Different Ways to Soundproof Air Ducts

If you are reading this, you’re likely looking for different air duct soundproofing methods. Soundproofing is the process of reducing or eliminating noise and vibrations inside or outside a building. Like many experiences in life, there are many ways to soundproof air ducts. Methods include:

  • Air Duct Silencers
  • Louvers
  • Acoustic Vents
  • Updating the HVAC System

These 4 methods are explained in further detail below.

Air Duct Silencers

Air duct silencers are a tried-and-true method to prevent unwanted noise in air ducts. An air duct noise silencer is designed to provide the maximum noise reduction that can be obtained in a short depth. These silencers are installed directly on the fan inside the HVAC system. Air has to travel through the silencer before it can leave the air duct, which greatly reduces noise.

Air duct silencers can be used in many installations, such as:

  • Mechanical equipment
  • Fresh air intakes for ventilation systems
  • Processing air intakes
  • Cooling tower inlets
  • Exhausts
  • And much more

A vent noise silencer can provide a range of acoustical performance and pressure-drop requirements. They are also ideal for situations that need low levels of air resistance and high degrees of sound reduction.


Air vent louvers help reduce noise by literally cutting through it. Louvers can also direct airflow in different directions. Air vent louvers come in many different colors, sizes, and configurations to fit different HVAC systems. The type of louver you choose can either stand out or blend in with your color scheme.

Industrial air vent louvers are typically made from aluminum or galvanized steel, as metal is tough and durable. Aluminum is lightweight, and steel is less-likely to rust over time. The materials you choose for your louvers should be fire-resistant and temperature-resistant, as well.

Acoustic Vents

Acoustic vents are air vents that have acoustic noise reducers built into the unit. The entire unit fits inside the HVAC air vent and prevents noise penetration without reducing airflow. Unfortunately, these types of air vents are not available outside of the UK. They also only reduce noise in one room. If you want to completely soundproof a building, you’ll have to buy more than one unit. That can be expensive. The units may also need frequent maintenance.

Update HVAC System

One final method to reduce noise in ducts is to update your HVAC system. If your system is outdated, the fans and motors are likely run-down, damaged, or broken. A failing HVAC system is a huge contributor to excess air duct noise. Updating your HVAC system can greatly reduce noise in the air ducts.

How to Resolve Noisy Air Ducts?

Noisy air ducts are disruptive to the working environment. Think about the last time you were working and heard a constant whistling noise or the sound of wind traveling through your office. Those are the sounds of a noisy air duct. In order to reduce the sound of a noisy air duct, you should consider investing in an air duct noise silencer.

An air duct noise silencer reduces distracting noise from an HVAC system, which will improve productivity in your place of business. HVAC silencers are designed to provide maximum noise reduction that can be obtained in short depth. They can be used in mechanical equipment, fresh air intakes for ventilation systems, and many other installations. Before you invest in an air duct silencer, you should know what noise they block.

The main source of noise from an air duct is fan noise. Fans are designed to operate at certain speeds depending on their size. If they are underperforming or overperforming, they create more noise. Fans should always be operated near their maximum efficiency to prevent excess fan noise. Fans that are too large will generate more noise because of how fast the air travels through the air duct. This problem can be solved by using an air duct noise silencer.

Due to this fact, natural administrative organizations work to determine a maximum emitted decibel level to be kept up with during modern cycles to forestall clamor actuated hearing misfortune. Along these lines, the executives should find dynamic ways to decrease the commotion levels at their offices. In this article, we will be discussing the different types of acoustic devices and duct silencers as well as how to choose the right one for industrial operations.

What are air vent silencers?

Air vent silencers are an engineered product specifically designed to control airborne noise in ducts, openings in buildings, enclosures, or from equipment. They may also be referred to as industrial sound attenuators. Duct silencers are the best and most efficient solution to airflow generated noise. Vent silencers consist of acoustic chambers housed in a steel package covered toward one side and presented to the climate on the other. They are typically introduced at the upstream or release valve of the pipeline – where clamor would somehow or another getaway into the climate. Normal materials of development incorporate high-immaculate carbon and treated steel.

Commotion level decrease can be accomplished by diffusing the sound utilizing an extension framework and afterward engrossing the sound frequencies utilizing a dissipative framework.

The most effective method to choose an air duct noise silencer

Despite your application, you can track down a vent silencer to lessen the commotion to a sensible and administrative endorsed level. Notwithstanding, there are a few fundamental information focuses you should consider prior to picking a specific device. This includes the nature of the fluid being vented, valve pressures, fluid temperature limits, maximum and ideal fluid flow rates, material specifications, vent silencer elevation, the diameter of the pipeline, and finally, the targeted maximum noise level for regulatory compliance.

Applications of Various Ducts Silencers

Air conditioners are loved appliances, especially during summer. However, it is common for air conditioning systems to create noise if they are aged. If you live or work in an older building, then an air conditioner noise can create loud popping noises while starting up before releasing more noise as it runs. When a system is creating noise, there are simple ways to alleviate the problem. Vent noise silencers assist in canceling out the nosiness of older air conditioner systems or HVAC systems.

Is Air Duct Noise Common?

When air ducts are older, it is common for them to make a variety of noises, such as clicks, buzzing, booms, and more. This occurs when an air conditioner system is turned on, and the air begins to move. The noises are not removed simply by cleaning an air duct, as this can cause sounds to amplify since the dust has been removed. However, even when not cleaned, air ducts can also create noise.

Reasons for air duct noises are delayed ignition and more. To determine the reason behind loud air ducts, they must be identified by a professional that can present an effective solution. Air duct size and size can also assist in loud noises. Round air ducts are perfect for air pressure while angled air ducts cause more noise. High occupancy residential ductwork tends to be more susceptible to noise and duct expansion since it is made with thin material.

Loud noises from air ducts can cause a rise in concern. However, there is no need to be alarmed as it is common for air ducts to start making noise without any other signs of malfunctions. When you notice your air duct is making loud noises, seek to fix it immediately to avoid disruption.

Air Duct Noise Silencer

Also known as sound traps and mufflers, air duct noise silencers can assist in controlling noise within ducts or from loud equipment. Through the assistance of air duct noise silences, HVAC systems are prevented from creating noise and sending it elsewhere. HVAC duct silencers are installed in spaces close to where noise is generated, such as ventilation ductwork that includes equipment of fans, air flow regulators, and more.

Duct Silencers

For different HVAC systems, there are different duct silencers. If your air ducts are rectangular, a sound silencer is built off of both non-flammable mineral wool boards and abrasion-resistant fabric to eliminate noise. Circular duct silencers are built up of a circular casing of a spiral duct. The materials are non-flammable and sound attenuating. Flexible duct silencers are easier to install, especially in hard-to-reach places.
