There are two types of duct sound attenuators: square and round, which can be installed in reciprocating ducting systems for air washers, air conditioners, and package units. One of Shahrokhi Technical Institute’s premier products is the round duct sound attenuators. These sound attenuators are created and chosen following the current noise level, the volume of sound absorbed by the ducts and branches, the volume of sound absorbed by the surroundings, and other noise-reducing parameters. In the absence of the initial sound level generated by the air conditioning fan, the professionals at this institute precisely measure this level using sound level analysis tools and base their noise reduction device design on that measurement.
- Ducted silencers are suitable for installation in reciprocating ducting systems, including air washers, air conditioners, and package units.
- The sound-absorbing fins are made of aluminum mesh, which is filled with stone wool insulation or foam insulation.
- The long length of the vanes and the presence of sound absorbing insulation inside them causes the turbulence of the air passing through the vanes to be absorbed and some of the existing sound caused by the air blast and the sound of the device's fan is absorbed by the insulation. As a result, the sound in the environment is reduced to a suitable level according to the performance space.
- Moving the air flow directly to increase the flow rate and reduce the pressure drop.
- Hard rounded tip to maximize noise reduction.
- Having hard surfaces in the place of air passage and minimizing the amount of pollution accumulation.
- Round inlet to reduce disturbance, pressure drop and sound produced by the silencer.
- Without any protrusions to eliminate disturbances and noises produced in the speaker.
Attributes
- In air conditioning channels, generally due to fan operation, whether axial fans or centrifugal fans, an unpleasant sound is scattered in the ventilated environment, and the intensity of this sound depends on various factors such as the type of fan, the distance of the fan from the location, the type and type of channels and Branches, the type of walls and other such factors are different, but in any case, the presence of these sounds will create an uncomfortable environment for the residents.
- Today, in the world, they use channel silencers to solve this problem. These silencers with a special design, in addition to minimal impact on ventilation air flow, eliminate the sound produced by air conditioners to a very high extent.
- The material and design of these silencers are such that they absorb sounds produced with all kinds of frequencies and in the range of human hearing (from 63 to 8000 HZ) they provide comfortable environmental conditions in terms of sound. In this regard, the design of a sound absorber that can provide these conditions in the environment is of special importance, in the case of an incorrect design, the sound absorber will not only not be able to absorb sound, but as the factor that creates sound, it will double the problems. make
