Diagnosis of a situation in terms of acoustics

The diagnosis of a situation in terms of acoustic by ITS is based on a long experience of confrontation with issues having a wide variety (but occurring with some repetition) in relation to acoustic insulation.

This diagnosis may include examination of manufacturer drawings and data, or analysis of acoustic measurements made by others if they are already available: ITS can take over studies performed by control offices or engineering teams either specialised or not (ITS is not intended to compete with them) and particularly action plans performed by others. If needed ITS can perform (promptly) complementary sound records (possibly with spectral analysis) to quantify the noise emission of an equipment or characterize the performance of a construction. ITS can perform other statements and investigations on site (site conditions, accessibility, operating constraints, environment ...).

This task may necessitate the performance of acoustic measurements analysis reports (for measurement performed by ITS or not) or of acoustics calculation sheets: cf. below in the same page.

With respect to such missions performed on its own behalf, ITS has taken out an "overall designer" insurance including notably the operation civil liability insurance, the professional civil liability insurance, and the compulsory insurance of decenal liability.

From the diagnosis of a situation in terms of acoustic by ITS it results an exhaustive explanation of the data taken into account, as well as of various related constraints and a performance target in terms of acoustics appropriate to the considered situation for avoiding acoustic nuisance.

Acoustic measurement analysis reports, acoustics calculation sheets and sizing sheets of soundproofing equipment

The preparation of acoustic measurements analysis reports, of acoustics calculation sheets and of sizing sheets for soundproofing equipment can be performed by ITS either in accordance with some standards (French or international), or in accordance with the methods of engineering associations (French or international), or based on developments made in-house.

Most of the software allowing acoustic predicting computation at ITS have been developed internally, which allows the integration of experience data complementing the best theoretical approaches of all times carefully selected in order to base the simulation models. (1) (2) (3) (4)

1 in terms of acoustics essentially
2 acoustic multilayered structures: partitions or absorbent linings and dissipative silencers: low or high temperature ...
3 enclosures, screens, laggings, suspended acoustical ceilings, wall cladding for reverberation treatment of rooms...
4 calculations of sound propagation indoor or outdoor, and from inside to outside of a building ...

With respect to such missions performed on its own behalf, ITS has taken out an "overall designer" insurance including notably the operation civil liability insurance, the professional civil liability insurance, and the compulsory insurance of decenal liability.

The preparation of acoustic measurements analysis reports by ITS allows (depending on the case) the characterization of the noise emission of an equipment or of an installation, the determination of the acoustic properties of a material or of a construction system, the quantification of the performance of a construction or of a room in terms of insulation.

See the list of calculations possible by ITS in relation to the analysis of acoustic measurements

  • calculations in relation to the determination of sound insulation performances of enclosures: according to measurements on site
  • calculations in relation to the determination of sound power levels of facilities for the evaluation of sound pressure levels in the environment
  • calculations in relation to the determination of sound power levels emitted by noise sources from the sound pressure
  • calculations in relation to the determination of spatial sound decay in industrial premises, tertiary premises and in subsets of buildings
  • calculations in relation to the determination of reverberation time in industrial premises, tertiary premises and in subsets of buildings
  • calculations in relation to the measurement of sound absorption in a reverberation room
  • calculations in relation to the measurement of sound insulation in buildings and of building elements
  • calculations in relation to the measurement of the performance of ducted silencers: insertion loss, flow noise and total pressure loss

  • calculation of the attenuation of sound during propagation outdoors (including: calculation of atmospheric attenuation)
  • calculation of the acoustic performance in buildings from the performance of elements: acoustic absorption of rooms and enclosed spaces
  • calculation of the acoustic performance in buildings from the performance of elements: sound insulation between premises
  • calculation of the acoustic performance in buildings from the performance of elements: insulation from noise coming from outside

The writing of sizing sheets by ITS allows the exhibition of evidences of the choices of soundproofing equipment (of those the implementation is compatible with the data taken into account as well as related constraints and meets the objective of results in terms of acoustics) involving a selection of products and of construction systems having the performance the most appropriate for the considered situation.

Definition of the means of prevention of nuisance and search for solutions in relation to a situation in terms of acoustics

The definition of means of prevention of nuisance and the search for solutions in relation to a situation in terms of acoustics by ITS is based on the consideration of the technologies being the most appropriate to the considered situation, for an optimal choice of the means that should be considered depending on the context (in particular accounting if any related features of the equipment and acoustic insulation systems and the constraints and consequences of all types generated by their implementation).

This task may necessitate the performance of acoustics calculation sheets and of soundproofing equipment sizing sheets: cf. above in the same page.

With respect to such missions performed on its own behalf, ITS has taken out an "overall designer" insurance including notably the operation civil liability insurance, the professional civil liability insurance, and the compulsory insurance of decenal liability.

From the definition of means of prevention of the nuisance and the search for solutions in relation to a situation in terms of acoustics by ITS it results the choice of soundproofing equipment (of those the implementation is compatible with the data taken into account as well as related constraints and meets the objective of results in terms of acoustics) involving a selection of products and of construction systems having the performance the most appropriate for the considered situation.

Brokerage for the supply of soundproofing materials and equipment

The experience of the human resource of ITS in the past 20 years has allowed to learn to know and appreciate in a positive way material producers and soundproofing equipment manufacturers with which ITS has developed a partnership - often exclusive - in France.

To meet the needs of soundproofing materials and equipment of its customers, ITS can offer (after the diagnosis of a situation in terms of acoustics and / or in the context of the search for solutions in relation to a situation in terms acoustics) products and construction systems (often with an international reputation) carefully selected by ITS for their relevance with respect to the considered objectives, to the guarantees offered in terms of quality of equipment and service and also for their reasonable price.

A guarantee of acoustic performance is issued for each delivery of soundproofing products or construction systems.

ITS then acts as a commercial agent, acting as a technical sales interface with the supplier (partner of ITS) who has all the qualifications and insurances required for the envisaged supplies, who provide all the guarantees of compliance with the rules of Art which are of his specialties and who provides billing and after sale service.
