Soundproofing carterisation

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 soundproofing carterisations 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 soundproofing carterisations offered by ITS allow the treatment at source of noisy machines 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 soundproofing carterisations 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 (walls, 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 carterisations 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 soundproofing carterisations.
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).

The soundproofing carterisations offered by ITS are robust constructions with quality finishes ensuring a high durability and sometimes also contributing to the limitation of other nuisances than noise: dust, fogs, fumes, heat, laser radiation ... Related features can be integrated (disassembly / mobility of the walls or of subsets, visibility, ventilation, lighting, securities, fire protection...)

The soundproofing carterisations offered by ITS allow the reduction of nuisance due to noise in all sectors of activity: - paper industry, corrugated cardboard industry: corrugators, processing machines and printing machines, mills ... - printing industry: rotary presses, extraction systems, crushers ... - metal transformation industry: stamping presses, punching presses, lathes, milling machines, other machine tools ...

ITS offers soundproofing carterisation for industry to protect workers against acoustic nuisance and noise pollution from production lines.

Acoustic carterisation, acoustic carterisation for machine, carterisation with high sound absorption, noise-reducing carterisation, soundproofed carterisation for machine, soundproofing carterisation, soundproofing carterisation for machine, soundproofed carterisation, soundproof carterisation for machine: all equipment that one can source thanks to Isolation Technologie Services (ITS).

Those devices, usually removable (thus to be both strong and light enough notably if the handling is performed without lifting device), are important for the protection of workers against noise and in addition, they ensure the necessary security with respect to machines or production lines dangerous organs (often: because in motion).

Their shapes can be very diverse to fit the needs, they are sometimes equipped with windows when visibility is necessary for an operator e.g. for driving a machine tool. The tightness of the carterisations offered by ITS always guarantee obtaining optimal performance particularly in terms of noise levels reduction at workplaces in the industrial sector.

Soundproofing enclosures are sold by ITS, depending on the context in relation to the machine, equipment, production line concerned:

• either to the original equipment manufacturer (OEM)
• or to a seller / integrator
• or to the end user

Whereas the design and construction are always part of the proposed supply (of course with the preparation of the associated documentation, including what concerns assembly instructions and maintenance manuals), the on-site installation can also be marketed (when the customer does not wish to take care of it himself, with an internal or external human resource of his choice):

• with the provision of a site supervisor, who guarantees the smooth running of the assembly operations, the respect of deadlines and the achievement of the expected acoustic performance (the customer then provides local labor, not necessarily hyper- specialist; this operating mode is often preferred by the customer for work on remote sites and/or when installation teams are already present in contexts where flexibility and speed of intervention are even more crucial than usual, or when the administrative formalities for the interveners are even more restrictive than usual, or to take into account planning peculiarities e.g. fractional work)
• with a complete service i.e. with the dispatch of a specialized assembly team (if required, handling means e.g. trolleys and scaffolding, cradles or platforms in the case of working at height can be rented to offer a turnkey solution)

Whatever the wishes of the customer with regard to their fitting (to be or not to be the one who carries out the installation: that is the question), the soundproofing carerizations offered by ITS are prefabricated in the form of kits, ready to be assembled according to a simple and detailed assembly procedure. In some special cases (e.g. prototype with variable particularities), a trial assembly before the hardware is made available is carried out in the workshop, e.g. when imposed by the Customer, whatever the reasons; an acoustic performance test (using a noise generator) is sometimes carried out on this occasion (provided that the geometry of the casing lends itself to it, i.e. when it is not perforated due to the absence of machines which support it or cross it, although tests are sometimes carried out in these cases too, then with closing of the openings which could otherwise cause sound propagation which would not be representative of the field).
