A sound attenuator is also called a sound trap, duct silencer, or muffler. It is a noise control system of the Heating Ventilating and Air-Conditioning (HVAC) network that is designed for the reduction of noise through the ductwork that gets either from equipment in any building or occupied spaces.
There are different designs and types of HVAC duct silencers and sound attenuators in a system offered by Aluminium technical engineering factory- tecnalco. You may select from a wide range of customized or standard sound attenuator systems for residential or commercial industries that satisfy the needs of the application. The noise caused by HVAC systems becomes too high and the ventilation areas of buildings, enclosures, and equipment rooms become very noisy. The controlling measures include silencers and louvers into the system design that makes the space free from any additive noises. HVAC systems are noisy with the sounds of the electrical and mechanical devices. There are rectangular and circular sound attenuators available for absorbing the sound in the air stream and removing the HVAC noise. The sound produced by HVAC systems is very distractive and the proper installation of sound control systems can ensure the smooth and noise-free working of systems.
Cause of Noise
There are ample reasons for which HVAC systems can become noisy. These systems have an in-built sound absorption technique embedded for keeping the sound low. There are millions of air pockets contained in the Sound Attenuators Manufacturers in UAE. that reduce the noise with the absorption of the passage of acoustic energy. The fans also produce noise with the air vibration and movement of fins. The pressure drop causes the air changes in the system that is a cause of producing the annoying noise. The loose fixing of bolts and nuts even produces a loud noise.
Types of Sound attenuators for HVAC Systems
Cylindrical attenuators: These are fitted in the ducts for silencing the noise from inside. These come with a spinning head with a tail that has the shape of a cone. The circular attenuator has two walls.
Rectangular attenuators: These are fitted over the HVAC system for noise reduction. These include dissipative silencers delivering acoustic energy with sound-absorbing media installed inside them.
In the interior wall of the sound attenuators is the insulation made for reducing the sound to a minimum level. The noise is reduced and the pressure changes in an HVAC system are maintained for making the system flow with ease.
Working of a Sound Attenuator
Sound attenuators are used as an important part of the HVAC system and these are installed to get the best effects for noise cancellation. The Sound attenuators are suggested to be installed by aluminium technical engineering factory-tecnalco, at the time of installation of the HVAC system. The insulation varies in thickness depending on the frequency of the sound produced. Sound attenuation is increased by the enhanced length of the attenuator that controls the HVAC system pressure. Regular maintenance of the system is carried out for reducing the noise and maintaining a check that there are no loose fittings in the maintenance systems.
The silencers are backed by independent testing systems in the laboratory and have applications in the following areas:
- Commercial, Institutional or Industrial HVAC duct systems
- Air handling units
- Cooling towers
- Fan Inlet and Discharge
