摘要:
Active seal assemblies employing active materials that can be controlled and remotely changed to alter the seal effectiveness, wherein the active seal assemblies actively change modulus properties such as stiffness, shape orientation, and the like. The active seal assemblies are generally configured to reduce the noise (sound waves) that is transmitted through the seal by measuring and actively canceling and/or absorbing the noise.
