In this video, E-A-R Applications Engineer Chirag Patel explains the principles of vibration decoupling and why it is important for OEMs. Using a music box and a table, Chirag demonstrates the difference between a coupled and decoupled system, and the noticeable impact that it can have.

With the music box in direct contact with the table, the vibrations produced are able to transmit freely throughout the structure, effectively filling the room with amplified sound. While this may be a pleasant experience with a music box, it is certainly not something you want happening in your laptop or smartphone. When an isolation material is introduced, in this case ISOLOSS™ SL elastomer and CONFOR™ EG foam, the vibrations are decoupled from the table and noise levels are drastically lowered. E-A-R materials also go a step further, as they are specifically designed with high damping properties to dissipate the energy.

Other than reducing unwanted noise, why is all of this important? Isolating and damping the vibrations also help protect the components of a product from premature wear while increasing the reliability of sensitive critical functions. For example, when ISODAMP™ isolators are used to decouple vibrations in a consumer drone (UAV), it can assist in lowering the overall noise of the drone, protect the PCB and flight controller from harmful vibrations, and assist in the stabilization of the camera.
