When one is looking to protect persons (from noise) by the means of a structure envelopping a noise source (machine), designed for protecting the environment from this noise source (machine), ITS offers a wide range of acoustic hoods for many applications of soundprrofing / acoustic insulation related to the protection of workersagainst noise.

ITS offers powerful solutions at a reasonable cost in response to all the needs in the matter of soundproofing (preventive or curative) by the means of ergonomic equipment (standard or tailor made) for which the quality of design and of execution meets the highest level of requirement in this area for an efficient fight against noise in the context of compliance with legislation on noise at work or of improvement of working conditions.

The acoustic hoods offered by ITS allow the treatment at source of noisy machine and equipment.

The noise level ouside of such soundproofing devices is generally well below the lower values of exposure of workers to noise trigging action: a sound pressure level below 75 dBA can be obtained in numerous ordinary cases, offering in any cases to workers (including: operators of very noisy machinery) the protection against auditory trauma necessary for the performance of their tasks.

The acoustic hoods proposed by ITS can allways be disinstalled for a reinstallation in a different place.

They are usually made of coated metallic soundproofing panels with an insulation made of mineral fiber (wall, roof and if needed: floor) and equipped with painted metallic acoustic doors (rotating or sliding) and of acoustic windows with safety glass. Some of those construction elements may have a sound reduction index Rw that can reach 52 dB as a standard (a higher performance 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 reduction index according to the standards NF EN ISO 140-3 Acoustics - Measurement of sound insulation in buildings and of building elements - Part 3: laboratory measurement of airborne sound insulation of building elements and EN NF 717-1 Rating of sound insulation in buildings and of building elements Part 1: airborne sound insulation
  • 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

The acoustic hoods 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 acoustic hoods.
The verification can be conducted according to the standard NF EN ISO 11546-2: Acoustics - Determination of sound insulation performances of enclosures - Part 2 : measurements in situ (for acceptance and verification purposes).

Acoustic hood, soundproofing hood, soundproofed hood, acoustic hood for machine, soundproofed hood for machine, soundproofing hood for machine, noise hood: all equipment that one can source thanks to Isolation Technologie Services (ITS).

Such means of struggle against noise often form the basis for actions to improve working conditions in workshop and generally in premises hosting an industrial fabrication (whatever it is) where the sound environment is really under par or outdoors for sites where the implementation of noisy equipment e.g. fan-motor assemblies, dust collectors, can be a nuisance to neighbors.

Thus, many applications are possible to attenuate the noise emitted by machine tools (e.g. for industrial metal construction or for wood industry): motorized saws, lathes, milling machine, grinders, drill presses, planers , planing machine, and also to limit noise pollution from machining centers with several functions (with computer numerical control - CNC).

The modular constructions offered by ITS allow modifications and extensions required in case of changes in production methods. The access and removable parts are carefully designed according to constraints related to the operation and maintenance: the acoustic performance is always adapted to the context.
