Acoustic suppression arrangement for a component undergoing induced vibration

An acoustic suppression arrangement for a component undergoing induced vibration comprising:

• a polymeric component body having an interior surface and an exterior surface, said exterior surface having a panel portion;
• a polymeric containment plate having a spaced relationship from said panel portion;
• a first linear projector connected to said component body panel portion and which extends toward said containment plate;
• a second linear projector connected to said containment plate and which extends toward said component body;
• and
• a connector system for connecting said containment plate to said component body panel portion while placing said first and second projectors in an interference fit, said connector system including snap fit interlocking linear hooks on said component body and said containment plate, sealing a space between said component body and said containment plate and whereby vibratory energy of said component body is dissipated by frictional contact between said first and second projectors and said hooks.

A method of acoustically suppressing a component which undergoes induced vibration comprising:

• providing a panel portion on an exterior side of a body of said component;
• spacing away from said component body a containment plate having a fixed space relationship with respect to said panel portion;
• connecting with said component body panel portion a first projector extending toward said containment plate;
• connecting a second projector with said containment plate and extending said second projector toward the first projector to have engagement with said first projector;
• and
• connecting said containment plate with said component body panel portion while placing said first and second projectors in an interference fit whereby vibratory energy of said component body is damped by frictional contact between said first and second projectors.
