Vibration eliminators are specifically designed to reduce and control noise transmission through metal ductwork in residential installations. These devices are typically installed at points where the ductwork connects to the HVAC system or other mechanical components, effectively absorbing vibrations and preventing them from traveling through the ducts. This results in a significant reduction in noise, contributing to a quieter indoor environment.

In contrast, flexible connectors can also be used to mitigate some degree of vibration and noise; however, they primarily serve to allow for movement and expansion in the ductwork, rather than specifically targeting noise transmission. Duct tape is not an effective solution for reducing noise; it is used more for sealing air leaks rather than isolating vibrations. Screws, while essential for fastening duct components, do nothing to address vibration or noise control within the system.
