Gorinvest JSC is a company specializing in the forestry industry. Founded in 1998, today the company is one of the leaders in the forest-industrial branch in Northeastern Bulgaria.

The issue, which Gorinvest JSC had been experiencing, for some time was the noise generated by machine Abricht. The noise peaked at the measured 130 dB,  and from 120 dB up to 100 dB at different spots of the entire working space.

At high noise levels, concentration decreases, causing more wastage in production. For this reason, measures for noise reduction have been taken.

Requirements

The noise source - the Abricht machine, generated extremely high levels of noise and led to subjective errors, which was extremely inappropriate for the working environment. Gorainvest JSC has approached DECIBEL for the design and implementation of a soundproofing cabin especially designed to meet several specific requirements. The main objective and task for DECIBEL was to reduce the sound level from 130 dB to 85 dB and the soundproofing cabin had to meet the following requirements:

- With technological openings through which timber must enter and exit
- With the opportunity, workers to observe the production process from within
- Dimensions 4m x 5m x 3.60m

The experience of DECIBEL's engineering division and flexibility in designing and creating soundproofing cabin was the factor that attracted Gorainvest JSC

Challenges

One of the challenges our team faced, was the need for the cabin to have technological openings through which timber could enter and exit. These openings are located next to the workspaces themselves, which complicated the sound insulation.

Another challenge was the presence of multiple intake aspirations, which serve to remove fine particles, to the general air duct.

Another difficulty was the size of the cabin itself, due to the large distances in the workroom and the lack of space where the structure itself could be supported.

Soundproofing cabin

Even before the start of the work process for building the soundproofing cabin, DECIBEL's team took a detailed dimensions of the space and made 3D computer models of soundproofing cabin. In order to maximize the quality of customer service, we captured the real situation of the work environment and, based on this situation, we modeled the cabin.

DECIBEL's proposed solution for noise control generated by the Abricht machine, with the requirement to keep multiple openings, was a cabin with noise-reducing panels and built-in metal panels for extra weight, as well as PZP panels.

To prevent noises from entering inside of the cabin, a silencer about a meter in the form of a truncated pyramid was designed.

The cabin was installed with two transparent sliding doors, to enable the machine operator to monitor the output.

In order to preserve the aspiration of fine dust particles, panels were designed in a special way to incorporate booth aspiration.

For the convenience of our client and in order not to interrupt the operation of the machine, DECIBEL's team was working exceptionally on Saturdays and Sundays, with the metal structure being built for two Saturdays and Sundays. The panels, together with the other parts, were built within three Saturdays and Sundays.

Result: achieved the desired measure of below 85 dB

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
