Until now, it has been common practice to compensate one's units on board a ship magnetically, whereby the necessary aesthetic balance was provided by the hull and the dock or by magnetic columns enclosing the units, to which a boosted electrical current was fed.

A particular disadvantage of this approach is that access for operation, maintenance and repair is hindered by the large number of coils.

Because of the need to react to further developments in technology that can evaluate not only magnetic field disturbances but also acoustic signals, it is now essential to have not only a magnetic sensor but also highly effective sound insulation on board highly equipped boats.

The aim of the innovation is to ensure that magnetic and acoustic defence systems on board a ship with regard ^to individual installation groups do not interfere with one another and that easy accessibility to the objects being valued is guaranteed.

This object is achieved, starting from the features of the generic term "inventive device", by the features in the characterizing part of claim 1.

To solve this problem, the device according to the invention is designed in such a way that it is equipped with magnetic and acoustic signals.

IS nature to be bound installation assembly provides a sound absorbing hood, which consists of a frame, the individual rungs of which can be dovetailed and in which parts of an entire co-amping coil are laid, which can be connected to one another via plug connections when assembling and disassembling the rungs.

Dab«.! the openings in the frame enclosing the assembly, UK to ensure access to the unit, ■can be closed with removable flaps.

The flaps are coated with special sound absorption material so that in combination with the co-amping coils implemented in the frame, an equilateral sound and magnetic signature bond is achieved.

In the individual rungs 13 of the frame 3, sections of the individual co-amping coil conductors 5 are integrated.

For easy assembly and disassembly of individual rungs 13, the coupling cable conductors 5 are provided with connectors β at the respective frame rung ends 11.

The coaptation coil currents are controlled by the computer 8 and fed into the coaptation coils 4 via the connection 9.

The computer program is designed in such a way that it also takes into account the previously ignored parameter temperature of the key switch group 14 as well as the current flowing in it as well as the regulation of the voltage coil current.
