Rescue hovercraft contains a low-noise ship's cabin with a suspended acoustical ceiling. Low-noise cabin comprises a metal built-up carcass consisting of bearing section structures accommodating sound-and-vibration insulating elements. In this case, the vibration isolators of the lower suspension of the cabin are made in the form of a dry-friction spring damper.
EFFECT: noise level is reduced and efficiency of vibration isolation is increased.
