Desktop and notebook computers, set-top boxes, DVR recorders, mass storage devices and portable PDAs/MP3 players utilize similar components and subsequently encounter similar challenges with noise, shock and vibration.

Smaller components and innovative manufacturing techniques have allowed for the development of hardware that is increasingly powerful, sophisticated … and noisy. With consumers no longer willing to overlook or find homegrown solutions to noisy systems, the need for OEMs, OEDs and their suppliers to address the challenge has never been more critical.

Quiet Path technology is low cost, easy to install and is adaptable to expanding technology and can be used to optimize performance related to system noise and vibration in a wide range of applications, including:

The introduction of interactive television services and high-end digital audio and video technologies has resulted in tremendous growth – and competition – for home theatre sales. This exciting growth in consumer demand has also resulted in an increased focus on the customer experience. The noise produced by Set Top and DVR products may conflict with the consumer’s expensive audio/video equipment or simply become an annoyance if when placed in locations within the home where the added noise is not welcome. 

QuietPath’s proven technology represents an opportunity for manufacturers to reduce this noise and enhance the customer experience. Additionally, the reduction in noise and vibration will increase the life of the product and improve performance over time.

QuietPath’s systems-based approach delivers a truly optimized solution encompassing cost, mass and manufacturability considerations. The system approach employed by QuietPath relies on the strategic application of viscoelastic thin layer damping within the enclosure itself to eliminate resonant response sensitivity and “break” the source transfer paths that excite the enclosure through isolation/transmissibility design.

The portable computing market has experienced explosive growth in the past ten years however NSV management technologies have failed to keep pace. Customers are seeking lighter, more powerful notebooks and portable products. More power, smaller space and less mass have set the electronic system designer’s “chinning bar”.

QuietPath’s innovative approach addresses the challenges without adding unnecessary mass (or cost). QuietPath technology employs light, low profile materials and as a result, can be easily applied to an existing product line with highly confined space limitations.
QuietPath technology provides the most cost and mass efficient solution through two main strategies: strategic placement of thin layer damping materials (as low as .008”) which eliminate enclosure response sensitivity and minimize drive case resonances, and through engineered mounting rack isolation which provides decoupling between drives.
Every QuietPath solution is designed to meet or exceed customer-specific system requirements while addressing a variety of factors including;   
Shock/Impulse Load G force specifications
