A functional unit for carrying out logical test cases on a test system interconnected to a unit that is to be tested, the functional unit being suitable for being interconnected between the logical test cases and the test system in such a way that the logical test cases are decoupled from the test system, and, in this context, for supporting an execution of the logical test cases on the test system as mediator.

摘要:
A device for muffling the sound produced by a fluid in a duct, especially the sound produced in an intake pipe of a combustion engine, comprises a wall, whose inside defines a flow passage for the fluid. The device is at least partly tubular, i.e. it has two openings. At the outside of the wall (3) is arranged a plurality of chambers (4), each of which is connected to the flow passage via an aperture (7). The chambers (4) are bounded by the outside of the wall (3) as well as by bars (5, 6, 8) formed at the outside of the wall (3). The chambers (4) function in use as Helmholtz resonators. In addition, a device for the conduction of a fluid with the sound proofing device (1) described is presented.
