Rectangular Silencers
High‑performance duct silencers engineered for HVAC and industrial noise control
Dynasonics rectangular silencers provide reliable noise reduction for HVAC duct systems and industrial ventilation applications where airflow performance and acoustic control must work together. Designed for flexibility and precision, these rectangular duct silencers deliver consistent sound attenuation while maintaining efficient airflow throughout the system.
From commercial buildings to manufacturing facilities and power plants, Dynasonics HVAC silencers and duct sound attenuators are engineered to meet demanding acoustic and aerodynamic requirements.
Engineered Noise Control for HVAC Duct Systems
Rectangular silencers are installed directly within ductwork to reduce noise generated by fans, blowers, and turbulent airflow. By integrating acoustic treatment within the duct system, these silencers effectively control sound transmission without requiring major changes to mechanical layouts.
Key performance advantages include:
- Effective attenuation of fan and airflow noise
- Broad‑spectrum sound reduction across multiple frequencies
- Optimized airflow with controlled pressure drop
- Flexible configurations for HVAC and industrial ventilation systems
- Proven performance supported by laboratory testing

Frequently Asked Questions (FAQ)
What is a rectangular duct silencer?
A rectangular duct silencer is a noise-control device installed within HVAC or ventilation ductwork to reduce sound generated by fans, blowers, and turbulent airflow. It attenuates ductborne noise while allowing air to move through the system efficiently.
Where are rectangular silencers typically used?
Rectangular silencers are commonly used in commercial HVAC systems, industrial ventilation networks, mechanical equipment rooms, data centers, and manufacturing facilities where ductborne noise must be controlled.
How do HVAC duct silencers work?
HVAC duct silencers use internal acoustic baffles and sound-absorbing materials to dissipate sound energy as air passes through the duct. This reduces noise transmission without significantly affecting airflow performance.
What is the difference between a duct silencer and a duct sound attenuator?
The terms are often used interchangeably. Both refer to devices installed within ductwork to reduce noise. A duct sound attenuator or duct silencer performs the same function—reducing sound generated by airflow or mechanical equipment.
Will installing a duct silencer affect airflow or pressure drop?
Dynasonics rectangular silencers are designed to balance acoustic performance with aerodynamic efficiency. Internal baffle geometry is optimized to minimize pressure drop while achieving the required noise reduction.
Can rectangular silencers be customized for different HVAC systems?
Yes. Dynasonics rectangular silencers are custom-engineered for each project. Parameters such as length, baffle configuration, casing thickness, and acoustic materials can be tailored to meet specific airflow and acoustic requirements.
How do I select the right HVAC silencer for my system?
Selecting the correct silencer depends on factors such as airflow velocity, duct size, noise levels, and space constraints. Dynasonics provides a Silencer Selection Tool (SST) and engineering support to help determine the best configuration for each application.
