REDUCING NOISE AND VIBRATION IN DAILY LIFE
Silencions is engaged in comprehensive cooperation with industry in the field of noise and vibration reduction, as well as in handling projects concerning measurement, research, and production of acoustic adaptations.
Silencions’ technology is not only based on the acoustic properties of the material itself, but also on the geometry of the structure and its periodic character. This means that our adaptations, depending on the customer’s expectations and needs, can be based on transparent, non-flammable, very light and non-thermal insulating materials. Their advantage is the ability to reduce noise and vibration even in the low frequency range, while maintaining low weight and volume of the material.
The use of classical and commercially available solutions enforces to choose between low mass and dimensions of the adaptation and its effectiveness in reducing low frequencies. Silencions, using its knowledge and many years of experience of its employees, designs structures which combine both desirable features and provide expected results.
Our mission is to bring silence back into everyday life. We strive to provide comfort at home and at every workplace. The wide spectrum of acoustic adaptations we offer ranges from soundproofing offices and apartments to industrial noise and vibration suppression. We provide services for a variety of industries such as aerospace, automotive, heavy equipment and household goods. To learn more about our technologies, please visit the next tab.
Our solution is perfect for:
Washing machines, vacuum cleaners
food processors, dryers, etc.
Generators, compressors, etc.
Machines that are part of assembly lines
Jigsaws, lathes, robots, etc.
Motor engines, car engines
aircraft engines etc.
Trains, airplanes, cars, boats, etc.
We want to effectively fight against noise in all areas of its occurrence and regardless of the nature of this phenomenon. Knowing that not all problems can be solved on the basis of classical methods of reducing sound and vibration levels, Silencions in its research works on the development of both passive and active solutions.
Silencions’ passive solutions differ from traditional noise control methods. The principle of the technology is not only based on the acoustic properties of the material itself, but also on the geometry of the structure and its periodic character. As a result, our solutions:
have low mass and volume,
are effective in the low frequency range,
do not obstruct the flow of air
are not a thermal insulator,
can be applied to surfaces of any shape.
Our second solution is an active noise reduction system. In an active system noise reduction occurs by using an additional, external source of acoustic energy. The principle of active noise reduction is to detect the noise source characteristics producing the primary wave and to produce a secondary wave of the same amplitude but opposite phase to reduce it.
The aim of Silencions system is to reduce low- and medium-frequency sounds in industrial environments. The system utilizes machine learning techniques based on deep neural networks to reduce system latency even for complex acoustic signals.
The passive solution combined with an active solution could be the answer to all noise problems that exist in industrial environments.
Customized versions of the system are in development stage and being prepared to operate in a wide variety of environments including:
industrial machines such as CNC machine tools,
portable machining and electromechanical equipment.
The above solution is currently in its research stage, so we invite you to cooperate with us in the form of Proof of Concept to develop and customize the product for your specific industry requirements.

NOISE AND HEALTH*
Noise is one of the many negative factors that influences our health and well-being. Long-term exposure to noise can cause irreversible damage to the hearing system, such as eardrum loss in the case of short-term exposure to sound pressure peaks exceeding 130 dB, or significant damage in the form of an increase in hearing thresholds as a result of long-term exposure to noise levels exceeding 80 dB(A).
It is of particular concern to those exposed to noise in the workplace. Hearing impairment has been at the top of the list of occupational diseases for years. Every year 3000 new cases of occupational deafness are registered.
Research conducted by the Central Statistical Office on working conditions in Poland in 2020 shows that among the factors related to the work environment, the greatest threat was noise, to which 181.7 thousand people (55.1%) were exposed.
Susceptibility to the harmful effects of noise depends on hereditary and acquired characteristics and is an individual issue. Studies have been conducted to illustrate the problem of varying personal susceptibility to noise. These studies show that over a 40-year period of working in an environment where the A-weighted average sound level is 90 dB, the risk of hearing loss is 21%. Reducing the level by even 5 dB reduces this risk to 10%.
Hearing loss or damage are only some of the negative effects of noise on humans. It has been shown that exceeding a sound pressure level of 75 dB results in a marked disturbance of physiological functions, which contributes to the development of various diseases, such as pressure sickness, peptic ulcer disease, and neurosis. Weaker acoustic stimuli, with sound pressure levels of 55-75 dB(A), can cause distraction and impair performance at work.
