Abstract: A tunable vibration dampener includes a support including a first support wall and a second support wall spaced from the first support wall and a mass suspended between the first support wall and the second support wall. The mass has a first side surface and a second side surface. A first support system having a support member connects the first side surface and the first support wall and a second support system having a support element connects the second side surface and the second support wall. At least one of the support member and the support element is adjustable to establish a selected attenuation frequency for the tunable vibration dampener.
