Noise Reduction Solutions

Reduce Industrial Noise at the Source

Excessive noise from control valves, regulators, and process equipment can affect workplace comfort, personnel exposure, and day-to-day operations. ECI helps you explore noise reduction solutions matched to your equipment and application—from noise-attenuating valve technology to custom-fit acoustic insulation.

The right solution depends on where noise is generated, how it travels through the process, and the operating requirements of the equipment. ECI can help you evaluate options for your application.

Fisher™ Whisper Technology

For noise generated by control valves and downstream piping, Fisher Whisper Technology offers specialized trim and attenuation options designed to reduce aerodynamic or hydrodynamic noise while supporting process performance. Product options include Whisper NXV Trim for rotary valves, Whisper NXG Trim for globe valves, and the 6060 WhisperTube Modal Attenuator for in-pipe noise attenuation.

Explore Fisher™ Whisper Technology to learn about the technologies and their application considerations. Noise attenuation and flow performance depend on the selected product and service conditions.

Shannon Thermal & Acoustic Insulation Solutions

When sound from valves, instruments, or process equipment needs to be attenuated around the equipment, Shannon acoustic blankets provide a custom-fit, removable option. The blankets are designed for acoustic and thermal insulation applications and can be removed and reinstalled to support inspection and maintenance access.

Explore Shannon Thermal & Acoustic Insulation Solutions for details on blanket design, construction, and installation. Reported noise reduction varies by application.

Application-Focused Guidance

Noise challenges vary with process conditions, equipment design, and the surrounding environment. ECI works with customers to review application requirements and identify solutions for consideration—whether the priority is attenuating noise through valve technology, adding acoustic insulation, or evaluating both approaches.

A properly selected and specified solution can help address noise at the equipment and support workplace noise-management efforts. Final performance depends on the equipment, installation, and operating conditions.
