Subway and tunnel ventilation

dB Noise Reduction® Inc's proven expertise and success in the design and manufacturing of subway and tunnel ventilation applications throughout North America includes movable and cleanable silencer systems designed for low pressure drop, life safety, and extreme environments.

While many competitors may use commercial grade silencers for these applications due to their "small box" modular design configuration and manufacturing limitations, dB Noise Reduction® Inc designs and manufacturers specialized industrial silencer components to perform safely and effectively over a lifetime in these extreme environments without degraded performance or quality, because these systems cannot fail.

dB Noise Reduction® Inc's expertise in subway and tunnel ventilation noise control includes highly engineered and specialized products that are designed for the unique requirements of these applications, with the primary focus on Life Safety. Since these systems are often located just below grade with exposure to the elements, the environmental conditions may require more frequent or specialized cleaning of the silencers and air movement system components.

Specialized products include the following:

• Cleanable systems - with or without filtration components:
• movable silencer baffles with removable baffle cartridges
• custom silencers
• bi-directional silencers
• vent and blowdown silencers
• acoustic barriers and temporary acoustic barriers
• full noise reduction enclosures and buildings

And many other environmental noise control product-based solutions to silence subway, metro-station and tunnel ventilation equipment.
