Noise

Noise is by deﬁ nition annoying. FiberAcoustic®_can

improve the working environment signiﬁ cantly due to the unique sound absorption properties.

To reduce noise exposure the noise should be shielded at the source, and reverberation time in buildings should be reduced. In working environments like ofﬁ ces, noise threshold limits are set to limit noise exposure. Sound absorbing materials must therefore be considered when building or renovating. When used in walls and ceiling structures, FiberAcoustic®_{provides unique sound}

absorption.

1. No loose ﬁ bres, and no face masks or gloves are required for handling. 2. Fibres are thermally bonded, preventing odour problems. 3. FR-treated ﬁ bres prevent coating ‘wash-off’. 4. Materials are recyclable. 5. Fibres create a porous structure that allows breathability. 6. Fibres resist extreme environments, providing long-time durability. 7. Products are very easy to install or process using existing tools.

The unique sound absorbing properties are second-to-none and controlled extensively using equipment certiﬁ ed by accredited test institutes.

_{– how it works}

Why air space behind FiberAcoustic

®

The space behind FiberAcoustic®_{is essential for the acoustic performance since it}

controls the frequency at which maximum sound absorption is obtained. Wide space provides absorption at low frequencies; narrow space provides absorption at high frequencies.

When a sound wave has entered the surface, the optimal acoustic impedance of FiberAcoustic®_{ensures that sound waves are encapsulated in the space behind}

FiberAcoustic®_{. Sound energy is removed by sound waves hitting back and forth}

between a solid surface and FiberAcoustic®_.

The space behind FiberAcoustic®_{consists of either air or ﬁ lling. With air as space,}

FiberAcoustic®_{ensures high acoustic performance, whereas ﬁ lling moves the}

absorption slope towards lower frequencies.

Air space/ﬁ lling: Air, mineral wool, highloft nonwovens

foam etc.

Solid surface: Wood, gypsum, stone, steel, glass, plastic etc.

Frequency

Sound level

What is sound

Sound is changes in the air pressure, oscillating around the atmospheric pressure. For the human ear, the important parameters are the frequency and the sound level. The frequency is measured in Hertz (Hz), and describes how many times per second the sound pressure oscillates around the atmospheric pressure. At low frequencies the sound is low (bass) and at high frequencies the sound is high (treble). The sound level is measured in decibel (dB) on a logarithmic scale, and describes the deviation in air pressure from that of the ambient atmospheric pressure. Typical conversation is measured to be 60 dB, an increase to 70 dB will be perceived as a doubling of the sound intensity.

How it works

When a sound wave strikes a surface of a material, it is either reﬂ ected or it penetrates the material. If the acoustic impedance of this material is too high, the sound waves are reﬂ ected and if the acoustic impedance is too low, the sound waves penetrate the material without being absorbed. At the proper acoustic impedance of the material, the sound energy will be absorbed and converted into heat by viscous friction between the oscillating particles of the sound medium and the structure of the porous nonwoven material. FiberAcoustic®_{is specially developed for optimal acoustic}

performance in human spaces provided by tuned acoustic impedance within a broad spectrum of frequencies.

Sound absorption

Sound is pressure waves travelling through air. Sound absorption is the absorption of sound waves in a material and is the process where sound energy is dissipated into heat energy. The sound absorption properties of a material are characterised by the sound absorption coefﬁ cient α, and vary from 0 to 1. Sound absorption of a material is frequency dependent.

α = 1.0 equals 100% sound absorption α = 0.0 equals 0% sound absorption

All FiberAcoustic®_{products are tested and documented according to EN ISO}

13501-1. All tests documenting the response to ﬁ re are performed by an external accredited test laboratory and full reports are available upon request in order to support architects, safety consultants and contractors.

The new standard EN ISO 13501-1 is considering three different aspects of response to ﬁ re: Fire resistance (B), Smoke development (s) and Burning drops (d). All FiberAcoustic®_{products are classiﬁ ed B-s1, d0 according to EN ISO 13501-1.}

At Fibertex Nonwovens, we have the capability and facilities to perform absorption tests according to EN ISO 10534-2. This method, known as the impedance tube measurement, is suitable for the initial testing of acoustic absorption properties and controls during production, as it provides rapid results to compare product performance. Products developed for large-scale commercial production are also documented in reverberation room tests according to EN ISO 354. These tests are performed by accredited third party laboratories, and reports are available upon request.

Automotive

Within the automotive industry sound absorbing materials are essential to obtain premium comfort. Fibertex Nonwovens is the leading European manufacturer of materials used in sound absorbing applications in cars. Typical product end uses:

• Lightweight products. Used in car roofs to reduce high-frequency noise.

• Heavyweight, needled PET fabric. Used in moulded wheel arches to reduce tire noise.

• Facing fabrics for bonnet insulation to reduce engine noise.

• Cotton composites for use in carpet moulding to reduce noise from car bottom.

Flooring

In hard fl oor applications, Fibertex Nonwovens has for many years supplied needlepunched nonwoven materials that provide foot step dampening. Products are used with or without moisture barrier foil and overlapping seams. The products are user-friendly and durable and compensate for minor unevennesses in the subfl oor construction. The effi ciency is well documented through test.

Construction

In the constructions of buildings where concrete slabs are used to separate the individual stories, two layers of Fibertex nonwovens are used in between the slab and the cast concrete ﬂ ooring to reduce noise transported through the construction.

(19)

Furniture

Fibertex Nonwovens can offer you professional advice on how to incorporate acoustic materials in your furniture, which will differentiate and add value to your business. Typical applications include ofﬁ ce screen walls, sound absorbing surfaces on the back of bookcases and surfaces underneath desks and sofas. Materials can also be used for decorative wall coverings, offset inkjet printing or unique paintings.

Porous absorbers

To reduce weight or minimise the environmental impact, traditional foam absorbers can be substituted with high loft nonwoven materials based on virgin ﬁ bre material or reused material. This is typically used in household appliances or industrial applications where the weight-performance ratio is of major importance. High loft ﬁ bre absorbers can also be equipped with self-adhesive glue to ease installation.
