Technical sound insulation

Technical noise control: Efficient solutions for quieter surroundings

In technological and industrial settings, soundproofing has long been an important tool for lowering noise levels and improving the quality of life. In the ideal case, effective noise protection measures are already an integral part of the development process in vehicle construction, mechanical engineering and the design of production lines, among others. There is a rising demand for machines and devices that score with quiet operation. However, technical noise control measures can generally also be implemented at a later stage, in particular using sound insulation layers or noise control panels with both sound-insulation and sound-attenuation effect.

Based on our many years of experience, we can recommend the right product and the optimum solution for virtually any application. Various measures can be taken to significantly reduce noise in production halls, workshops, utility rooms and other industrial spaces. To achieve optimum soundproofing, there are various options and specific recommendations for different room types.

Applications of technical noise control

Technical noise control measures are applied in a variety of areas to solve noise problems and create a quieter and more pleasant environment:

Machines and systems:
Acoustic enclosures, sound-damping materials, acoustic cabins/casings as well as insulation layers help reduce noise generated by production machines.

Factories, workshops and production halls:
Sound-absorbing materials on ceilings and walls help keep noise levels low and improve working conditions.

Advantages of technical noise control

Health and well-being:
Quieter surroundings mean less stress - and minimized stress levels foster sound sleep at night and lead to overall improved health.

Productivity and efficiency:
Lower noise levels at work, whether in the office or in the production hall, support concentration and boost productivity.

Eco-friendliness:
Technical noise control measures help reduce harmful noise emissions and create a quieter environment.

Less structure-borne noise thanks to the effective acoustic insulation of enclosures

Mechanical devices and machines often are the source of structure-borne noise. Examples include motors, pumps, compressors and ventilation systems. These devices generate vibrations that are transmitted through their housings and then spread into the surroundings in the form of audible sound. Soundproofing machine enclosures is therefore an effective method of reducing structure-borne noise and creating a quieter working and living environment.

Vibrations and the resulting noise can be significantly lessened through the use of sound-attenuating materials, composite foam products or multi-layer materials consisting of foam and a heavy layer. This results in quieter and safer surroundings that support efficiency, both in industrial and domestic environments. With the high-quality sound insulation solutions from soniflex, noise pollution can be noticeably and sustainably reduced.

soni 1116 ALG
Thickness: 4 mm
soni 1116 ALG is a two-component material for heat protection and acoustic insulation: The heat-resistant surface layer is made from a high-quality aluminum foil and reliably reflects heat radiation. The bottom layer consists in a quilted glass fiber mat, which is responsible for the heat insulation effect as well as for the sound-insulation properties. Our soni 1116 ALG is optimally suited for use in the hot zones of vehicles and machines. When mechanically fixed, the acoustically effective insulation mat withstands temperatures of up to 600°C. The aluminum surface doubles as barrier preventing the penetration of oil, water and fuel. The material meets the fire safety standards for the automotive industry as set down in FMVSS 302 and DIN 75200. Simply use a carpet knife to cut soni 1116 ALG to the required size and shape. The optional self-adhesive rear face facilitates the installation of the panels.

soni 491 STL
Our soni 491/STL noise-control panel is a highly effective sound-insulation product based on PUR foam, equipped with a micro-perforated surface film and additionally with a heavy layer. This clever combination of two different acoustic materials ensures both sound-insulating and sound-absorbing properties in one product. soni 491 STL is suitable, for example, for boosting the sound insulation effectivity of a wall, partition wall or ceiling. Advice on building a curtain wall: For a curtain wall, dowel wooden laths of 30 or 50 mm thickness to the wall. Ideally, an elastic layer is placed between the wall and the laths to prevent sound bridges. Our soni NBR sealing tape is the ideal solution for such an elastic mounting. Then insert our sound-absorber product soni 491 STL in the empty spaces between the laths and cover them with plaster boards or particle boards screwed to the laths. To optimize the curtain wall you can "decouple" the plaster board / particle board from the floor and ceiling as well as the adjacent walls by filling the edge joints with acrylic.For an example of a curtain wall construction for noise insulation purposes, please see the testimonial "Neighbors / Curtain Walling”.  If you do not have the tools and/or the time to cover the sound-insulation panels with plasterboard or chipboard, we recommend our soni COMPOSITE as an alternative sound-insulation material. In contrast to soni 491 STL, soni COMPOSITE scores with a stylish decorative felt surface that is available in different colors and excellent for visible sound-conditioning materials.

Noise protection in production halls

Production halls usually accommodate a large number of machines and devices that emit a lot of noise, which constitutes a high stress factor for employees. A significant reduction of the noise level can be achieved with the help of our special acoustic products, such as soniflex soundproofing panels.

By building a noise-control enclosure around machinery areas and equipping the ceilings with high-quality and efficient sound-absorbing products from our range, you can significantly reduce the reverberation time and minimize the reflection of sound waves.

Noise control for machines

Compressors, production machinery and other equipment often cause excessive noise levels that become almost unbearable for employees. You can reduce these noise emissions by insulating machinery enclosures with our noise-control products.

In outdoor areas, machinery, technical systems or pumps can be “silenced” with
soni RESIST, for instance. For loud compressors we recommend our soni SB 700 compressor jacket..

There is a wide choice of noise-control solutions available, but for optimum sound insulation, the recommended option is to build special soundproofing enclosures that separate it from the rest of the room and shield off the noise source directly.

Technical noise control from soniflex

Especially in the technological context there are numerous sound sources and noise emitters that make it very unpleasant for people to stay in the vicinity. High sound volumes that – due to strong reverberation – cause a distracting or even upsetting noise level can quickly lead to physical and psychological problems.

We offer you numerous options for achieving sustainable noise reduction through targeted measures and customizable solutions. The soundproofing products from our range not only deliver on their promise in terms of noise reduction, but are also easy to install.
