How the Use of Dampers Reduces Noise Levels in our Homes
Our home should be a sanctuary where we can settle in and relax, but is it?
Tadej Borstnar, experienced Applications Engineer at Titus Group, explains how adding damping reduces noise pollution in our homes and how to effectively resolve challenges with damping applications.
Noise pollution in our homes
Reduce noise by installing damping devices
Soft close hinges are a popular damping option in kitchens as they help cabinets and drawers glide shut with little to no assistance. The mechanism also reduces friction on the hinges, extending their lifespan and saving you the expense of repairs or replacement.
Research conducted in Europe suggests consumers consider soft closing as the most important indicator of quality cabinet doors. Key gauges of superior soft close damping included the closing velocity, the starting point of deceleration action, and the starting point of self-closing.
Improve the safety and lifespan of your products
Installing of a damper can also improve the safety of a product for example, trapping a finger when closing a cabinet door. Opening and closing, lifting and lowering lids can be uncomfortable and sometimes dangerous if heavy and sharp objects, like furniture or an oven door, descend or close quickly. This is where dampers come in. They regulate uncontrolled movements of lids and are helpful in enhancing the safety and usability of a product.
How to effectively resolve challenges with damping applicationsWhile the advantages of damping are clear, there are three main challenges which often face a designer: insufficient space for damping integration; thick or heavy doors requiring higher than normal load capacities; and applications where damping is required to operate in proximity to extreme temperatures, such as ovens or refrigerators.
Hydraulic dampers, with their longevity and consistency across wide temperature ranges, offer a compact and versatile solution. Hydraulic dampers transmit heavier damping forces than air or gas dampers.They also have a lower tendency for re-bounce compared to air dampers and use oil, which is less sensitive to compression air.
Everyday wear and tear may require damping adjustment over time for optimum soft closing. Hydraulic dampers are easily adjustable. Properties of the damper, such as damping force and moving speeds, can be altered by changing the viscosity of the silicon oil, which acts as the damping medium, through heating or cooling. The same damper design with a different oil viscosity will result in different damping forces.
Forces increase when a damper is cooled and decrease when a damper is heated. A similar principle applies to achieve different moving speeds – when increasing a piston speed through a medium, the response force will also increase and vice versa.
The damping force is generated by moving a piston/valve through a medium (shown in the figure below).
The absorber is an element that compensates for the difference in volumes when the piston rod is travelling in and out of the damper. Dampers can be ‘tuned’ to the specific requirements of custom applications.
Endless possibilities for damped movement in home productsDamping can be applied to products in all rooms of the home and Titus proprietary damping technology provides effective and consistent life-long damping across a wide array of products and applications. Thanks to extreme temperature resistance and effective performance even in circumstances with great force, hydraulic dampers excel at controlling the motion of house hold appliances such as oven and refrigerator doors, top loading washing machine lids, racks in dish washers, and large sliding door systems.
In a world where serenity is a rare and highly valued commodity, consumers are driving a demand for soft close systems as standard, rather than luxury add-on.
