventually: with a painted metallic perforated protection) with an insulation (filling) made of mineral fiber or of foam or of polyester fiber (wall, roof and if applicable: floor) that equip also (by the means of mobile sets) the places of acoustic doors allowing to access to the measurement room and the places of acoustic windows allowing the visibility from a control room.Some of those elements may have a sound absorption coefficient for normal incidence αo close from 100 % from 50 Hz (higher performance related to a lower cut off frequency can be obtained by the means of special constructions).

Regarding products and construction systems proposed by ITS their performance is measured in laboratory according to current standards:

  • their sound absorption coefficient according to the standards NF EN ISO 354 Acoustics - Measurement of sound absorption in a reverberation room and NF EN ISO 11654 Sound absorbers for use in buildings - Rating of sound absorption
  • their sound absorption coefficient for normal incidence according to the standard NF EN ISO 10534-1 Acoustics - Determination of sound absorption coefficient and impedance in impedance tubes - Part 1: Method using standing wave ratio

The anechoic chamber proposed by ITS can be delivered as a kit ready to assemble with assembly instructions or be installed turnkey.

A guarantee of acoustic performance on site is issued for each installation of anechoic chamber.

The anechoic chamber offered by ITS are robust constructions with quality finishes ensuring a high durability.

They are notably used in order to equip acoustics R&D laboratory (anechoic rooms and aero-acoustic wind tunnels in all fields of activity), for universities,engineering school, research institution.

The absorbing treatment for anechoic chamber offered by ITS are a choice acoustic lining as soon as it comes to quantify (in a laboratory) the noise emissions of noisy equiment or to develop equipments sufficiently silenced or having a particular sound design, that make use of specific testing rooms as for the automotive sector (anechoic rroms are called anechoid rooms sometimes).
