I found the following statement that describes the differences between damping and isolation:
I found the following statement that describes the differences between damping and isolation:
"While the terms are often used interchangeably, they're two very different processes. Vibration isolation prevents vibration transmission. Vibration damping dissipates vibration energy. It absorbs or changes vibration energy, reducing the amount of energy transmitted through the equipment or structure."While the above may be technically correct, many designated isolators or dampers seem to do some of both. This was discussed on an engineering forum in describing rubber fan mounts:
"At the most basic level: Damping removes vibrational energy from the system by converting it to heat energy. Isolation attempts to prevent energy from reaching the isolated component. At particular frequencies, this can be achieved without damping. Rubber mounts are a combination of the two. Their stiffness forms part of the isolation process and their damping removes some vibrational energy."I suggest reading the AVScience, Ltd. website, associated product reviews, and then coming to your own conclusions. Their website verbiage indicates the EVPs provide "vibration isolation" but the process they describe (below) is damping:
"They (i.e., EVPs) do so by transforming the mechanical energy into thermal energy."To me, more important than the marketing description is whether the product works for your intended purpose. As many of us have learned, you never really know for sure until you try them in your own system.
