Shock, Noise, Vibration and Harshness Solutions for Improved Performance and Reliability

Why Use NVH?

Many applications are subject to extreme environments where Noise, Vibration, Harshness (NVH), and shock are prevalent. These conditions can wear down mechanical and bonded joints, mating surfaces and device ruggedization or negatively impact end customer satisfaction with unwanted noise. Integrating components that effectively absorb, prevent or distribute this extra, intermittent energy enables smoother, quieter, more reliable performance by end users.


In addition to NVH, bushings and washers offer mechanical benefits and electrical insulation. This increases the structural integrity, electrical performance and reliability of the device.


Cushions and Pads are easy, cost-efficient solutions that combat friction and vibration. They also aid in protecting applications and solution from mechanical wear and tear.


Boyd develops foam solutions for NVH (noise, vibration, & harshness) including seals, gaskets, pads, foam tapes, door panel sealing and more. These foam components are used alone or integrated with other solutions.

Grommets & Vibration Isolators

Isolate vibration utilizing grommets and other mechanical components ranging from simple to complex custom sizes, geometries and temperature extremes. Grommets are necessary in more high-power systems, especially those with moving parts and high vibration.

Isolator Seals

Isolator Seals protect from contaminant ingress as well as shock, vibration, and harshness. These seals are a low-cost solution to improve reliability and ensure longer lifetimes.

Stanchion Pads

Nylon stabilizers that reduce stress on leads during post-processing operations. They also provide a stable mount to resist shock and vibration damage to leads. Reduced stress and vibration protection for leads enables more reliable performance, longer product lifetimes, and reduced maintenance.

Molded Mount Bumpers

Molded Bumpers offer shock protection and vibration damping to prevent wear and tear. Boyd molded mount bumpers can be custom-designed to any configuration.

Stamped Dampers

Stamped metal dampers are ideal for long term and dependable performance damping requirements for hard disk drive (HDD) dampers. Boyd delivers zero‐defect metal stamping and fabricated products that adhere to international standards.

Vibration Mounts

Shock and Vibration isolation systems and vibration mounts protect sensitive components and devices by providing cushioning and less friction. By mitigation vibration, devices last longer with more reliability and better performance.

Ruggedized Protection

Against vibration that degrades the user experience.


Enhanced Comfort and Safety

Manage undesirable acoustics and movement from regular or extreme consumer use.


Protect Against Extremes

Including drop shock and collission impact mechanical energy.


Reduce NVH and Absorb Shock

Boyd offers a wide variety of solutions to reduce NVH and absorb shock. By selecting the right material, manufacturing process, and geometry for products like vibration isolators, stamped dampers, grommets, bumpers and cushions, Boyd enables device and technology designers to focus on improving the functionality of end products instead of troubleshooting NVH and shock issues.

Types of NVH & Shock Solutions

DAMPERS: Vibration damping can be added to a structure in many ways to reduce excessive resonant behavior. The most common type is material-based damping created by straining visco-elastic materials (VEM) in either shear or tension/compression. Performance is optimized by selecting a VEM with maximum loss factor in the temperature and frequency range of interest, and with a stiffness range that maximizes strain energy in the damping element. Vibration damping requires optimization through material selection, treatment design and placement to ensure good performance.

ABSORBERS/BARRIERS: For conditions involving excessive radiated noise, a common countermeasure is to enclose the noise source with acoustic absorbing materials to reduce noise levels before they are transmitted to the receiver. Often a dense barrier layer is incorporated to reduce the transmission of noise through the enclosure. Design parameters like foam type, thickness and cover films laminated to the foam are adjusted to achieve good acoustic absorption over the needed frequency range.

ISOLATORS: A common method to mitigate vibration transmission is to insert compliant materials that isolate and de-couple the vibration. These isolating materials are converted into many geometries in a wide range of parts from die-cut isolation gaskets, grommets, bumpers or cushions, to molded rubber components. The isolator is selected to be as compliant as possible and with optimum damping to control unwanted amplification.
