ABSTRACT:
A vibrationally and acoustically insulated structure includes a structure using enclosing a source of internally generated noise and vibrations. The structure further includes a vibration and acoustic insulating device positioned over a portion of the internal surface of the housing and having a vibration damping portion and acoustic absorbing portion. The vibration damping portion, such as a constrained damping layer having a continuous damping layer and a segmented constraining layer of individual rigid segments, reduces vibrations transmitted through the structure housing. The acoustic absorbing portion includes an acoustic barrier layer adjacent the constrained damping layer, an acoustic absorption layer adjacent to the acoustic barrier layer and one or more mounts for mounting the acoustic absorption layer and acoustic barrier layer to the constrained damping layer. The acoustic absorption device reduces the reverberating acoustic waves within the structure housing. The mounts typically include an elongated threaded post, such as a snap nut, extending from one of the individual rigid segments and a threaded fastener threadably engaged with the elongated threaded post to secure the acoustic absorption layer.
