Circular Attenuator

A circular sound attenuator is a specialised component used in heating, ventilation, and air conditioning (HVAC) systems to reduce the transmission of sound or noise through circular ductwork or pipelines. These attenuators are designed to minimise the propagation of sound waves within the ducts, which can help maintain a quieter and more comfortable environment in buildings.

Circular Design:

Tailored for various diameters and sizes to fit into different ductwork and piping systems, accommodating diverse airflow requirements.

Sound Absorption Materials:

Typically includes porous insulation, acoustic foam, or mineral wool to absorb and dissipate sound energy, reducing noise levels in the attenuator.

Baffles or Vane Design:

Enhance sound attenuation by redirecting airflow and sound waves, with design variations based on the manufacturer and application.

Pressure Drop:

Introduces resistance into HVAC systems, which designers must account for to prevent performance issues.

Applications:

Commonly found in commercial and industrial HVAC systems, installed in ventilation systems, exhaust ducts, and air handling units to ensure quieter indoor environments by reducing noise from fans, blowers, and equipment.

Compliance with Regulations:

Depending on the location and the specific application, there may be regulations or building codes that dictate the maximum allowable noise levels in certain areas. Circular sound attenuators help HVAC systems meet these requirements.
