Soundproofing enclosure of punch press for Miba, Slovakia
The employer’s responsibility to provide a healthy work environment.
The creation of a productive and fulfilling work environment is a priority for many companies. It’s an indisputable fact that high noise levels in manufacturing not only reduce comfort, but also affect employee concentration , which leads to more defects and issues in production. The employer also has a legal obligation to protect the health and safety of staff, which includes the risk of exposure to high noise levels in the workplace. Noise in the work environment often exceeds the established work norms of 85 dB/ A, and this leads to additional costs for companies, such as additional labor compensation and additional investments in specialized safety equipment for employees. Often personal protective equipment is inconvenient and is often neglected voluntarily or involuntarily by employees, which is yet another factor in reducing their concentration and increasing their health risks.
Faced with these problems, the management of Miba Steeltec, a Slovak manufacturer of parts and cables for the electrical industry, got in touch with DECIBEL. They wanted us to provide an effective solution to this problem. In order to provide a suitable plan of action, our team had to measure the sound level. The main source of noise is a 35 ton press which generates over 105 dB/ A on impact. The equivalent daily exposure for 8 hours is between 89-90 dB/ A. Our task was to lower the noise levels to well below 80 dB/ A.
DECIBEL's engineering team designed a solution utilizing the company's proprietary PZP panels and DECIBEL Enclosure - (soundproof cabin designed to protect workers from noise generated during operation). The DECIBEL Enclosure cabins can be customized, and for Miba Steeltec we created our tallest cabin yet, standing at 8.5 m. We created a standalone frame, which would hold all add ons and PZP panels. The solution gave the client removable walls and a specific way of fastening bolt-nut connections through 3D elements between its components. Thus, the service of the press remains unobstructed by the soundproofing cabin.
The process of designing the soundproof cabin took us about a month, and so did the production period.
The installation lasted 8 days, under severe conditions, as the temperatures in the factory reached up to 50 degrees. The height of the facility required alpine methods for securing the installation team.
After the installation was complete, DECIBEL carried out measurements where we we took the results prior to installation and the achieved project values after installation.
We received positive feedback from both the workers in proximity to the press and from the management of the plant, which has already managed to report a decrease in defects and issues in their manufacturing. The results achieved have allowed for a work environment that’s more healthy and harmonious for the employees of Miba.
We recognize that our task has been successfully completed. Our customers are satisfied with the result and so we have received an invitation to solve another noise problem of theirs in a neighboring production room.
Noise problems in a manufacturing plant are common. We are specialists in solving them. When you call us, you can count on timeliness, an elegant engineering solution and a guarantee for achieving the desired results. This is what DECIBEL is all about.
PZP™ metal soundproofing panel
Metal perforated panels for internal and external use with changeable sound absorption according to the specific needs for sound absorption and sound insulation. The front part is from perforated steel with openings with different diameter depending on the degree of sound absorption. The core is from glass veil and mineral filz with coefficient of air resistance 22 850 Rayls/m. They can be manufactured to given size. Metal perforated panels by Decibel are suitable for soundproofing of: - Compressors- Chiller systems- Print factories- Industrial factories- Fabric workshops 42334234234
Soundproofing curtain DBB™
Soundproofing blanket DBB™ is made of soundproofing membrane and two - sided sound absorbing wadding. The product is created for usage in industrial buildings, homes, music rooms and music studios. The high weight of the product (5.8 kg/m2) guarantee excellent soundproofing results. Curtain DBB is offered also with nonflammable waterproof finishing layer, which makes it suitable for outdoor usage and industrial application. DBB curtains offer maximum sound control and noise reduction using a combination of sound absorption and noise barrier material. Soundproofing blankets DBB™ differ from permanent noise-reduction installations in their flexibility. While they can be used as a permanent solution for noise reduction, soundproofing curtains can also be moved where they are needed and stored out of the way when not in use. For office buildings and commercial spaces that are undergoing renovations in stages, movable soundproofing isolates the worksite no matter where the workers are located. Soundproofing blanker DBB™ has also heat insulating qualities.Sound insulation index Rw = 26 dB. DBB™ acoustic blankets are used in many industrial noise control applications. The system can accommodate ventilation and access while maintaining high noise control. Curtains are easy to install and can be moved for use in another location to accommodate machine or equipment relocation. Soundproof curtains can provide a permanent, yet the flexible, solution to each individual noise control situation. Soundproofing curtain DBB™ is suitable for: - Compressor noise control- Hydraulic pumps- Outdoor sound blanket applications- Metal compressor sound control- Outdoor fence construction- Many industrial noise control projects42334234234
Sound insulating Mesh™ panel
The Mesh™ panels are products developed by DECIBEL for indoor sound insulation and absorption. The front part is made of perforated steel with openings with different diameters depending on the sound absorption needs. The core is from a glass veil and mineral wool or acoustic foam. Mesh™ panels could be painted in any RAL Color to match different project requirements and each interior design. Mesh™ panels are of 50 mm thickness and are offered in three standard dimensions 800 x 800 mm, 850 x 850 mm, and 350 x 850 mm and also could be manufactured in custom sizes. The sound absorption coefficient of the product is Lw=0,85. Mesh™ panels by Decibel are suitable for soundproofing of: - Compressors- Chiller systems- Print factories- Industrial factories- Fabric workshops42334234234
DECIBEL soundproofing enclosure
To reduce the noise from manufacturing machines and production equipment DECIBEL has created a highly efficient enclosure that aims to eliminate the noise coming from them. The DECIBEL Enclosure is designed to protect workers from noise generated during work. In industrial settings, noise from equipment often goes beyond hearing safety limits. It also impedes communication between workers. The DECIBEL Enclosure is an efficient way to solve problems of this nature. All DECIBEL Enclosures are customizable and easy to assembled and disassembled according to the specific equipment and needs. In order to achieve supreme noise reduction from the silencer’s openings, DECIBEL has developed the CHOFF-KA silencer. The steel mechanism in the beginning of the silencer helps eliminate the open area and therefore the noise transmission, but at the same time still offers access to the enclosed machine. The main reason for choosing steel instead of the conventional rubber is to provide better noise reduction thanks to the bigger mass and the much greater wear resistance of the material.42334234234
