Soundproofing of Air Extraction System
The wholesale and service company Steyr-Werner Technischer Handel GmbH is represented in Austria for its customers with 8 technology and service centers, direct sales, and a webshop. With a turnover of over 50 million euros, Steyr-Werner Technischer Handel GmbH is a leading company in technical trading in Austria. Over the years, the company has also developed into a C-parts management specialist, that optimizes its customers' purchasing and logistics processes. In addition, Steyr Werner is also a leading manufacturer of hydraulic hoses for the industry.
The production hall for hydraulic hoses is around 2000m² in size. In it, rubber hoses are cut, configured, and assembled according to customer specifications. An air extraction system at the rear end of the hall ensures that dirty air that arises on the machines is extracted and led outside. This suction machine generates a permanent sound at very low frequencies, which has a very disruptive effect on employees in the production process. Communication between the workstations was disrupted and the employees' concentration clearly decreased over the course of the day.
The head of work safety and quality at Steyr Werner did his own research for companies that can analyze and solve noise problems. In doing so, they came across DECIBEL in Austria, where they deal with the market with their own team. Steyr Werner was particularly enthusiastic about DECIBEL's holistic approach - analysis, concept, products, installation, measurement.
DECIBEL came to Steyr Werner's site and analyzed the situation. A concept was drawn up in which the customer was presented with a presentation of the improvements that will be made after the installation of the new housing, even before the order was placed. The housing itself was mastered by means of metal-perforated panels, an inspection door, and two fans to cool the extraction system. The installation presented certain challenges, as existing light strips and ventilation pipes had to be taken into account through recesses in the metal-perforated panels.
Even during the installation, employees from Steyr Werner approached the assembly employees from DECIBEL with words of appreciation. The improvement was clearly audible. With a reduction of more than 12 dB, the target was clearly exceeded. We hope that the employees will now feel even more comfortable and that Steyr Werner will offer them an even more attractive working environment.
Acoustic Louvers DECIBEL AL®
DECIBEL AL® 300 and DECIBEL AL® 600 are a single louver attenuating system. The louvers are made of steel sheets, filled with sound-absorbing material, and one-sided cover by a perforated metal sheet. The standard sizes of the box are 12'' х 40'' х 40''. or 24'' х 40'' х 40''. This makes the attenuators easy to install on facade openings or hang on support metal construction. They can also be stored as standalone screen wall attenuators. DECIBEL AL® 300 and DECIBEL AL® 600 are used mainly in engine rooms, ventilation openings, power generator rooms, boiler rooms, cooling towers, or any other industrial or HVAC systems. DECIBEL AL® is made of galvanized or powder-coated metal frame and modular parts, including sound-insulating and sound-absorbing front panels. The wings are made of galvanized sheet metal with a finish of perforated sheet metal and filling of sound-absorbing material. DECIBEL AL® sound-insulating louvers are specially produced for use in cases where a large amount of air must pass through a louvre and where the installation space is limited. This includes enclosures, generators and cooling / heating systems. Two standard sizes of DECIBEL AL® (12'' and 24'') soundproofing louvers are produced, each with its own properties in terms of air flow, sound insulation and installation depth. DECIBEL AL® can also be produced in non-standard sizes. Standard dimensions of DECIBEL AL® 12'' х 40'' х 40'';24'' х 40'' х 40''; (Non standard dimensions available upon request) Material: Galvanized steel;Perforated sheet metal;Sound-absorbing acoustic material;Aluminum Finish and colours : in RAL Properties: Small installation depth;Easy to install;Snow and rain resistant; Installation: By direct fastening with screws or оn an installation frame;The specifics of the installation are determined by the technical features of the project. 42334234234

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
