Acoustic Cladding and Panels
Hutchinson has more than 15 years experience in acoustics and all the necessary resources and equipment including very large anechoic rooms and reverberation rooms, coupled rooms, small booths, antenna systems, laser vibrometry, digital holography, measurement booths and robots, etc.
Hutchinson works in partnership with its clients in the field of the designing and manufacture of cladding, damping complexes and acoustic panels for transport means in highly demanding environments including aircraft, helicopters, ships, railroad, heavy trucks and construction or farm machinery.

Hutchinson designs improved systems for noise reduction, but also makes its own materials in specialized factories with the required specific properties including damping systems, high density flexible rubber masses, and silicone foams, all optimized for temperature ranges from - 50°C to + 70°C and conforming with fire standard FAR25-856. Hutchinson materials are optimized based on true material characteristics measured on instruments and on substructures under their broad operating conditions.
Our improved systems to reduce noise are generated from the CATIA model for the passenger compartment, acoustic reverberation models for the passenger compartment, « STL » (Sound Transmission Loss) specifications required on each panel so as to ensure the required acoustic performance at a given point in the passenger compartment (driver or pilot, passengers, etc.).
Hutchinson has developed its own optimization software, based on its long experience and measured characteristics on all available materials.
For a given thickness, the Soundproofing system is optimized by playing on the nature of materials, the number of layers and their layout, thus in order to maximize the STL and reduce at the same time the cost and the weight per square meter.
This photo shows a Soundproofing system; it shows an aluminum Deltane sheet (1) that damps the radiating surface and efficiently separates this surface from the multi-layer (2) including foams and glass wools.
The inner panel (3) is covered with a new silicone foam (4) with a high absorption coefficient so as to reduce the reverberation coefficient of the booth.
Thermoacoustic insulation blanket made from glass wool (1 and 2) and a rubber sheet (3) satisfying the fire standard FAR 25-856
Improved attenuation provided by an optimized design (light colors for Calculated and Measured) compared with a traditional design (dark blue).
